Zigbee2MQTT version

Current version: 2.5.1-1

Comments

This is a SMLIGHT SLZB-MR3. I'm not sure how the support needs to be structured for this because it has two radios. There is a EFR32MG24 which is working fine as both a co-ordinator and a router. The issue is with the CC2674P10. I have flashed it to the current release version of the router firmware but there is no support for it. This is the same chipset as Koenkk/zigbee-herdsman-converters#9637 but it's in a POE dual radio device.

I have tried both the latest dev firmware and release firmware for the TI Chipset CC2674P10 and neither seems to be supported as a router

External definition

export default {
    zigbeeModel: ['SLZB-MR3 CC2674P10'],
    model: 'SLZB-MR3 CC2674P10',
    vendor: 'SMLIGHT',
    description: 'Automatically generated definition',
    extend: [],
    meta: {},
};

What does/doesn't work with the external definition?

Nothing. I'm assuming it needs to look more like the definition of the router profile for the EFR32MG24:

import * as m from 'zigbee-herdsman-converters/lib/modernExtend';

export default {
zigbeeModel: ['SLZB-06Mg24'],
model: 'SLZB-06Mg24',
vendor: 'SMLIGHT',
description: 'Automatically generated definition',
extend: [m.onOff({"powerOnBehavior":false})],
meta: {},
};

Or the O7P10 that was just added:

Added!

Changes will be available in the dev branch in a few hours from now and in the next release which is every 1st of the month.

Could you also submit a picture for the docs? This can be done by:

1. Create a fork by clicking here
2. Go to the public/images/devices directory, Add file -> Upload files
3. Upload the files and press Commit changes
4. Press Contribute -> Open pull request -> update title/description -> Create pull request

Make sure that:

• The filename is SLZB-MR3.png
• The size is 512x512
• The background is transparent (use e.g. Adobe remove background)

Awesome! I have asked SMLight to help us out with the image. If they don't come back to me soon I will just do it myself.

Please note that you cannot distinguish MR3 in router mode by the model/manufacturer of the Zigbee device.
The device uses firmware from SLZB-06p10 for Radio 2
