OK, so I’m not sure if this exists, but I haven’t been able to find it and it’s a very simple thing.
I am looking for a (very) small, wireless light (so yes, it operates on batteries), which connects to Homey. I want to use this to indicate the current state of a device (on or off). I need this in another room than Homey, so I can’t use the led-ring.
Colors are not required (simply on/off is sufficiënt), but would of course add more options.
Extra points if the thing is really small.
I had something like this in mind (but this cannot be connected to Homey)
