 The default is to also provide a battery health percentage calculation by dividing `energy_full` by `energy_full_design`. This can be disabled by setting `BATTERY_HEALTH` to `0` in your `docker-compose.yaml`. 
 Similiarly, an estimate of time remaining on battery (in hours) is calculated by dividing `energy_now` by `power_now`. This can be disabled by setting `TIME_REMAINING` to `0` in your `docker-compose.yaml`.

+You can monitor the status of the AC adapter (online or offline) by setting `AC_ADAPTER` to `1`. This is disabled by default.
