Data stale after Home Assistant update #483
Description
Similar to #353 I have the problem that NUT reports "Data stale" after I have done a home assistant core update.
After a restart of the addon the problem always resolves itself.
Is there maybe on option to detect HA Core updates and auto restart the addon?
