Error on level control for Busch-Jaeger 6715 (RM01)

[dreamsinmotion]

I updated to the version 1.15.0 and the level control for my Busch Jaeger 6715 (RM01) is not working any more. I have returned to the previous version 1.13.0 and everything works fine again. In version 1.15.0 I get following error log:

make sure you have no changes to devices.js (for hassio zigbee_sheperd_devices: true)

[dreamsinmotion]

I'm running zigbee2mqtt in docker and using the default devices.js

[Koenkk]

Are you sure there is no Docker volume mapped overriding zigbee-herdsman-converters? It looks that your zigbee-herdsman-converters is not compatible with your Zigbee2MQTT verison.

[dreamsinmotion]

Yes, I'm only mapping /app/data to a folder. My other devices are working as expected and the set state on the Busch Jaeger 6715 (RM01) is working as well. Only the level control doesn't work.

[Koenkk]

I've tried to (virtually, since I don't have the device myself) reproduce this issue but failed to do so.

@prutseltje @WinSCaP @docbobo is this working for you in Zigbee2MQTT 1.15.0?

[prutseltje]

I have the Busch-Jaeger 6711 U, this is only a relay. So I'm unable to test the dimmer function.

I am running Zigbee2MQTT 1.15.0 and do not experience any issues.

[docbobo]

Don't have a dimmer either... But 1.15.0 has been running without issues so far for me...

[Olli-Lolli]

I have the same issue with the level control of the Busch Jaeger 6715 dimmer.
I also looked into the code and the problem seems to be that the converter RM01_light_brightness in toZigbee.js uses the converter light_brightness, but this converter has been removed in a recent commit

    RM01_light_brightness: {
        key: ['brightness', 'brightness_percent'],
        convertSet: async (entity, key, value, meta) => {
            if (utils.hasEndpoints(meta.device, [0x12])) {
                const endpoint = meta.device.getEndpoint(0x12);
                return await converters.light_brightness.convertSet(endpoint, key, value, meta);
            } else {
                throw new Error('LevelControl not supported on this RM01 device.');
            }
        },

Tanks to @Tom-Black this got fixed. Changes will be available in the latest dev branch tomorrow (https://www.zigbee2mqtt.io/how_tos/how-to-switch-to-dev-branch.html)
