At the moment I often notice that HA does not always perform the tasks it is supposed to do at the correct time. Sometimes the times are shifted by a few minutes, sometimes they are not performed at all. I automate my thermostats and lamps with schedy and simple scheduler. in 80% of the cases the automation works, in 20% of the cases i have a cold bathroom in the morning. what could be the reason, how could i best find the error?
If something is supposed to happen at a certain time, such as a light turning on at 08:00, the first thing I would do is check the log to confirm the automation triggered at 08:00.
If it did, then I would check why the command to turn on the light failed to reach it.
If it did not, then I would check the automation’s logic (its trigger, conditions, and any templates in the action) to determine if there are any situations where it might fail to activate the light at the scheduled time.
