I had a small problem with a samsung multi-sensor in my garage: didn't activate my lamps (Caseta).
Fine, change the battery and let's see...
Battery changed: nothing changed
So I checked my tradfri outlet who is acting as a repeater. The outlet was there bus not reacting to any command (ON/OFF). So I checked the others (3 more): same pattern for all of them !
I unplugged them for 5 seconds, replugged and they all are behaving normally (and my samsung sensors behaves normally too, btw).
Any idea why all those Tradfri "suddenly" stopped ? I have no idea when they stopped and if the problem was simultaneous or over the time.
And I have a no problem with my hub (except that I reboot it too often, but don't want deconstruct everything for now) and my caseta lamps (mostly activated with samsung multi-sensor) .
I had this happen to my all of my Trådfri Repeaters about 1 week ago, I tracked it down to a minor power surge in my electric grid that I myself caused. I didn't notice at first that it was the repeaters that were acting up since they don't have anything else they need to do... It was after that I wrote my "Presence" drivers for those repeaters and the plugs.
Fine, I'll monitor this. As I remember, there was an thunderstorm around here and I saw the lights of my desk flickering for just a few mS. Good to know.
Related question: shouldn't zigbee repeaters (Tradfri or others) rebuild the mesh in the event of a ("micro") power failure?
