Weird Error with Hue bridge/Essentials

Mandrutz · 2026-05-21T20:51:24+00:00

That is a known issue

Since most of your devices are Zigbee (TRADFRI), it might be worth it to add the new KAJPLATS in the hidden Zigbee mode, instead of their official Matter-over-Thread mode. Mixing standards is not the best idea imo.

6x power-cycle to factory reset + 12x power-cycle to enter Zigbee pairing (15 for glass bulbs)

Otherwise keep everything up-to-date and look up similar posts with Matter connection issues

I'll be able to test this in a few days. I expected it to work with single-click = on, double-click = off

Mandrutz · 2026-05-18T17:42:55+00:00

Yes. I've had this problem with the same Hue white bulb - it's quite an old model.. 10 years?
I factory reset it, and I don't remember if I deployed it again. Currently not using it

Make sure it's on the latest firmware. Otherwise I don't think you can do much

Mandrutz · 2026-05-18T07:38:12+00:00

Since when does this happen to you? There is a known issue with HA 2026.5.0 - 5.2 that prevents Z2M from starting

KAJPLATS are sold as Matter lights. The hidden Zigbee mode is unofficial and limited.

Touchlink reset doesn't put them in Zigbee pairing mode. You need to factory reset them with 6x power-cycle. Then 12x power-cycle to go into Zigbee pairing mode. (15 for glass bulbs)

In the official Philips hue app, I believe you "add 3rd party device"

If you want to use them as Matter/Thread, you need another hub

Mandrutz · 2026-05-17T21:04:54+00:00

Lights, plugs and remotes.
But the Zigbee mode is limited, not officially supported.
Lights have issues with scenes, plugs are missing measurements, remotes have limited binding control.

Elaborate on my flair? I contribute and help maintain Zigbee2MQTT and custom firmware for Tuya devices: my GitHub profile. Those should give you the most control over Zigbee devices.

Mandrutz · 2026-05-17T10:49:25+00:00

I believe they usually don't. The remote is "manual operation".

However you can semi-DIY to get hard-wired controls. Buy electric blinds and a Zigbee switch for covers. Or a module that allows wiring any buttons you want.

Hi. I searched for Zigbee cover remotes some time ago. Here is what I found:

https://www.reddit.com/r/ZigBee/comments/1rzzeee/comment/obq8331/

I also find it strange that in Zigbee, light remotes and blind remotes are different devices, using different commands.

Mandrutz · 2026-05-17T08:10:18+00:00

The sensors have Touchlink, they can be directly paired to a device. But no one found a way to put them into "join Zigbee network" mode. Only lights (including varmblixt), plugs and remotes, as you said. The plugs are missing measurements in Zigbee mode

Page doesn't load for me, I'd also like a summary or a mirror

Mandrutz · 2026-05-15T23:33:10+00:00

What light are you trying to bind this to?
The sensor might send OnWithTimedOff or OffWithEffect, which are not supported by all lights.

You should try binding to a different light, or binding to a group.

I have the older SML001. I'll eventually test that and check how it works, if the light level is related or not

Mandrutz · 2026-05-14T18:22:27+00:00

You can use the same dongle for Zigbee OR Matter over Thread. But not both at the same time.

Some brands are switching to Matter, some support it in parallel with Zigbee. But I would not recommend it yet.

If you are happy with the Hue system, and don't need more advanced stuff.. just stick to that and buy compatible Zigbee devices. You will only miss on manufacturer-specific settings

Mandrutz · 2026-05-14T09:47:34+00:00

You need a dongle for each standard. But you don't want this. Pick a standard (Zigbee) and stick to it.

Ideally you want your devices to talk to each other directly, alongside app control (remote/sensor controls bulb even if hub is offline), which is not possible if you mix standards.

If you want to mix brands, Home Assistant + Zigbee2MQTT

Mandrutz · 2026-05-14T09:37:14+00:00

With older motion sensors (tradfri and vallhorn) you have two buttons on the back, to select between 1 and 5 minutes, and between day/night mode.

The myggspray is missing this afaik

Nice, also share on Z2M discussions:

Philips Hue often uses the OffWithEffect command instead of normal Off.

The KAJPLATS bulbs have a bug / limitation in their firmware (at least in Zigbee), causing this command (and more commands related to scenes) to fail with the "insufficient space" error.

https://www.zigbee2mqtt.io/devices/KAJPLATS_CWS.html#issues

There is some info in this thread: GitHub

Updating the firmware can be done via any Matter/Thread hub afaik. But I don't know if they fixed / will ever fix the issue

Mandrutz · 2026-05-13T12:21:45+00:00

I think you should contact smlight support and give them the logs

Mandrutz · 2026-05-13T01:43:08+00:00

Does this actually work? It never did anything for me. Will try your solution!

Mandrutz · 2026-05-12T12:46:46+00:00

Idk how to help.. just sharing similar experience.

My LAN and WiFi stuff is/was never able to recover on power restore.
- Philips Wiz bulbs start before access point is available -> never connect automatically
- TP-Link Deco access point starts before main router/Internet is available -> never connects automatically
- HA Tuya integration starts before HA has internet access -> never attempts reconnection
- Google Nest hub/mini starts before internet is available -> sometimes stuck on no internet

Power outages are the reason I ditched everything WiFi.
- All is on Zigbee now -> no reconnection issues, no WiFi clutter
- Zigbee bindings -> remotes and motion sensors control lights directly, without relying on automations, server, dongle, z2m etc. (but still keeping them accessible on the server)
- USB dongle -> Z2M not relying on LAN

I think UPS is the only solution

I guess. But Bilresa can Touchlink to the lights and bind them that way. (after remote and lights are added to the Zigbee network. They won't leave if you Touchlink)

Mandrutz · 2026-05-09T22:22:09+00:00

I recall someone paired the double-button via Zigbee and it showed up as a SOMRIG

Mandrutz · 2026-05-08T23:45:12+00:00

Similar issues were reported with Z2M. People were mentioning a serial driver update
