I have several of these but have a problem with one installed on my driveway. It is only 10 feet from 2 other Lightify bulbs, but it seems to not respond to ST commands. I switched bulbs and it seems to be the location, not the bulb. Aren’t these things supposed to mesh, so they can be farther away from the hub? It is on the far corner of my garage. A bulb on the other side of the driveway works fine, as does one on the side of the garage.
