What type of bulb do you have connected to the switch (LED, CFL, Halogen, etc)?
I have 5 total - 1 LED and 4 incandescent (R20). My builder installed 5 incandescent bulbs. One burnt out and I replaced it with an LED can light.
What is the approximate Load Wattage?
When I first installed the LZW31-SN, the log on my Hubitat hub showed about 180W total when on at max brightness. Now (see notes below), after things are working, it shows about 156W
Bonus Points: Make/Model of your bulb(s)?
Unbranded incandescent and ecosmart 50W-equivalent soft white dimmable R20
Switch Setup (ie: Single-Pole, 3-Way, 4-Way, etc)?
4-way. One LZW31-SN replaced one out of the 3 total dumb switches.
AC Power Type: Neutral or Non-Neutral Setup?
- I have not removed any heatsink tabs.
- In your wiring docs, my setup matches the first diagram under 4-WAY INSTALLATION (DUMB SWITCH) NEUTRAL WIRE REQUIRED at the top of page 8, except the load is 5xR20 ceiling can lights instead of one.
- initially my Hubitat logs showed ~180W load, just using it as an on-off switch (i.e. max brightness)
- it switched off automatically after a few seconds, but it had something to do with the permutations of other switches; it wasn’t always predictable. I never had to wait more than 5-10 seconds for this to happen.
- I followed the forum suggestions to set the max brightness to 80% and then things seemed stable. I flipped the other switches and things worked as expected.
- Then I increased to 82%, 85%, 95% and then the max value of 99. No issues! It’s been stable in the past week since I received and installed this.
- Power consumption now shows ~ 159W max, with 99 as the max dimmer value. I think the lights are slightly dimmed (i.e. not as bright as they were before), but I’m not sure without being able to return to the previous state easily (when I first installed the switch).
I suspect there’s some bug involving the first time setting of the dimmer max brightness. Maybe the internal factory default state is not whatever the value of 99 maps to and that somehow contributes to this?
Perhaps I should try a factory reset to try and reproduce this?
