...for every rule I've got with a Cron string as a trigger, mostly changing colors of Zigbee RGBW strips once a minute. Here's one of 'em:
Certainly nothing there that should (or did, these have been working fine for months) cause the Cron trigger to run for 150 seconds (which creates a problem on a once-a-minute rule). Any ideas?
EDIT: on the off chance that this is related to some Zigbee issues I've been having on the same hub (mostly just building a new network in a new house), I moved all the "Cron" calls to another hub, having them set virtual switches on the "production" hub which the rules trigger on, instead of a "Periodic" trigger.
So far, both the device and app stats on both hubs are looking good.
