The problem with your design is that the physical switch state wont change if you turn on from switch and turn off from alexa. It would be better to use push or touch buttons here. You van also try adding in a raspberry pi with home assistant to add a cluster of such nodemcu subsystem in the entire house

To connect more lamps you need a hub or server, por example the program home assitant in raspberry pi, and the custom firmware tasmota, and devices with esp8266 like sonoff to control outputs for control infinite lamps

Hi from Czechia, thx for videos..... But this is exactly what I need as a time relay, to automatically turn on different channels at a set time? Can you recommend software for this? Thanks
Great video👍 I had a question wrt the Channel Relay, is there a specific one required or any relay is fine. Since i have a relay module lying around but whenever i tried it doesn't work. Your thoughts.
hello friend, can you help me with something. when I do the project it works perfect. but when I mount it in my room that I make all the connections the manual function does not work for me. It is possible that it is because the cables that go from the ESP8266 to the push button I am passing them next to the alternating current cables 120 AC
does it trigger the relay if there is no internet in a loop ? which happens to me while using Blynk, if modem is off, the relay will trigger every 1 minute.
hey brother, thanks a lot for such a brief and awesome informative video, i have few questions though, will the sinric pro be running for long years or it may be closed. for how long we could use the app? what if he just shut downs itself? like app closed
Giving switching control with nodemcu had lot of mal function. Relay Automatically turns on or off if some switch turns on from other room which means does not has physically connection to nodemcu Junction. Sometime can't able to communicate with nodemcu needs to restart complete. It's really difficult to remove from Junction and reset. Note : you can't find these issues with demo session , you need to test real-time which means need to connect in home switch board or Junction and where you using regularly.
You wire them up so they fail in a state where the light is on so a conventional switch can now control them. Actual people who do this thing think of that naturally plebs like you just sit and wonder.
@@tylermcnally8232 considering myself as a pleb, trying to implement this by learning, do you care to elaborate the "wire them up so they fail in a state where the light is on" thing?
I couldn’t get to set my esp8266 and esp32 running in my Arduino ide even after installing Python 2.7.3 and pyserial from adafruit. I have downloaded the drivers and installed the board in Arduino ide. The port is “com 28” and I think I used “nodemcu 1.0 module 12E” for esp8266 or there about! ( I am using CP2102 chip) The device manager shown that the hardware was properly installed and ready to use. If I try to open the serial monitor in Arduino it will never open, instead I will see “error com port 28 busy” If I upload code on the boards it pops out bunch of errors among which is “error opening serial port” or something like that. I am frustrated, I need help please!
Please I really need help with this connection my presentation is on tuesday... I found out that after connecting everything all components read well except the diodes, it's like it's shorted.
