Xiaomi Zigbee devices to MQTT bridge

I got Xiaomi zigbee switches working with zigbee-shepherd and hacked together a simple bridge to MQTT

Xiaomi Zigbee switches working with zigbee-shepherd

TL;DR Zigbee-shepherd now supports Xiaomi zigbee devices. Here is my zigbee to …MQTT bridge based on zigbee-shepherd: https://github.com/AndrewLinden/xiaomi-zb2mqtt Here is how I got Xiaomi Zigbee switches (WXKG01LM and WXKG02LM) working with zigbee-shepherd: 1. Flash your CC2531 with CC2531ZNP-Pro-Secure_LinkKeyJoin.hex from here: https://github.com/mtornblad/zstack-1.2.2a.44539/tree/master/CC2531 2. Xiaomi devices send predetermined attribute reports to coordinator endpoint 1 with profile id 0x0104 (Zigbee Home Automation profile). Zigbee-shepherd at the moment registers the 0x0104 profile to endpoint 2. So to get Xiaomi attribute reports working we need to swap the profile id-s of endpoints 1 and 2 in zigbee-shepherd. That can be done in lib/initializers/init_controller.js on line 64: ``` dlgInfos = [ { profId: 0x0104, epId: 1 }, { profId: 0x0101, epId: 2 }, { profId: 0x0105, epId: 3 }, { profId: 0x0107, epId: 4 }, { profId: 0x0108, epId: 5 }, { profId: 0x0109, epId: 6 } ]; ``` 3. Pair your switches. The WXKG01LM can be paired when after reseting the switch you keep toggling the reset for some time to prevent the switch to go to sleep mode before pairing process for zigbee-shepherd is complete. When you don't succees at first, simply try again. You can also try this fork https://github.com/HollyAssistTeam/zigbee-shepherd which has some patches to make pairing more forgiving if the new device does not answer. One must note that when pairing fails it is usually because shepherd fails to interrogate the device about its properties because the switch or sensor goes to sleep. But on the CC2531 ZNP pairing is done instantly when you reset your device https://github.com/zigbeer/zigbee-shepherd/issues/19 Such is the case with WXKG02LM too. This switch has no separate reset button and I could not keep it awake so shepherd would think pairing succeeded. But as the pairing on ZNP succeeds you can simply gather the neccessary info ieeeAddr and nwkAddr from the debug log and carefully craft a entry in lib/database/dev.db yourself. Then shepherd thinks it is paired and happily fires events based on the attribute reports sent by the switch.

@AndrewL Did you flash another firmware on the dongle or using the same one used for the binding?

I used CC2531ZNP-Pro-Secure_LinkKeyJoin.hex from here: zstack-1.2.2a.44539/CC2531 at master · mtornblad/zstack-1.2.2a.44539 · GitHub

Hi,
Is this the same firmware you need for the Zigbee binding?
Can you use the dongle with this and with the Zigbee binding at the same time?
Regards.

Firmware is the same I think. You can’t use one stick with this and the binding at the same time, you would need two sticks.
