My intention was to create two simple ESP32/AHT20 temperature sensing devices, and experiment with ESP-NOW capabilities. My play was to get the two devices working, then gradually add the specific communication protocols.
Device#1: initiated in ESPHome, and added appropriate lines of sensor code. Device#1 operated perfectly, reporting temperature and humidity.
Device#2: prepared exactly the same way, remains ‘offline’.
I eventually deleted both devices and started again. Now both devices show ‘offline’. Yesterday, I was happily editing code and updating Device#1 through wifi. Today – nothing. Any thoughts?
I’ve encountered several other problems, but probably should attack these one at a time.
