Lesson25- how to send alert message to Whatsapp by KC868-A4 A8 (ESP32)

[der metty]

Okay, thanks.

I have just opened one, theres an IC labeled "PIC16P630" and "0819VHR".


EDIT:

Found another 433MHz Remote that isnt suitable for my purpose but your Code identified the adress.
Guess I'll have to buy a new one.
Any advice on how to identify a compatible one before buying it?

Thanks for your help!
