How do I get lux / light sensor information från Xiaomi Aqara?

Yes, I flashed it right after opening the box, based on this guideline; it walks you through all the steps, including which firmware to use:

*Important note, since you are just starting your Zigbee coordinator network, please make sure to design your network securely to make sure you arer not using the default usecure keys which are widely known. Unfortunately this is highly neglected to be mentioned in any of the guidelines.

  • Shutdown zigbee2mqtt addon

  • Open <homeassistant_ip>\config\zigbee2mqtt\configuration.yaml

  • set network_key and ext_pan_id like so (but use your own numbers between 1-221):

    advanced:
    network_key:

    • 1
    • 2
    • 3
    • 4
    • 5
    • 6
    • 7
    • 8
    • 9
    • 10
    • 11
    • 12
    • 13
    • 14
    • 15
    • 220
      ext_pan_id:
    • 1
    • 2
    • 3
    • 4
    • 5
    • 6
    • 7
    • 221

Change the below aswell from defaults:
pan_id: random 4 numbers, like 7658
channel: 15

  • Remove coordinator_backup.json
  • Restart and repair all your devices

Awesome, glad to hear that it worked. I hadn’t come across the Dongle-E video, just the Dongle-P, which is the one that I opted for. After purchasing it, found that it didn’t require flashing, whereas the Dongle-E did require flashing (returned since I couldn’t find out how).

I asume this is still the same and has not changed ?
