I only made this user to share this 🤣 Thanks all for the inspiration.
Exactly as BrettC suggest, I made this in the weekend for my deye I have shared it with some hundreds other danish deye owners and waiting for more feedback.
The adresses i use is matching my 12kW 3 phase, low voltage hybrid deye inverter. I seems for me that the modbus adresses does not match your sunsync inverters(deye inverters).
