HI all,
Upfront I apologise if this has totally been covered by someone, I have read so much on this topic but seem to not find a solution.
In short, I have flashed a Sonoff Touch [(https://sonoff.itead.cc/en/products/residential/sonoff-t1)], with my own ESP8266 code. I did NOT use Tasmota. The Touch is connected to the wifi, and I can even publish MQTT topics to it, and it responds. (I can make all three the relays). However, the physical buttons on the touch does not work. So my challenge is not so much OH, but in the ESP8266 code.
When I say my own code, I mean code I have used on other ESP8266’s and ESP32’s I have around the house. Mostly sprinklers, lights via relays and such. The Sonoff touch is the first time I have had to publish MQTT topic from the “thing”.
I have the following setup.
OpenHAB 2.4
MQTT v1 (but have the v2 addon for all my other ESP’s to work)
Here is a copy of my items entries:
Blockquote
Switch kitchenswitch1 “Kitchen Switch1” (grp_kitchen, grp_houselights) [ “Lighting” ] {mqtt=“>[broker:openhab/in/kitchen:command:ON:switch1ON],>[broker:openhab/in/kitchen:command:OFF:switch1OFF]”}
Switch kitchenswitch2 “Kitchen Switch2” (grp_kitchen, grp_houselights) [ “Lighting” ] {mqtt=“>[broker:openhab/in/kitchen:command:ON:switch2ON],>[broker:openhab/in/kitchen:command:OFF:switch2OFF]”}
Switch kitchenswitch3 “Kitchen Switch3” (grp_kitchen, grp_houselights) [ “Lighting” ] {mqtt=“>[broker:openhab/in/kitchen:command:ON:switch3ON],>[broker:openhab/in/kitchen:command:OFF:switch3OFF]”}
Here is my ESP8266 code.

You may note the commented part in the middle, it was my attempt to get this to work. BUt that code only made button1 come on and stay on, and the MQTT status was basically looping all the time.
According to this site link the GPIO’s are the way I declared them, but I may be wrong in the interpretation.
I would really appreciate some guidance. My coding skills are near to non-existant. 
THank you in advance.
