Modbus server via the included wifi module for the new H1-Gen2-WL and H3 Smart models
Hi

I saw this video showing that it is now a modbus server on the newer inverters.
https://www.youtube.com/watch?v=q8A32xMifmA

I tried using my H3 Smart 15kW but get this error:

changed to Error reading registers. Type: RegisterType.HOLDING; start: 31000; count: 91; slave: 247 from tcp://IP_ADDRESS:502: Modbus Error: [Input/Output] Modbus Error: [Invalid Message] No response received, expected at least 8 bytes (0 received)

Master : 1.30 Slave : 1.00 Manager : 1.18

Has anyone had any luck? Firmware version or some thing needs to be enabled?

That’s my video. Does your inverter have an integrated data logger or a plug in module?

It's got the integrated datalogger (Type: WL-H3-G2).
