Add an attribute called “Battery Changed Date” to all ZHA/ZWAVE battery operated device along with an event “Set Battery Changed”. This would give an estimate on how long battery lasts on each device.
Functionality is straight forward:
On pairing the device the battery changed date is set to today
Service “Set Battery Changed” will take two parameters entity_id and custom_date(optional,default to today)
Yes I know. I use customisation to add custom field/attribute to each device.
The request is to make the functionality default. I have approx 40 battery operated devices (motion sensors, temp/humid sensors, door sensors etc). It would be nice if we could make this a default system capability not having to use input_helpers or customisation…
