Modbus communication between Fronius Symo and Viessmann 333G

Tarvola — Thu, 21 Oct 2021 06:31:42 GMT

Hi,

I have Fronius Symo inverter with Fronius smartmeter and Viessmann 333G heating pump. Is it possible to connect/communicate between Fronius and Viesmann 333G through Modbus? Fronius is using SunSpec Modbu standard.

Hello Tarvola,

Modbus communication is not possible in this regard.

Many greetings
