LZW36 and Unifi Users

[Hoveeman]

Hi Everyone! There is a discussion thread for Canopy Disconnect issues, and there appear to be a lot of users that have Unifi APs. LZW36 Fan/Light Switch Canopy Module Disconnection Issues

It’s been stated that the manufacturer has validated there shouldn’t be any RF interference issues, however I thought it might be useful to enter our Unifi Setup info in this thread to see if there are any similarities in our setups.

• Are you having Canopy Disconnect Issues?
• Number of LZW36 Switches
• Model of AP and quantity
• Firmware Version (New firmware came out today 7/7/20)
• 2.4 GHz Channels being used
• HT20 or HT40 Channel Width
• Total count of 2.4 GHz Clients
• Any unique SSID configurations like BSS/Beacon/DTIM/etc
• Pic of RF Scan

EDIT: Added number of LZW36 Switches and Canopy Disconnect Issues

My house has Ubiquiti gear throughout: 8 Access Points: 3 UAC Lites, 2 Outdoor Mesh and 3 In-wall. Running 4.19 (not sure the exact number, but it’s not the one from today). I have the AI installed to distribute the channels around, but had initially set everything up with HT40 (on 2.4GHz side). Don’t ahve any unique SSID configs, though I am running RADIUS and putting devices into vLANs. I’ll have to get a pic of the latest RF Scan, but did run it and didn’t notice anything abnormal.

That said, I do NOT have any issues with the LZW36 (so far).

Further more i disabled the 2.4 GHz frequency on the AP closest to the switches and the disconnection have dropped off significantly, but not gone…

The disconnect issues appear to be resolved with a new firmware update. I have applied the firmware and have been running reliably for multiple days. I will mark this as solved.

LZW36 Fan/Light Switch Canopy Module Disconnection Issues

UPDATE: We may have found an issue and there is a beta firmware that is addressing this. Good news is it’s with the switch, so it is OTA (with the right tools). In a nutshell: Sometimes when the commands are being sent from the switch to the module via 2.4 GHz, and the module also sends data to the switch, there is a logic confusion which makes a separate command from the switch not send to the module. We are internally testing this for two more days to make sure the release is stable and we’r…
