Request is not stale, few more users (@to0b, @pimw1) are waiting for the support of the new device.

This device has raving reviews all over the internet; from a commercial point of view it would (imho) be wise to bring support for it with all bells&whistles attached.

[Mimiix]

If it was following the standard it should be working already out of the box.

@Smanar can you help with a DDF?

Yes, exactly, what is the problem with this device ? What is working or not ?

@TUNER88 , could you reply to the question of Smanar? :)

[ebaauw]

I would suspect the main lamp to work out of the box (as a Color Temperature Light); Color Capabilities on the first endpoint correctly indicates it only supports Color Temperature. The colour ring on the second endpoint should be exposed as an Enhanced Color Light. The only issue with both endpoints is the ZHA device type: Color Dimmable Light; if memory serves, we needed whitelisting in the legacy code to correct that. Creating a DDF for this would be pretty straightforward. My main concern is that neither endpoint seems to support PowerOn On/Off.

The real challenge will be the effects on the colour ring. I suspect they use the LUMI specific cluster for these. We would need some serious sniffing while the light is connected to the Aqara app to reverse engineer how to control these. Probably need some serious JavaScript hacking for that, as we needed for the Hue gradient lights.

What's the issue with the light? @Paule-Panter please see the question of Smanar

[Paule-Panter]

I can switch both endpoints on/off.
Both endpoint are exposed as "Color dimmable light", but the first (main) endpoint has physically only 2colors (cw and ww). At the moment i can't switch/fade between this colours.
The outer ring has physically individual adressable LEDs.
It exposed as one "Color dimmable light", therefore it is only controlled as one light, so far.

[ebaauw]

The device types are from ZHA. In ZLL / ZB3 terms, the first endpoint (main light) is a Color Temperature Light; the second (ring light) an Enhanced Color Light. Note that the second endpoint only contains RGB LEDs; colour temperature is emulated using these.

Both light endpoints seem to provide the same functions (apart, obviously, from the colour):

• On/Off Cluster: Basic On, Off, and Toggle commands. No Off with Effect, no On with Timed Off. No Startup On/Off attribute. Xiaomi have a manufacturer specific variant of this (0xFCC0/0x0517);
• Level Control cluster: basic commands, incl. Move to Level (with On/Off) work. Options, transition time attributes work. On Level just mirrors the current level and isn't settable. No Startup Current Level.
• Color Control cluster: first enpoint only ct (from 153 to 370), second endpoint ct (same range, but emulated using RGB LEDs) and xy. No hs, no colorloop. It doesn't report the gamut. Startup Color Temperature is non-functional.
• Groups cluster: reports 8 groups for each endpoint.
• Scenes cluster: still need to look into that, particularly if it supports ct.
• Lumi specific cluster: Poweron On/Off (0x0517) does work (RTFM: 0 is on, 1 is previous, 2 is off). Both endpoints report 10 segments (as per the attribute used for the LED strip). The Aqara app supports (non-colour) effects on the main light as well. These are using this cluster, but I need to look into the details.

[ebaauw]

Created an initial DDF, but the lights resource for the first endpoint somehow exposes state/xy. The corresponding attributes are also being polled. I suspect this is the legacy code dealing with Color Dimmable Light.

[Paule-Panter]

Thanks for this huge information and the ddf.
I'll try this after my holiday vacation.

I would like to read the 'RTFM' for the Lumi specific cluster with the crazy states, where can i find this?

Best set DDF Mode to Strict in the Control panel when testing the DDF. Otherwise the legacy code is kicking in, applying messages from one endpoint to the other resource, or ignoring them.
EDIT Should no longer be needed after adding the non-public xy to the resource for the first endpoint. Needs the legacy PR to suppress xy from being reported by the API, though.

I don't think there is a manual describing the LUMI specific cluster, at least not in a language I can read.

Most of our knowledge has been obtained through reverse engineering: changing stuff in the Aqara app while sniffing the Zigbee traffic between the Aqara hub and the device. This knowledge is documented in GitHub issue, and summarised in general.xml (use the Source, Luke).

Is this device fully supported under DeConz now?

I'm thinking of buying one, but its unclear if there are still outstanding issues to resolve here

[ebaauw]

No support yet for special scenes nor for gradients, see #7895.

I'd like to use/test the respective DDF, however my Lamp seems not to be seen by my RaspBee II deCONZ-gui at all. Does somebody have any experience or a link to a HowTo-page for connecting the T1M with RaspBee family of ZigBee adapters? (Perhaps I have also just a hardware issue with my lamp ...)
Thanks a lot!

I just figured out, that there was an issue with power supply caused by a defective wall switch which in turn caused some undervoltage or so. So lamp was just continously "breathing" (probably indicating a undocumented fault state).
After replacing the wall switch, the lamp behaved properly as described here and other forums using raspbee II, deCONZ and Home Assistant.
