I have automations when homeassistant started event is triggered, I see that my automation is triggered multiple times per day, I search in the logbook and see that the started event is triggered multiple times per day, anyone have an explantion?
Thx.
Have you been restarting home assistant?
If not, that’s not normal. This trigger:
trigger:
- event: start
platform: homeassistant
Should only ever happen when home assistant is restarted.
Is your system crashing?
HA was not restarted, but I checked now a sensor with HA uptime and effectively it seems that the system is crashing 
I found this in the supervisor:
21-08-17 12:16:09 ERROR (MainThread) [supervisor.misc.tasks] Watchdog found a problem with Home Assistant API!
21-08-17 12:16:09 INFO (SyncWorker_3) [supervisor.docker.interface] Restarting homeassistant/raspberrypi3-homeassistant
