How it connects
Franzl reads this device through the Home Assistant integration stiebel_eltron. If your device is already set up there, Franzl finds it automatically.
Setup
The connection runs through Home Assistant: either the built-in stiebel_eltron integration (covers only a few values) or, recommended, the HACS integration stiebel_eltron_isg, which exposes more values. Both talk to your ISG over Modbus.
Requirements
- An ISG plus (not the base ISG-web) for SG-Ready control over Modbus
- In the ISG SERVICEWELT, set the signal source to "Modbus" under Energy Management
- ISG firmware ≥ 12.0
