ESP8266 Alexa RF Bridge Code help please?

s200bym · December 4, 2021, 3:59pm

Hi,

I have made myself an Alexa RF Bridge using an ESP8266 so I can control my Christmas lights with 433mhz RF plugs. I have also incorporated a touch switch so I can manually switch the lights on and off if Alexa doesn't play ball.

I have written some code for this that controls all the RF plugs at the same time, this works as it should and acts as one device.

I have modified the code and separated the outside lights and inside lights on different RF signals so Alexa can control them independently, so it now acts as two devices. While this works fine with Alexa, the touch button is randomly not working and status LED's are out of sync (green off and red on etc). The ESP 8266 then resets. The only difference between the 2 codes below is that I have added more devices and 2 separate RF transmit codes for inside and outside. The ESP 8266 doesn't reset if I just use Alexa and do not touch the switch.

Below are the 2 pieces of code, the first being just 1 device and working fine and the second having the extra devices added and not working properly.

Many Thanks,

Looking further into it, it seems that the "All Christmas Lights" both Alexa and Touch switch code is the problem. I can't see any obvious issues though.
