I have 2 Ikea 5 buttons remotes and they had been working wonderfully.
Now they both show up in the app like there is nothing wrong and also show in the devices section of the IDE as online, but I am getting no activity and they dont seem to be working at all.
That sounds like the symptoms of the battery drain issue that many IKEA buttons are having. They can be working absolutely fine and then eat up a battery in less than a day - so quickly that the battery status often doesn’t get a chance to update.
