First the Obligatory:
Smart Switch: lzw30-sn (Red On/Off)
Firmware: v1.20
Secondary Switch: dumb
Load: 8 dumb LED bulbs in can lights
Hub: Hubitat (using latest driver from Inovelli)
My current setup is partially working. If the dumb switch is in the “off” position, the smart switch works exactly as expected. However, things get unpredictable when the dumb switch is in the “on” position. See the attached gifs. In addition to what you see in the gif. When I turn it off, it’ll turn itself back on. I usually have to turn it off 3 times before it’ll stay off. I’ve tried switching the load type from “default” to “Special”. This doesn’t appear to make a difference.
Seriously all LEDs have a mind of their own. It may work normal now with the LEDs, but you might have to find another brand of LEDs to make it work normal. At least it’s not wiring or switch.
