Could help but I am not sure if a particular length is ‘tuned’ to a frequency. Antennas are weird that way where it isnt always just putting something bigger in, it also needs to be the right size.
Maybe I am thinking about this wrong, but I would guess the average distance from the switch to the canopy is in the 8-10’ range plus the signal needs to (in some cases) travel through a metal canopy case. Was that what you were thinking in terms of distances when you said a few feet?
Makes sense! I figured this angle had already been explored (or not given all the specifics about antennas). Just wanted to throw it out just in case 
It seemed to be distance/obstruction related for me too.
I have 1 LZW36 that wouldn’t pair at all at about 15 ft. from the canopy, but works nicely at 8 ft. Another one is about 12 ft. away, it was very unreliable until I pulled the antenna wire out beyond the canopy. Now it’s quite reasonable; works 95% of the time.
Is there an update about this? I have 2 switches and if one works the other doesn’t. It bounces back and forth.
I am wondering too? I am also have the issue where the lights will shut off on the switch and I have to turn the power off to the switch to get them to come back.
Any update on this? I did not even realize this was an issue.
Have 3 switch, 2 have been fine, 1 has had issues mostly since ive had it. Probably 2 years or so.
It seems like @Eric_Inovelli just doesn’t care about customers who bought this switch. He’s more concerned about bringing new partners online to push the 5-button switch…
I like the red series, but this kind of support and responce is why I’m no longer buying Inovelli switches… I REALLY hope things change, because I’d like to get 3 more fan/light switches and 4-5 5-button switches…
It’s not that I don’t care, I am just caught in a rock and a hard place. We have a manufacturer that doesn’t want to work with us and won’t help us solve this issue. We’ve said we would give refunds to whomever wants it and have replaced all that we can.
I’m not really sure what else to do at this point.
We are working on bringing these partners you’re referencing on to help us negotiate with this manufacturer. I’m hoping to have some resolution in the next month or so.
I wish I had better news, but I really don’t know what else to do outside of refunding anyone who has an issue which we’ve done already?
What do you propose @tidesraty?
I’m still using my fan/light switch, but it does cause issues, as it doesn’t seem to like to get or send two commands in quick succession, but if you give it a minute between commands, it is usually fine. The worst is that anything that relies on it for repeating also doesn’t work during that time. Plan to replace it with the Zigbee version, when that comes out.
I didn’t see this suggestion in the thread. Yesterday my fan + light switch seemed to lose connection to the fan. Button presses would not change the light or fan, though the LED strip would change. Same with Zwave commands sent from Home Assistant.
In sheer desperation to turn off the light on the fan, I pulled the chain on the fan. After cycling through the fan light and fan speed with both chains, the switch started responding again.
Hope this helps someone out there.
This worked for me as well, air gapped the switch, cycled through the fan and light setting on the fan itself then pushed in the air gap and it started to respond again.
I have three of the LZW36 switches deployed on a Hubitat C7 fw: 2.3.1.139, and only one works consistently. Two of them are deployed in a 2 gang box controlling two of the same model fans with chain pulls on either side of a living room. One switch (south fan) is <5’ away from the fan, and the other (north fan) is <15’ away. Only the one closest works consistently. I’ve flashed the firmware on the north fan to 1.36 hoping that might solve the issue but with no luck. Pulled the air gap on the non-working switch for 5 min and then it started working again until I tried to turn light on/off and set fan speed in somewhat rapid succession. Another interesting symptom is the lights in the (north) fan pulse/flash briefly every 5-10 min. Just a quick flash.
The 3rd switch is in the bedroom. Different fan model, but also a pull-chain control. The light works slightly more consistently than the fan.

@Eric_Inovelli : Hoping you will have some news before summer when we need the fans!
I kinda got this working 100%, but it involves Shelly, Homeassistant, node red and a third party wifi canopy module.
I bought this module, hooked it up at the fan canopy, integrated it with LocalTuya to homeassistant, Then I created rules in node red to set the switch led status to whatever the LocalTuya integration said (so if fan is at level 2, set led bar to 66% for fan button, etc). Then I created rules for the switch to control the fan through the wifi integration.
After this, I still had trouble with the canopy losing connection to wifi about once a day, so I put a Shelly 1 in the canopy to cut power whenever homeassistant detects that the fan is offline, waits 5 seconds and turns fan back on. It’s a bit convoluted but right now it works 100% of the time. I’ll update this post tomorrow with my node red nodes and the Shelly / homeassistant automation.

Here’s the automation built off of this HA Blueprint for using the Fan/Light Switch Combo as a remote for the WiFi Canopy Module I bought:

Its a super nice feeling to randomly see that blueprint being used elsewhere (I’m cree8). I need to go ahead and fix it so that it stops generating HA errors.
On topic, I did have some trouble with my LZW36 last year, but lately it has worked pretty consistently. The only thing I notice now is that the canopy module produces a loud buzzing when the 3 lzw42 bulbs are on at full brightness.
Its unfortunate that the manufacturer is not easy to negotiate with, but I’ll chime in like many others and state that the transparency provided here is 2nd to none, and really endears me further to the product line.
I hope that Inovelli eventually gets larger so that it has more power in these negotiations, but that the transparency never goes away.
Cheers!
…or able to hire an in-house firmware engineer and stop using (and being held hostage by) their vendors’ overseas programmers. It isn’t rocket science to develop firmware these days, and I’d bet that eliminating the language barrier and 24-hour time zone delay in getting responses would surely speed development…
Under the same name on HA forums, I think I threw a recommendation out there, but there’s been a weekend since :D.
Its been on my mental agenda for months actually, since the previous guy in that thread mentioned it. Typical procrastination behavior out of myself 
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.
Honestly that blueprint is awesome! Thanks for making it!
