I have been using a hue wireless dimmer next to the bed for maybe almost a year now and it was working fine for the longest time. There's the occasional disconnect then I'd re-pair it back to the hub.
Recently, it's been disconnecting almost every day, or maybe even after a few hours of re-pairing. I've been scratching my head trying to figure out what was new in my setup and just realized that I had swapped wireless phone charger with my wife.
I initially been using the horizontal version and then switched over to the slanted type. I'm now testing if going back to my horizontal charger will bring back functionality to my hue dimmer.
For reference.
Old charger.
New charger.
