Battery Sensors

For each battery driven device sensor the following attributes are available Battery Voltage, Battery Percentage and Battery Level. From conversations with Wiser technical support they recommend changing the batteries for any TRV when it reaches battery voltage of "26" or OneThird battery level. Given that RoomStats do not need to drive a valve, their battery levels can be lower.

An obvious ideal candidate for a Home Assistant automation to remind you to change the batteries :-)

Note : If you power cycle your HomeHub, with more than a minute or so when it is off, we've noticed that the devices will not have the battery info for a short period of time (maybe 30mins to 1hr) , just wait and the battery values will appear.
