Question: ESPNow button device Wake-up for trigger (in homeassistant)

[FGarridoV]

Hello @iphong.

I was checking your repo and it is one the most similar ones that achieves what I want. So, I thought maybe you can guide me towards the solution I am looking for.

I am looking something similar as you have in your repo with the motion sensor. Specifically, I want one ESP device with a button connected. My idea is to have this device sleeping and wake up only when the button is pressed, send data by espnow, and then send it to sleep again. Your implementation about the motion sensor is quite similar, but I am wondering how to send the device to sleep. (All of this using esphome)

Will be nice if you can guide me how to add this functionality. And sorry if this question is too basic (I am really new here). Thank you in advance, Francisco
