Unable to add unsupported device

[JRaeuber]

Hello!

First of all, I am quite new to home assistant and I never had anything to do with javascprit, even if I do unterstand some basic programming.

I'm stuck at adding a new unsupported device.
It's an IKEA Silverglans LED controller.
Due to the compatibility to all the other IKEA devices I strongly assume that it works just the same way as the other two supported IKEA LED controller.
So my first attemp would be to just copy the configuration of one of the other IKEA LED controller from devices.js and change the needed parameters (name, model,..).

I have tried to add a new file (mydevices.js) to the zigbee2mqtt folder and add the filename below external_converters: in the configuration.yaml like written in the documentation.
I also tried to copy&paste the beginning section of the devices.js with all the const definitions and so on.

All I get is a lot of errors in the log file starting with

internal/modules/cjs/loader.js:883
  throw err;
  ^
Error: Cannot find module './lib/ota'
Require stack:
- /app/lib/util/utils.js
- /app/lib/util/settings.js
- /app/index.js

Seems like I am doing something horrible wrong.

Could someone please tell me what I need to do to get my new light to work?

Thank you so much in advance!

Best regards
Jonas

• Can you provide the log after pairing the device? Especially the line Device '0x00158d0001dc126a' with Zigbee model 'XXXXX' and manufacturer name 'some_name' is NOT supported, please follow https://www.zigbee2mqtt.io/how_tos/how_to_support_new_devices.html
• What features does this led controller support, only dimming or also color temperature?

Added, Changes will be available in the latest dev branch in a few hours (https://www.zigbee2mqtt.io/how_tos/how-to-switch-to-dev-branch.html)

Thank you again!

But could you explain in a few words how I can add a device like this to my own device list?
Maybe not everyday when I get an unsupportet device someone add it for me.
Would be interesting to know how it works!

Best regards

Can you post the content of your mydevices.js ?

[JRaeuber]

Right now it is empty, this LED driver would have been the first unsupported device for me.
I can't just add the part that you added above in the dev branch in my own device file, seems like there is missing some stuff around it - but which?

The syntax might differ a bit, you can find an example here: https://github.com/Koenkk/zigbee2mqtt.io/blob/master/docs/externalConvertersExample/light.js
