Per-station battery monitoring device (Homey class battery). Name: Batteriemonitor / Battery monitor.

Linked to the HKW; updated from full battery RSCP readouts and live SoC/power.

measure_temperature_min / measure_temperature_max Min / max cell temperature
measure_voltage Battery voltage
measure_dcbcount Number of DCB modules
device_name Battery name from station

Notes

  • Temperature sensors: stations often have many sensors — min, max, and average are exposed.
  • Capacity can be wrong from the station; override on the HKW battery settings if needed.
  • Useful for Homey Energy battery graphs together with the Grid meter.
