Livolo light switch with Zigbee EC

Hardware
1

Hi,

I recently bought a couple of Livolo light switches that have Zigbee EC ( they are supposed to be a newer generation , I don’t know if that matters. Ex. model VL-FC3Z2-3G) . I tried to do an integration with Home assistant via Zigbee2MQTT and Mosquito Broker, but I’m not managing to even get them seen by Z2M when trying to pair ( I press for at least 5 seconds on the switch until it beeps and starts blinking rapidly )
I want to mention that I am using the ZBT-2 accessory, which maybe is the cause of not being able to pair the switches, since it’s quite new.

I did the changes to Z2M specific to Livolo switches :
advanced:
log_level: debug
channel: 26
pan_id: 6756
ext_pan_id:
- 33
- 117
- 141
- 25
- 0
- 75
- 18
- 0

The logs show just this, the Z2M is waiting for something to show up, but nothing shows up at all :

[11/30/2025, 1:33:49 PM] frontend:api:bridge: Sending {"topic":"bridge/request/permit_join","payload":{"time":254,"device":null,"transaction":"mvsny-1"}}

[11/30/2025, 1:33:49 PM] z2m: Zigbee: allowing new devices to join.

[11/30/2025, 1:33:49 PM] zh:ember: [STACK STATUS] Network opened.

[11/30/2025, 1:33:50 PM] z2m:mqtt: MQTT publish: topic 'zigbee2mqtt/bridge/response/permit_join', payload '{"data":{"time":254},"status":"ok","transaction":"mvsny-1"}'

I was expecting to at least detect the device and fail, but it’s not even detecting it. Am I doing something wrong ?

Have you confirmed they are supported? I see that the listed Livolo devices on zigbee2mqtt.io have a lot of special limitiations:

These devices can only be used on channel 26.

Therefore these devices may not co-existence with other Zigbee devices. Maybe, you need to add a dedicated coordinator and create a new network for Livolo.

To allow the device to complete its interview, re-pairing needs to be initiated on the device before the device exits pairing mode (ie before the rapid flashing sequence finishes and as soon as the device appears for the first time in Zigbee2MQTT)

I think it should be supported, it should be under one of these 2 categories :

And yes, I followed the instructions, as I mentioned in my initial post I put these settings in Z2M :
advanced:
log_level: debug
channel: 26
pan_id: 6756
ext_pan_id:

  • 33
  • 117
  • 141
  • 25
  • 0
  • 75
  • 18
  • 0

Also, these are the only Zigbee devices I’m trying to integrate in Home assistant. I just bought the addapter ZBT-2 and these switches are the first ones I was planning to add in my HA ecosystem.
