to my knowledge this is the first working integration with espmesh/painlessmesh which is a mesh protocol pretty sure everyone here know what that is. it works with esp32s and esp8266s and i decided to make a program for it because of how cheaply you can buy esps online and mak emy own devices.
The first picture is what i have working right now its a simple relay+microcontroler combo that i bought of of aliexpress for about 2 dollars and the second is a esp8266 and a esp32 that act as a bridge between hubitat and painlessmesh.
right now its just one way communication but i think it will be pretty easy for me to add the ability to talk both ways
