Motion lights broke with 2026.1.2 update

I have a couple motion sensing lights using the “Motion-activated Light” blueprint. They’ve been working fine up until the 2026.1.2 update.

Now I can see that the motion sensors and lights still work fine individually in the dashboard, but when motion is detected, the lights are not automatically commanded to on or off.

I tried restoring a backup to 2026.1.1 and that didn’t fix it, so I don’t understand what broke and what to try next.

Update: Never mind.

I tried editing one of the automations and when I saved it, both suddenly started working again. They stayed working after I upgraded back to 2026.1.2 again.

So I have no idea why it broke, but it definitely was not working for a while there. And I have no idea why editing one of the automations would fix both.

Thanks for any thoughts on the topic.

Kind of random and never explained andoccasionally reported
