I recently migrated from a RPI3 to a much faster NUC and am now running Homeassistant in Docker (something everyone should do :-))
Everything works fine, except the triggering of automations based on time. See an example below. I cannot figure out what is wrong, so any guidance would be much appreciated!
I don’t know exactly how docker changes things (I don’t use that), but typically this kind of problem (automations not triggering at the specified time) is caused by HA and the underlying environment (OS, whatever) not being set to the same timezone. Although, yours is a periodic trigger, so I don’t know if that might be an issue here. At least it’s worth checking.
If you manually trigger the automation does the action run correctly? Also, is the automation on? If so, it would indeed seem to be the trigger that’s the problem.
