Currently with the Scheduler Helper there’s a service that allows you to restart the scheduler without the need to restart HA: schedule.reload
Google calendars update in HA every 15 minutes, so if I’m working on something using google calendars (like my smart dumb boiler project) and wish to test it, then I have to wait 15 minutes between changes to see if it’s working.
It can turn a 5 minute job into hours of testing to get working right.
(not an exaggeration. It’s literally taken me an afternoon to do some changes in the past)
The only way I found to force it to update faster is to reset HA.
Aligning the calendar to have a reload service would be ideal.
