Suddenly stopped working

Hey there!
From one day to the other, I cannot control my bathroom lights anymore. Did anything change?

No, the blueprint did not change and I believe they don't auto update anyway (not even sure about that tbh, maybe that changed at some point but I don't think so).
Perhaps your remote is out of batteries or it just dropped off the network for some unknown reason. Try to find the device in HA and click 'reconfigure', that sometimes does the trick.
