We’ve just moved out of daylight savings time (BST, UTC+1) back to our normal timezone (GMT, UTC). At 2am the clocks went back, so we effectively had 1am twice.
I’ve just been woken up at 2.15am to find the lights in the house turned on (many of our ZigBee and Tasmota bulbs are configured to do this if they lose connection) and all our esphome devices LEDS flashing. Home Assistant has crashed and is completely unreachable!
I’ve powercycled the raspberry pi and it’s all come back okay. We have some automations triggered with cron-style notation to run every “/10” minutes. Looking in the logbook I can see these time-triggered automations were running repeatedly (almost every second) around 1.15am.
I want to go back to sleep, but I’ll do more troubleshooting in the morning. Has anyone else seen similar?
