I have 3, 20 seconds for devices that have automations on them to turn on other lights like shower fan turns on with shower light. This one has 4 devices. Then I have a 3 minute and a 5 minute. I noticed the 5 minute was often running at same time as 3 minute so I just changed it to trigger 2 minutes after the 3 minute. This has helped. Basically I split the remaining devices between these two putting the less used switches in the 5 minute.
