Inspired by the very pupular topic Weishaupt Heatpump integration via modbus - Share your Projects! - Home Assistant Community (home-assistant.io), I have decided to share my Weishaupt Heatpump (WWP L9 ID) setup as well.
Hardware
- Weishaupt LWPM 410, ~150€
- RS485 Konverter Bus Adapter Seriell USB, ~3€
Config
-
heatpump config
- Menu → Config → Network: Select modbus, baudrate 9600 and slave address 1 (if only device)
- Optional for Smart Grid: Menü + Enter → Config → Anlage → Flexeingang → N1/J5-ID1+2 digital: Smart Grid
-

Based on this I can do pretty much everything 
My main use cases are:
- Smart Grid based on Solar energy produced / forecast (incl. thermal desinfection)
- Change operation mode
- Monitor energy consumption of heatpump
- Calc JAZ
- Monitor temperatures around the heatpump (watertemp, room temp, …)
