M5Stack PoEsp32 for Faikin?

[BeFygo]

Hi,

Would it be possible to wire the uart from the M5Stack PoEsp32 to a s21 or A50X port and run Faikin?

The m5stack would get it's power from POE.

Probably. It is just serial.

The main issue is that S21 uses 5V signalling, and 3.3V does not quite work on all models, so a level convertor may be needed.
