Thanks for the answer. I meant that Mysensors has ESP32 support but only in terms of WIFI. It supports e.g. stm32 with ENC or W5500 modules - and the question is whether and how to add ESP32 support with LAN8720 module. I am not considering using ESPHOME or MQTT - I want to have native communication with the controller that implements my control schemes on its side. I try to program KC868-A16 but it does not matter - the question is whether such support can be added in a simple way.
Over 4 years on, and my node ran continuously sending 4 messages every 5 minutes.
It's 700mAh LiFePo4 battery voltage dropped from initial 3.45V to 3.24V, according to LiFePo4 voltge/SoC tables It's just under 40% left.
700*60% = 420mAh. 100 mAH per year. using library 2.40 and blob message I could cut usage to ~25mAh/year, not bad
