I installed five LZW36 combined fan and dimmer switches over the weekend. Mostly things went well but I did run into an issue that, for one switch, I am still contending with. Help is appreciated. I am using Samsung SmartThings for the moment (but probably not for long).
To lay the groundwork here, I have both device handlers installed. I have the 2020-05-18 version of the “Inovelli Fan + Light LZW36” handler and the 2018 version of the “Switch Level Child Device” handler.
My issue revolves around the devices I get when I add the switches to my SmartThings-managed Z-Wave network. 2 of the 5 switches worked exactly right the first time - I got the parent device for the fan and the light, and the 2 child devices, one for the fan and one for the light. For 2 of the switches, I had to go through multiple add/exclude cycles to get the right devices. Sometimes I would get the parent device and the light device (no fan-only child). One time I got only the parent (no light-only, no fan-only). And one time, oddly, I got four devices (one working parent, one identical but not-working parent, and two working children. I just hid the non-working parent and kept it).
But my last switch is my problem child. It has been through three add/exclude cycles so far and every time the results are the same - I get only the parent device and the light-only child. No fan device. The parent and the light-only child work as expected. This switch should have excellent connectivity, it shares a 2-gang box with an Inovelli LZW31-SN dimmer switch that works well. The LZW31-SN has zero hops to the hub. Besides the add/exclude cycles, I have also tried Z-Wave network repair utility but no change there.
Is there any way to add the child fan-only device that’s missing? If not, any other ideas? Thanks!
