Ikea Tradfri E14 470lm 2700 Kelvin Device Request

[amrap030]

Hello, could you please add the Ikea Tradfri E14 470lm 2700 Kelvin light bulb to the supported devices?

[sjorge]

Do you have a database.db entry for one + a link to the ikea page? I can probably figure out the devices.js entry for that based on that.

[amrap030]

I don't have that but on the packaging I can see Tradfri LED 470 lm 5.2W E14 LED1835C6 and under the barcode 704.243.12 19972.

[sjorge]

Looks to be this one then? https://www.ikea.com/nl/en/p/tradfri-led-bulb-e14-470-lumen-white-spectrum-wireless-dimmable-opal-white-chandelier-70424312/

[sjorge]

Just a complete stab in the dark, but yo ucan try adding this to devices.js

    {
        zigbeeModel: ['TRADFRI bulb E14 WS 470lm'],
        model: 'LED1835C6',
        vendor: 'IKEA',
        description: 'TRADFRI bulb E14 470 lumen, dimmable, opal white',
        extend: generic.light_onoff_brightness,
        ota: ota.tradfri,
    },

I can confirm that the linked IKEA-page is the product corresponding to the model number LED1835C6.

I don't understand where I am supposed to paste the suggested solution by @sjorge.

I have managed to pair the light - but after a zigbee2mqtt restart I receive

zigbee2mqtt:info 2020-03-29 22:20:40: Vardagsrum 2 (0x680ae2fffe713903): Not supported (Router)

The entry in the database.db-file

There is some info here https://www.zigbee2mqtt.io/how_tos/how_to_support_new_devices.html

Just use the entry from my previous post instead of the example and I think it should work.

The difference between the

• already supported LED1649C5 IKEA Germany Product Link ZigBee Alliance Certificate

and the

• not yet supported LED1835C6 IKEA Germany Product Link ZigBee Alliance Certificate

is that the new model (LED1835C6) offers a colour temperature control (3 steps from warm white to cold white) in addition to brightness control and on/off control which the old model (LED1649C5) already offered.

[mabachel]

Is someone out there who got it (LED1835C6) working?

[JBarrskog]

No, I have not. I run my home automation on a Raspberry Pi 4 using Docker and I’ve not been able to run “npm ci” in the bucket in order to get started. Have paused my efforts due to this struggle :/

[mabachel]

I just found this enrty in devices.js from the dev branch.

{
        zigbeeModel: ['TRADFRI bulb E14 WS 470lm'],
        model: 'LED1903C5/LED1835C6',
        vendor: 'IKEA',
        description: 'TRADFRI bulb E14 WS 470 lumen, dimmable, white spectrum, opal white',
        extend: generic.light_onoff_brightness_colortemp,
        ota: ota.tradfri,
},

LED1903C5 is listed under supported devices but LED1835C6 is not.

So there should be (some) support already in place..? Or not?

[Koenkk]

@mabachel if the zigbeeModel is already there, the bulb should work just fine. The model (just a cosmetic thing) will be updated automatically on the next zigbee2mqtt release.

[mabachel]

Thanks for the clarification. @JBarrskog & @amrap030 this commit is from May 25, 2020. Thus LED1835C6 should be officially supported in the next release. https://github.com/Koenkk/zigbee-herdsman-converters/commit/5b069f1892582c734ee31df005a8808afdc52f78

This issue can be closed.

@mabachel @amrap030 Can confirm that 1.14.2 works with LED1835C6. I had to fully remove the light before it would pair. Thanks alot!
