- There was a lot to get through in this video. Long story short they are a good little loot box, but garbage as a product. #WouldNotBuy

All the earlier Arlec/Deta stuff used to be ESP based. I have some of the older items and was able to flash the power plug head replacement with no issues. The whole industry changed over to the new Tuya chips. Each of these companies could have achieved larger market share if they were developer friendly. I also hate Tuya.
I know, the good old Tuya stuff that you could use tuyaconvert with. -sigh- I really hope tuya ends up in a garbage fire that keeps hobos warm one day
If you manage to get OpenBeken installed on this I would love to see how you did this and and what the final results were. Cheers 😊
It's on my future plans. I've got a giant notepad++ document of sh!t to bust open and do things too hah. Welcome!
I'm looking for a strictly energy monitor plug and one that will monitor energy going in reverse, my current non wifi plug will go in reverse as it has solar panels plugged in, will these be the same?
That is bloody interesting, had never thought of that!
Will leave your email in my inbox, and try to jam 240V backwards through one this weekend when I am next back at the workshop. Once I've tried it, I'll let you know!
Hey so I tested this and unfortunately it does not work. When connected in reverse, the controller does not get powered. I can only assume that this is due to the side of the relay that the controller is on. I tried both the old and the new version, but no luck with either! Sorry mate, you'd have to custom make something for this!
Hey mate,
just bought a couple of these (before watchingthis video sadly enough :-)), but luckily bunnings is good with returns!
I'm very much in the market for a device that does what this one offers: energy monitoring and - if possible - remote on/off switch for the GPO. Are there other products that you would happily recommend?
Cheers,
Peter
Hey mate yeah I love Bunnings for that! Kmart too actually
10/10 recommend these: ruclips.net/video/o3iGvt1FTDc/видео.html #ShamelessSelfPromotion (link in desc)
@@PlatimaTinkers thanks mate!
@@petersmolderen2037 Any time!
When the mains power goes off and then on again, do the units remain off (e.g., relay off - lamps off). If one is away for a few days, we really wouldnt want lamps to be running all day and night? Additionally, one of my suppliers recently stopped selling another type of device (not an arlec device) due to security breaches (china or others monitoring activity - very mysterious?). Are these esp and other devices safe in that way?
I have a couple of these. I just tested your question. Note only tested quickly.
I had a lamp plugged in and on, then turn the power off. The lamp went out.
I waited 5 minutes and then restored the power,
The switch came back on (blue light on top is on) and returned to the on status, my lamp is back on.
I then did the opposite, had the switch off and turned the power off, 5 minutes passed and restored the power.
The lamp came on. This says the switch goes to on when the power is restored. Remember mine were short 5 minute tests.
A BIG note.
The reason I am at this video is my switch was stuffed. You could turn it on and off by the app but it did not turn the lamp (power) off.
I came looking for ideas.
When I saw the above video with the switch opened and noticed the relays I though that is it, a relay is stuck, I gave mine a few sharp taps and it worked, the relay is now operating correctly again. (now turn the power on and off as intended.)
I like with the app how I can see how much power is being used by the things plugged into the switch.
This video saved me arguing with Bunnings staff over warranty. (I cant find the receipt)
They cost about 20 dollars which is not going to break the bank if you get one and see if it works for you.
Hey interesting question! I am not sure if these remember their last state or have a default, but I've left the notification in my inbox so when I go back to the workshop I can test that for you.
Personally I don't consider the default software/firmware combo safe - whether it's Arlec, or the more common Tuya (which they might even be based on, I forget). I would definitely say that the ESP and Beken platforms used are great and safe, it's the code on them that is not. I'd always recommend flashing with something like OpenBeken or for ESP's then Tasmota or ESPHome. I've done that with nearly all of mine.
The best ones though are the Athom plugs - they're Chinese, but come pre-flashed with either of those, and all their code is open source! Ref ruclips.net/user/shortso3iGvt1FTDc and ruclips.net/video/YSEezVtnBoA/видео.html
Seems like a big concern. If one has something electrical - say a fan, heater, or a simple light - and forgets this. They then leave for a week, 2 or 3, and the mains power goes off and eventually back on, this seems to mean trouble, as all items turn on and stay on. Lets look at crazy but not impossible examples - one forgets to unplug even one of these smart plugs, and then goes away to a place where there is no signal (bush cabin), or fly's overseas and forgets, and even unimaginable scenarios - becomes sick in hospital for weeks etc etc. Those electrical items may be left on?!!! Where we live sometimes the power resets and temporarily goes off - especially in windy conditions.
@@peterg902 Hey I went and picked up the plug and tested this out - it defaults to "last state", eg if you left it on, when power comes back it'll turn back on. There are settings in the app to set always-on, always-off, etc though!
Thanks for that. Yes, apparently, the Black/White Smart Plug have settings for Off, On, or "Remember last status. If you set this to "off"........when the power cuts out - and then some time later comes on again, the plug starts in an "off" state - regardless of whether a device (e.g. lamp) was on or off. This is good news, as no one wants their lamps, heaters or whatnot to be on for a week or more - especially, if away from home. You will then have to switch the plugs on again using the grid connect -> prior to being able to power on (using their own respective switches) connected lamps / heaters etc .
Great video - thanks for all the info.
Has anyone else noticed that these devices reset/flap at random times - sometimes up to twice a day?
I bought a pack of 4 and all do the same thing. At a random part of the day, or night, you will hear a click, and whatever was powered on via the device is now switched off, and immediately after that, another click as it is switched back on. I have no schedules defined etc and load is around 2 Amps or less. All four devices do this at different times, so I don't think it is environmental.
Any ideas as to what could be causing this, and have others seen this occur?
Oh mate I had sworn mine was doing this but I could never catch it. I have some old crap ones that I know do it from time to time, but that's expected.
I am putting it down to either a firmware issue on the devices, or some sort of power regulation. Where we are power can drop down to 220V, or under 49Hz, usually just for a split second - they probably hate that.
If it's firmware, flashing it with Tasmota or ESPHome might help rule that out, else to rule out the mains voltage you could run it off an online-conversion UPS and see if it does the same thing.
I had some other thought of what could cause it, but I've since forgotten. Maybe worth checking your wifi logs to see if they actually disassociate; if it clicks and then reconnects to wifi it's a whole reboot, else it may just be the relay losing it's latch.
@@PlatimaTinkers
It worked out very well that I had these in my study whilst working from home, so I could see/hear it happening.
Thanks for your ideas.
I'll look into the wifi disassociation and any error logs. I was also going to try and get some tcpdumps to see if anything interesting there as well.
I thought if I had an issue with bad power etc, all four should have flapped at the same time, but this was never the case. I'm not an electrical expert so that could be a wrong assumption on my part. I do have a power strip running from the UPS, so I'll put one of these devices on that and have it feed my PC. That way I'll know if it has restarted if I am not around when it happens.
If the above doesn't show anything, I might look into using different firmware, as you suggest, to rule that out as well. I'll let you know if I find anything.
@@craigreeve1091 Ah yeah okay if you've got multiple on the same circuit that flip at different times, I'd say the power source is not the issue.
Wifi disassoc is definitely an interesting one, I've been meaning to do a tcpdump of a freshie too at some point, as I really suspect there is more data going on than required. Some of mine are on a local Home Assistant, and their WAN traffic is way too high (in the MB's sometimes).
Only go Tasmota or ESPHome if you have something to manage it with! Home Assistant is my choice, but there are heaps!
