What frequency does the wall switch communicate on? Could these problems (especially the intermittent ones) be from local radio interference?
The reason I wonder is we had an issue once with LED greenhouse bulbs next door (over 100 ft away), causing enough interference that any TV channels in the 200 MHz range became unwatchable whenever the bulbs turned on.
Perhaps there are some cheap LED or fluorescent bulbs nearby that were poorly designed or are going bad.
I thought this was in the 2.4g range, not 100%. However I will say I haven’t had a single miss on my fan switch. It turns on and off each night with a simple routine from HE RM. the light in the fan does exhibit brightness to dim when the washer is running, but so do most of my LEDs and not contributing it to the fan switch.
For documentation purposes, I want to mention that I had to air-gap one of my LZW36’s twice yesterday because it stopped communicating with the canopy module. All of my LZW36’s have been running the short-lived v1.34 firmware since this disconnect problem was first discovered, and everything has been bulletproof up until yesterday.
I spent a little quality time in HomeAssistant J-Wave JS to MQTT this morning, updating the firmware on all of them to the latest v1.36 just to rule that out. I also updated my LZW30-SN’s to the latest v1.22, since many of them still had the factory firmware load on them. Let’s see if it disconnects again in a few years…
I’ve posted in this thread a handful of times… I wanted to loop back to say that both of my Red Series fan/light switches have worked flawlessly for probably 6 months. In that time, inside temps have probably stayed in a 10 degree range while outside temps have changed drastically. No RF devices have been added or removed in that time. I’ve made no changes to the circuits those switches are on, that I can remember.
It’s just as mysterious to me why they work fine now as it was why they weren’t working before, but I’m pleased they’re working.
Completely separate issue. This issue is a disconnect between the switch and the canopy module so when you press the button to turn on/off the light or fan, nothing happens.
If yours is turning off exactly at 2hrs 10 min I’d be looking into an automation or something that could be sending it the off command. If the time varies, then it could be just about anything and you’d need more troubleshooting.
It is summer time and getting hotter in my area. I have noticed that my connection between the switch and the canopy module is getting worse again. Last night I had to keep trying to turn the light off for about 5 minutes before the canopy actually received the signal. I don’t know if it is actually related to the heat though. It seems like it just randomly decides when it is going to work.
This is with the canopy antenna sticking out of the fan cover, the switch hanging out of the box, and about 8 feet in-between them.
Then, on the other side of my house I have a second fan that always works fine, and it is farther apart and fully installed in the wall.
When they are working they are perfect for what I need, I just wish I could get it to stay stable. At least the z-wave connection to the switch is good, I can sit there all day and turn the switch on and off and it works every time. If only the canopy would follow the switch every time too…
