Question abut sending values from mqtt-topic to fronius GEN24 inverter (emulate an fronius smartmeter modbus tcp in sunspec compatible format)

[rICTx-T1D]

Hi folks,

Iam new on topic modbus and I have the following homelab projekt:

• my Valiant heatpump measure energy consumption in real power and total energy (in kWh). This values I grap over ebusd to mqtt topic.
• the mqtt topic I read to openhab and visualize it. working fine.
• now my inverter "fronius Gen24+" can start some rules to improve my self-usage-rate. But for this,, the inverter must know, how much energy use the heatpump at realtime.
• in fronius, I can add a meter from type "Fronius smartmeter modbus tcp", so I looking forward to create a bridge from mqtt and present it as a modbus tcp server.

Can you give me more assist, how to configure it.... Is it possible in this direction (MQTT -> send to -> ModBus tcp server)?

Ciao
