After upgrading to 0.1.13 my battery devices are all unavailable. Waited about 2 hours after 2 restarts, but they stay unavailable. After reverting snapshot to 0.1.10 all is well again.
can only say I see all batteries as before. Not much help, maybe you can wake them up manually?
I experienced the same behavior for both 0.1.12 and 0.1.13. The battery device shows “node ready”, but two associated entities are greyed out. The battery level entity does show a value. Restoring a snapshot of 0.1.10 restores normal behavior. This does not appear to be related to HA core updates.
