Summary

Fixes the zigbee battery value_template override for WSDCGQ12LM sensors that report battery: 0 due to a firmware quirk.

The original fix in c515a6b used homeassistant.sensor_battery.value_template but the correct key is homeassistant.battery.value_template - the override key must match the entity type in the MQTT discovery topic path (homeassistant/sensor/<device>/battery/config).

Changes

  • Changed sensor_battery → battery in the homeassistant override config for all three affected sensors

Test plan

  • Verified MQTT discovery message contains the new value_template: 
    mosquitto_sub -h localhost -t 'homeassistant/sensor/0x54ef441000a547bd/battery/config' -C 1 | jq .value_template
"{{ (((value_json.voltage | float) - 2100) / 9) | round(0) | int | min(100) | max(0) }}"
  • Wait for sensors to report (~30 min intervals) and verify battery shows calculated values (~62-74%)

The homeassistant override key should match the entity type in the
MQTT discovery topic path. For battery sensors, the topic is
homeassistant/sensor/<device>/battery/config, so the key should be
"battery" not "sensor_battery".
