Thirdreality Night Light (Nightlight) - Unable to Pair Zigbee2Mqtt

I’m unable to pair the Thirdreality zigbee night light with my zigbee network.

I have two of the night lights, both show the same behaviour:

When I press the reset button and release it after the light turns red, the light cycles through green, yellow, blue in rapid succession. During this time, “permit join” is active in Zigbee2MQTT (counter is counting down), yet the night light isn’t being discovered.

It’s been some time since I added a zigbee device to this environment but prior, the only issues I had experienced is with figuring out how to get the device into pairing mode.

I figure this is another user error where I’m just not spotting the obvious and my head is hurting from repeating the same steps over and over. lol

My technology stack is as follows:
AMD CPU
Proxmox v8.4.1
Ubuntu Server 22.04.5 LTS
Docker

  • Home Assistant 2025.4.3
  • Zigbee2MQTT 2.3.0

Sonoff ZBDongle-P

Zigbee Stats:

  • Total 23
  • By device type
    Router: 18
    End devices: 5

Please help. :slight_smile:

I’m at my wits end trying to get these night lights to work. I purchased a total of three as I wanted to deploy them throughout my house to get a visual indicator when there are conditions (e.g. garage door open past “x” duration/time of day) that HA can identify and I should pay attention to. As mentioned, I tested this with two of these night lights and ran into the same issue.

Without help, I see no other option than to throw these out and find a different solution and, money spent aside, I don’t see good alternative options options. I haven’t found any other devices that would fit the bill as nicely (price, functionality) for my use case - if only I could get these to work. lol

This topic is not getting any traction. In the absence of specific suggestions on how to solve this problem, could you please suggest things I could do to get traction on it?

I’m thinking along the lines of

  • specific information I could add to help someone who looks at this post
  • a different forum I could/should post this in (perhaps this isn’t the right place for this)
  • etc.

Thank you in advance for your help.

Can’t help with specifics, but how far away from the coordinator are they when you’re pairing them?

Permit join has an arrow right next to it. Try selecting the closest router to your nightlight from that list.

Thank you for this suggestion.

I never dropped that arrow down (learned something new - thank you). There’s a floor in-between the nightlight and the coordinator, there’s a router about a meter from the nightlight and it shows an LQI of 99 in Z2MQTT, which I presume is strong enough for pairing.

In the past I paired devices two floors up from the coordinator without making a specific selection, but I’ll certainly try selecting the closest router and report back.

Your setup is not unconventional and should work. (It’s a supported device Third Reality 3RSNL02043Z control via MQTT | Zigbee2MQTT)

The instructions can be found at: https://3reality.com/wp-content/uploads/2024/09/Multi-Function-Night-Light_UM_20240920.82.pdf

Make sure you’re not on the local routine
Short press the reset button through the pinhole to enable or disable the local routine function. Pressing the button once and seeing a green light indicates that the feature is currently enabled. Pressing the button again and seeing a red light indicates that the routine is disabled.

This is how you got into pairing mode?
" Plug the night light into a power outlet using a USB-A power adaptor, it initially lights up green and turns yellow, indicating it is in pairing mode"

Thank you very much. I got into pairing mode by long pressing the button, then releasing when the red light came on, after which it resets and goes back into pairing mode. Turns out that this wasn’t the issue.

@ShadowFist, forcing to the closest router in Z2MQTT was the solution.

Once I did that, pairing was a piece of cake. No additional fiddling required, just put the Thirdreality night light into pairing mode and it connects almost instantaneously.

Thank you so much for this suggestion. I am still surprised that I was able to pair so many devices with the default setting without problems but happy I now learned of this additional feature from you and have a simple path forward for activating these night lights.

Next I’ll need to look at grouping them and doing the automation for using them as a visual indicator for conditions in my environment that require attention.
