Product name
Nuki Door Sensor & Smart Lock (Pro and non-Pro) 4th gen
Summary
Expose the Door Sensor battery remaining percentage state over the Smart Lock’s MQTT connection.
Expose the Door Sensor battery remaining percentage state in the Nuki app.
Features
Similar to feature request Expose Door Sensor state over Matter, this request is to expose additional states over MQTT for Nuki Door Sensor (also as first requested in Door Sensor - Battery Level And Firmware Version Missing In MQTT), specifically the battery percentage remaining value.
Also nice to have is the door sensor battery remaining percentage value in the app on the Door Sensor page.
A nice to have would be the door sensor firmware version state to also be exposed to MQTT.
Reason
Without the percentage battery remaining, it is difficult to determine actual amount of battery left to help determine when the battery needs to be replaced, or at least to have pare batteries ready to replace. Both the Nuki app and MQTT only give a reading such as OK
or doorsensorBatteryCritical = false
which isn’t very useful whereas the lock giving a value for battery remaining is much more beneficial.
Examples
The battery remaining percentage state in mqtt would enable users to create notification automations to replace the battery at a user configurable threshold.
The battery remaining percentage state in the Nuki app would similarly allow users to monitor battery state and be better informed when the battery is low/threshold of their choosing to be ready to replace the battery.
