I recently had an LZW30 switch installed, firmware v1.20, being controlled by a Hubitat.
A little bit of background: we had a mechanical timer in the basement that operated the lights to the front of our house. There was also a manual switch near our front door, that also operated the same lights. Once the mechanical timer kicked in, the manual switch would stop functioning until the timer turned the lights off (meaning we couldn’t turn the lights off at night). If the timer wasn’t on, the lights could be manually controlled with the switch. I wanted full control over this.
There are 9 total lights outside. 5 under an overhang, 2 attached to the brick of our house, and a light post on each side of our front yard.
We had an electrician remove the mechanical timer in the basement, and essentially remove the “three-way” that was being used, making the switch near the front door the only device to operate the front lights. When he was finished, and our LZW30 switch was installed near our front door, I tested it to make sure the lights went on. It was during the day, and I thought all of the lights went on and off as intended. Except…I didn’t notice that the light post bulbs on the side of the yard no longer went on, until that night.
The electrician has been back numerous times and cannot find any faults of his own (though if it’s on him, he will keep looking and repair). He has tested voltage levels at each light post, and there isn’t any voltage at all.
I checked the bulbs from each light post, and one is an LED, the other is a standard bulb. All of these worked prior to this work being done.
Is it possible that the switch is the cause of this? Or is that unlikely since all of the other 7 lights are working properly?
