I have in mind to make a tiny remote control, compatible with home assistant, just with buttons, but if it worked with voice like I think the XIAO MG24 Sense possibly could do, that would be great too.
I originally had planned on trying to make a zigbee remote until I saw the XIAO MG24 Sense and thought even though I have been avoiding matter so far in my home assistant setup, maybe it’s time to learn about it too. I currently have XIAO MG24 Sense, and XIAO ESP32-C6 in my cart, but have no idea where to start.
Is it possible to run either of these, or maybe some other zigbee or matter chip off a coin battery like a CR2032? I downloaded the Arduino IDE, but have never done anything with esp32 other than flash them for HA bluetooth proxy. what buttons should I buy? what else would be helpful to get me started with this project?
Hi there,
SO I can only speak on the Xiao ESP32C6 and point you to the WiKi and the examples included in the Arduino_IDE. They all work, Albeit it is important to know how your dev environment is setup and how to move around 
, above that is how much you want to learn…
Also a pretty cool online resource, that is pretty slick in it’s own method,
The ESP-NOW website , you pick your ESP C3, C6 or S3 is supported If I recall correctly. If you want a switch a light or a digital control. You put in the GPIO pin numbers . and Click next and It Flashes the code to it , I can go to Alexa, HA, or ESPHome and it finds the new device.
READ the WIKI’s for the Xiao Stuff come back and ask more questions. Others will chime in also, a lot of smart folks on here willing to help and have built stuff with both so STart with the basics, get a few blink programs going on the Xiao’s compiling and flashing comfortably
look at the MCU’s Wiki’s see what the buttons and connections do. Start there and GO!
