I have a few Ikea Tradfri shortcut buttons. I’ve noticed that their battery levels in HA are… inaccurate at best. I googled around a bit and saw that there’s been some work to fix related issues (including two different ways of measuring battery level, based on the button’s firmware version).
I think I have the latest firmware, but one of my buttons is stuck at 2% battery, even with a fresh one in there.
Has anyone else ran into these issues? Any ideas on how to fix it? It’s a bit annoying just guessing when the battery will die.
