My issues with Konnected began when my wife started complaining that she could no longer use her remote on the garage door. The Konnected device is in our laundry room, which is on the other side of the wall from our garage. We have an older garage door opener, which apparently operates somewhere ~300MHz. There shouldn't be any interference caused by wifi at 2.4GHz (I don't have a 5GHz network), but a colleague suggested that I try powering the ESP8266 via its USB port to rule out the power supply as a factor. I tried that, and the interference continued. I then found a firmware update on the Konnected GitHub page, and flashed that to the unit. Now, not only do I still have the interference, but the doors in every zone appear to be open now, even when they're closed.
