Batteries die before low battery level entity triggered #26

Closed tetsuo13 closed 7 months ago

tetsuo13 commented 1 year ago

Low battery notification added in #20 doesn't appear to be reliable -- in fact I've never received a notification even though several batteries have since been replaced. It relies on using the "_low_battery_level" entity provided by the Z-Wave devices however it appears that the battery dies before the device identifies it as low. For example, the front door sensor died at 62% battery level.

Use a different approach to identifying low batteries. Something that would allow setting a different threshold per device would be nice.

A list of devices that have experienced low battery levels that never triggered their respective "low battery level" entities:

Device Min Battery Level Notes
Ecolink Door & Window Sensor 62% --
First Alert Smoke & CO Alarm 78% Will stay at 78% for several days. The device will start chirping of low battery as soon as it drops to 77% (typically early morning hours when everyone's asleep), even though the low battery level sensor isn't triggered.

Merged the change for the smoke alarms since I was able to monitor their levels when they depleted enough to start chirping. Haven't been able to notice it with the Ecolink sensors yet. Will create additional PRs as I come across other devices.
