I believe I’m having the problem described in this thread. I installed the LWZ36 in January and it worked perfectly for months. About a month ago, it stopped working reliably. The switch always reports to SmartThings that the state has changed, but the fan doesn’t respond much of the time. Rebooting the switch via the air gap would solve the problem temporarily, usually the rest of the day. More recently (perhaps after a power outage), it has completely stopped working, as if it’s lost pairing to the canopy module. I’ve attempted to re-pair them without success (switch pulses cyan for a while, then red; fan light continues pulsing).
SmartThings reports my switch has firmware version 1.34. I do not have a Windows PC nor z-wave stick with which to update it.
- What Fan (Make/Model) do you have? This is important.
- I believe it is this one
- Does your fan have pull-chains or is it remote operated? (If pull-chain, make sure to set it to high)
- remote operated
- What wiring schematic are you following? Schematics can be found here: LZW36 Wiring Schematics – NOTE: Please let us know if you have any alternate wiring
- I replaced an existing wireless remote control module that looked very similar to the Inovelli one. I used the existing wiring. I believe it is the “power into switch” diagram.
- How far from the canopy module is your switch?
- 20’, nearly line of sight but there is the edge of a door frame in the way
- What is the estimated temperature in your house?
- AC is set to 74. Today is the hottest day so far this year and the canopy measures 90°F. I haven’t observed a correlation between function and temperature.
- Can you give pics of the canopy installation (show how it’s sitting in the canopy and how it’s wired?
- sorry, I don’t have any pics of inside the canopy and opening it is a chore
- Do you have any access points near the fan?
- the nearest access point is about 2’ from the switch, thus over 20’ from the fan
- Would you consider your 2.4 GHz network large or overworked?
- I have two 2.4GHz APs in my network, but very few of my devices use 2.4GHz.
Any ideas?
