One of the oldest pieces of hardware I use is a hue bulb. It has a simple rule and is switched on at sundown. This has been working for almost three years without a single problem. In fact, there are two bulbs switched on in that fashion.
Since two weeks one of the bulbs is going on/off at random times. The other bulb behaves like it should be. I didn’t tinker with my setup since six weeks or something like that, so I don’t think I implemented an error in some new rules.
Is this how a hue bulb fails? Do I need to update something? It’s just this one bulb going on/off at random times, with no corresponding rule triggered. Does anyone know what might cause this?
