Hacking my garage door with the Raspberry Pi Pico W
HTML-код
- Опубликовано: 6 июл 2024
- Now my wife doesn't get angry at me for leaving the garage door open all day!
Here's the open source Raspberry Pi Pico W garage door sensor project, with instructions for how you can set up the same thing at your house: github.com/geerlingguy/pico-w...
And here are the items I purchased to complete the installation (some are affiliate links):
- Seco-Larm SM-4201-LQ Overhead Door Sensor: amzn.to/3EjG1qp
- RPi Pico Terminal Block Breakout Board: amzn.to/3tkZQY9
- Small breadboards for prototyping: amzn.to/3A6ha7b
- Breadboard solderless jumper wires: amzn.to/3UHCmYO
You can also buy the Pico WH ('W with Headers') if you want to avoid having to solder headers on the Pico W yourself.

Jeff, you stopped short. That same pico can not only alert you of the open/close status but can also be used to open/close your door remotely. You’ll just need some of that two-conductor wire to go from the pico to the terminals on your opener where your current door opener switch connects. From there it’s just a little more yaml and you’re done.
True, but then I have to trust my own ability to not code something dumb like accidentally having the garage door open every time I drink a soda or something... or having it close on Red Shirt Jeff's head every time he walks under it!
@@JeffGeerling or code it to trap RSJ in the garage so you know its safe to unbox something.
new to this stuff, but I was hoping that was the case.
@@JeffGeerling that's why closing can be automatic but opening is always user initiated 😅
@@JeffGeerling Your electric garage door opener has a sensor at the bottom that stops and reverses the door if it detects an obstacle in the doorway as the door closes. The safety sensor overrides any "close the door" commands.
Neat to see Pico W entering space that ESP32/ESP8266 dominate. Pi foundation need to ramp up production!
With the new Bluetooth Proxy I think the ESP32 will be king of the hill for some time to come. I've replaced some ESP12F (8266) with ESP32-C3-12F (can be drop-in replacement, depends on what pins the device use) to give me Bluetooth Proxy in existing smart sockets.
Edit: Seems Pico W has Bluetooth LE hardware, maybe once SDK support is in place ESPHome can leverage it for Bluetooth proxy as well. That'd be interesting!
They totally have production for these things … It's the big boy Pi they can't seem to make enough of, probably still because scalpers. The way Pi 4 prices have been going, I sort of have to wonder if we can run Raspberry Pi projects on Nvidia GPUs left over from mining? 🤪🤪🤪
Pico's are about the only thing you can buy right now.
rp2040 lacks the built in firmware security which makes it pretty limited for commercial use other than some basic application.
There is a 100pcs reel of RP2040 I got for $0.93/piece from Ali sitting in the post office, waiting to be verified.
Judging by reviews and the price from LCSC, where it probably came from, it's legit
and the total BOM cost for my custom RP2040 dev board would be $2 with USB-C and 32Mbit flash.
So, I'd say their production is in a pretty competitive state in MCU department..
My grandfather sometimes forgets to close the garage door. 🤣
I was totally gonna do this. Beat me to it! Nice!
What a throw back intro Jeff! Love it :)
I genuinely can’t express how much your videos have helped me not quit going to school for a career in computers, thank you!
Great video Jeff. I actually did something similar years ago with an arduino and a distance sensor that I mounted on the ceiling of my garage pointed at the floor. This has the advantage of not only being able to tell you if the door is up or down based on the distance, you can also determine if a car is parked in the stall assuming the door is down.
That's such a clever solution!
So happy to hear the "Here in my garage". It was playing in my head from when I saw the thumbnail to when I opened the video and you meeting that expectation was some good dopamine
7:48 Holy moly I designed that Pico wall mount thing! Even if you didn’t end up using it, what a place to see one of my designs appearing for the first time!
Haha thanks for making it! I was about to run with it when I noticed the breakout with the screw terminals... and I decided I would be lazy and not solder the wires in the garage :D
Since I didn't get attributed (and didn't ask in my previous comment and my case didn't get used, to be fair) - if anyone wants to find the model for themselves, search on Printables for "274753" (the item ID) (I'm assuming I can't link things!).
What a throwback with that intro.
You never cease to amaze. That's awesome work and your explanation is easy to understand. Thank you!
I like the modern simplicity. I did something like this about 12+ years ago with a hardwired connection and a much less powerful microcontroller. I pre-computed sunset/sunrise times for my latitude and longitude for each day of the year and triggered the alert/warn/chime only when the garage door is open 30 minutes past sunset....since the kids and wife were leaving the garage door open.
Cool the guys from Nabu Casa are making these work as well! Thanks for sharing an persevering in the solving of the initial blinking issue!
I currently rent so I can't do much modification to my home. I dreamt of being an electronics engineer but that never materialized. I may finally get into the maker scene due to a job change and the standard of living improvement that new job brings. I have been watching 3D printer videos but these videos by Jeff are SOOO inspiring. I plan to have a massive ESPHome network that covers everything from security to reminding me to take out the trash and walk the dog (I have no dog....yet!). Thanks Jeff for another great video! I wish you success on your journey to remission and good health.
I did the garage door opener project 2 years ago. It was a fun project with the kid, but I did it with a rpi0 and lots of code since the original project was so insecure. :)
Great video again! Good to know ESP home supports the pico now as it is really good to have more options. Look forward to the Pi display and LED matrix video(s). Thanks for making these kinds of videos!
Dude. Every video you put up is inspirational. I don't own a home, have the space or resources to achieve this. But, when I do, your vids will certainly be a guide.
Glad to see you're doing well by the way.
More vids please 😀
That looks amazing, mate, and I'm glad you're well enough to return to the workshop!
This is neat. I hope I have a garage door one day so I can do this as well! Glad to see you back at home brother!
These are pretty awesome boards. I'm using them in a project with my friend. These Pico boards are replacing our pi3 and pi4 boards in our remote controls allowing us to build them cheaper and smaller.
You are spot on with the standardization options with Pico, compared to at least 5 different esp32 board layouts I got.
the Tai Lopez cold open got me dying.
Nice work and thanks for explaining why you chose the picow over esp32. One ide on home assistant is to also use the automation to alert you when the garage door is open when no one is home.
I've had a handful of IoT devices fail when WPA2/WPA3 PSK are offered on the same SSID, then others when very low speed rates were automatically disabled by the network controller. Since most of the IoT devices on 2.4 don't need to have high speed, leaving it at the old 802.11b/g/n settings seems fine and everything needing speed should just have 5ghz wireless.
man I really enjoy your videos, and I'm happy to see you are better. Keep it up Jeff
I had my first foray into ESPHome and Home Assistant this week! And a similar day or so of debugging 2.4GHz wifi networks. Found some smart plugs that don't phone home and were built for ESPHome + Home Assistant which is exactly the kind of setup I wanted.
I just was finally able to order a pico w. Very interesting project. I don't have it yet, should be a few days more. I'll look forward to trying this when I get it. Thanks
Glad to know I'm not the only one who gets reminded they left the garage door up :). Was thinking of doing this with code, but Home Assistant seems like a better option. Cheers!
Morning from sunny Australia. Glad to see you improving,
Thank you so much for this video and the detailed step-by-step tutorial. I had issues getting ESPhome to run on my Pico W, but now it just works! 🎆
Ahhhh... Now we know why you were asking those questions on Twitter. :) Glad to hear you got it sorted out. 😁👍
Ha, exactly!
Great Video, I like different ways to do the same thing. I did mine like some of the other commenters here did. I bought a cheap aqara zigbee door sensor and added it to home assistant. No coding at all needed and setup is just adding the sensor to the door and the rail. Works perfect every time to and is fast and local no cloud at all.
Thank you for the great content and for publishing all your hard work!
Great video Jeff! glad you see/hear that you're back on your feet and back with a great project. looking forward to the 'dashboard' display, something I've wanted to do for my home for YEARS!
PS: MicroCenter is also my go-to place for electronics DIYs, RIP Radio Shack ...
Micro Center is close to the Radio Shack of my youth... though they don't have quite the selection of random A/V gear.
I wish we had MicroCenter here in the UK. We have nothing that replaces Radio Shack (known as Tandy over here for some reason). RIP indeed. Briefly we had Maplin, but then they moved inexorably over to selling consumer crap and not components.
@@cooperised Tandy Corporation was the parent corp of Radio Shack.
Love it! Other than the obvious, "The garage is open, would you like me to close it?" functionality that I'm sure you'll add soon.
Awesome Jeff hopefully I can make a project work for my Remote Gate. Thank you always for your amazing videos 📹
Subbed just for the intro, I'm glad that even in 2022 that meme still isn't dead.
Very cool, Jeff! Now I have something to do this winter.
Really looking forward to the dashboard build! Curious to see how the UI/UX will turn out thanks for the video
Jeff, great video! Thanks for reminding me about the Pico W's abilities. I've been programming/building everything with ESP in the last few years and bought some of these PicoW but they are "just laying around." I'll give them a shot!
My biggest project is a build of a (cheap) temp/humidity/light/motion/water sensor which I can place around the house in various zones. WiFi of course, and running from rechargeable Li Ions. I can recharge them using a "portable battery bank" with a 5v USB. Yeah I know--walk around to every one of them in the house and charge them up every nine months. But I need exercise. :)
Keep up these great videos!
"What are you doing with that USB battery bank?"
Exercising! 🤷♂️ :D
Nice. I'm also currently building a display for weather and latest phone calls with the pico.
0:40 Your musical tastes are immaculate. I didn't know you listened to all of the top 40 greatest hits!
Cool to see that ESPHome supports RPi Picos. I´m living in a department, so it is limited what I can automate. It is nice to see all the automation projects waiting for me, when I buy a house. I´m still waiting for the RPi Pico WH to get available. I always buy micro controllers with pre-soldered headers, because of poor ventilation options in my apartment.
0:01 I just bought this Raspberry Pi Pico and replaced all of the computer circuitry in my car and turned it into the world's very first open source car! Until next time, I'm Jeff Geerling.
If anyone could do it, Jeff could. Since I am currently looking at a painful amount of money to replace a certain module in my car I would say "Do it Jeff"! Heck, if you get together with some of the other tech and car RUclipsrs it would make a great collab project! You could open source the code and sell pre-made hardware for those that don't want to solder. Imagine how much revenue that could generate for you and the others in the collab. There is an endless supply of cars needing computer modules out there, all to do different things in different ways. Imagine an entire army of open source programmers reverse engineering those stupid proprietary modules and using an open source platform to make them even better. The auto industry would hate us ;-). If you or someone else takes this project and runs with it, just remember who gave you the idea. Marco - The GPUtuber and cggnow ;-)
The troublemaker in me would hook up a camera or some other sensor that would trigger the door to close on someone as they walk out ;). But seriously, I can see myself peppering these Picos throughout my house to do various things related to this. Great video!
09:02 That is probably the cutest screwdriver I've ever seen
Ha, one of the dozens of little screwdrivers that come with a kit (in this case, that breakout board)... I have a little baggie full of those things, in all colors!
Love the home automation videos ❤
Glad to see you're doing better.
nice video, Im using ESPhome for a year now, really happy with it, ESP32's are stable and fast, good to know the Pico is In the mix too
I absolutely love the Pico! While I'll always have a soft spot in my heart for programming the PIC in Assembler, I'm learning MicroPython to be able to knock out embedded projects more quickly, and ESPHome is now on my radar.
Yeah besides the overhead/memory use, MicroPython is great for quickly hacking something together.
Thanks Jeff. Long time sub. Hope the crohns is doing better!
Pretty cool. I wanted to be able to open/close my garage door and see if it's open/shut. I was looking into a Pi Pico, but I was having trouble finding out if was going to open the door if the power failed and came back on. I couldn't get my hands on one anyway, so I ended up using a Shelly 1. Not as big a learning opportunity, but it works great.
@0:01 - Jeff's meme game is S tier.
Thanks Jeff, great work as usual.
Great video, like always. I can't wait for your future videos!
Pure awesomeness Jeff, thank you🙏✌️
Looks great. I've wanted to do a local garage door sensor project for a bit.
The biggest reason to use the Pico instead of an ESP is, IMHO, the fact that with a Pico, you're getting a working board every time. Every. Time. Now try to find a Wemos D1 mini that has a decent 3V3 regulator. Or literally any reasonably priced ESP device with an OK regulator. It's hard. So many of my ESPHome nodes keep rebooting or dying after a couple months because the regulators can't keep up. The only ones that are still running fine are the ones I power directly from the 3V3 rail or the ones with an LM1117 regulator.
1st section title: Here in my garage...
Did I have heard that anywhere?
Solid start right there
I was considering doing something like this hour. Garage door place it with one that has a built-in and I also installed a surveillance camera as well. It's still pretty slick though on how you got everything working.
This is a great project for getting to know the workings of ESP Home and RPi Pico. Simple and way less expensive version of the same thing is a wireless window/door sensor with ZigBee or Z-Wave. No coding, no flashing, no soldering, nothing. Stick, add to home assistant, add to dashboard. Done.
Good video Jeff, we all have to remember i guess, just because we have the best doesn't mean it works the best! IE wifi6 :) Glad to see you are feeling better too !!
Pi touchscreen!! Excited to see that project!
Glad to see you're doing so much better. I just jumped into HA too. Looking for a way to use Pico for an air pressure monitor for my air compressor. This helps get the ball rolling for me.
Nice idea! I've been working on some other environmental monitors, but hadn't even thought about things like air compressor monitoring. Though my current model is an old harbor freight that keeps going despite my best efforts to kill the thing!
@@JeffGeerling The harder you try, the more they fight back. Until the day you really need them, then they die. Tools are spiteful like that.
Very selfishly I look forward to your future videos regarding micros and Home Assistant. I have been building esp8266 and esp32 based sensors, switches, and controllers with HA for the past few years and very interested to see what new ideas you can share.
Also been meaning to add a touch panel interface so the rpi idea you have is also right up my alley.
Thanks!
The touch panel may need to wait for the new year though :(
But it should be a fun video!
@@JeffGeerling No worries and no rush. I'll still be here, god willing. 🙂
Hope you and your are doing well! Enjoy the holidays.
Did this with an Arduino many years ago, before I knew about Home Assistant (~2015). Arduino was connected to the door button, and I put a magnetic switch mounted to the door rail just like you have there. Had a webserver in my homelab running a single page site with some JS/ajax to request data/send commands to the arduino using PHP. Put it behind a reverse proxy for auth and security and made an Android webview app. Used that until about 2 years ago until I bought a new opener with MyQ. Thing ran for years without an issue, but it's nice not having to worry about maintaining it anymore.
Cool setup, but I think it can be done a lot easyer. I simply used some aqara door sensors (zigbee) and mounted them on the steel rails in the roof where the doors move. However I did use a raspberry pi with a relay switch for opening and closing the door throught the garage door motor.
Thanks for your content! :)
Supercool project! 💪
“Here in my garage…” if I could I would subscribe again!
Lol the Ty Lopez reference was great!
I LOVE complicated yaml config files 😍 esphome looks awesome
This is the best intro to a garage video in a long time. KNAWLEGE
jeff you are a freaking genius i wish someday i could be like you
I really like Google Hubs and casting Dashboards to them, if you dont need the 10" display its a cheap and easy option. Home Assistant guys are doing the lords work:D
Ohhh my, I haven't heard that ad in ages. Amazing implementation :kekw:
Depending on what else you want to automate later, a sensor that indicates whether the car is in the garage could be interesting.
I'm glad other people work on silly problems for 2 days straight resulting in hair pulling -- I thought it was only me having issues like this
Great video of the Pico with esp home, now we just need Bluetooth support to complete the package
I did something similar but I built a PCB with a small mosfet that triggers a relay and is connected to the garage door controller that also opens and closes the door from Home Assistant.
Man I respect the N-O-D-E Pinouts shirt. It's a shame their channel is inactive now, but maybe they'll return again someday. Nice video though Jeff, been waiting to do this with some ESP-01 boards
Great video Jeff :)
Now you need to add some solid-state switches to the Raspberry Pi Pico W so you can remotely open and close the doors yourself :D
Great video as always, Jeff! Can you please do a setup for automatic watering for a garden with something like RapberryPi Pico?
Tai Lopez intro = immediate like. that was a good chuckle
Awesome video! I really would like to see you create a Raspberry Pi Home Assistant Touch Dashboard! I currently have lots of devices in my home with home assistant and would like to see what you come up with on a center home dashboard for home assistant! :D
2:18 that socket thing looks super convenient!
Love the knowledge bomb in the intro :)
KNOWLEDGE.
Liked this video. What more! :)
Seriously, this a excellent, pragmatic, and educational video. 👍👍
Knowledge!! Hahaha great vid as always! 🙌🏽
Thanks for another wonderful video!
One more thing you can do with this is have it close or open the door for you. If you have an older garage door with wired buttons on the wall you can tap the wires and have it run to a relay. The button on the wall is nothing but a momentary switch (normally open), so wire the relay to normally open and have the pico trip the relay and close the loop for the switch for like 500ms and you now have a automated garage door opener. I have down a number of houses with the old HAI boards to close an open garage door after x amount of time. Makes life simple, plus you can close it from any panel or phone so no running to the garage to close it.
Love the videos! Inspires me to make my own little home rack, much to the chagrin of my spouse
Hi Jeff! Please note that mounting reed switch on the metal, will result in false/positive sensor readings after a while, when the magnet will magnetize the gate frame.
Great Video. Does HomeAssistant look for updates for the software/firmware of the devices you add? I think that would be beneficial with an array of potentially piecemeal devices. I think ESPhome had a non critical vulnerability last year. And probably a good idea to have your wifi devices on a guest or limited wifi network.
I definitely saw R Pi Pi Cow and was confused for a second. Thanks for the laugh. :)
An alternative to spending nearly $30 on a sensor, which is probably just a reed switch in a fancy aluminum casing... you could just use a magnet, reed switch, and a couple of L-brackets (which should only be a couple of bucks total). You could get fancy and 3D print a case or etc for it... if you were feeling fancy.
Go Tai! 😆
.. I'm guessing no one else got that hey Jeff...
Hilarious intro. Great content, too!
I like that you started with a practical problem instead of getting the tech just to have it. Don't get me wrong, I own lots of tech hardware and tools I have no use for yet because I like the tech and I'm pretty sure I will use them in the future. However, it's always good to be able to tell your significant other that you are spending time and money to solve a real world problem that they identified. It earns relationship points ;-)
Exactly!
Home assistant.. really cool to find out about that, will be setting that up soon! :)
Careful, it's quite a rabbit hole and you'll start wondering what happened to your weekends as you automate and monitor things you never knew possible :D
So cool! I want to build this. Thank you!!
Now you just need to get an option into home assistant to shut the garage door without having to walk to it to close it, possibly also motion detection to see if there is anything in the way of it closing properly or checking for movement near the door before it attempts to close.
