Hi,

and how set for a ikea color bulg (004.086.12) ?

:-)

Thanks for your time and share!

Best regards

Fernando.

Thanks for the script Wouter. I’m trying to turn on two lights with the script when there is motion detect but only one turns on. Any idea what could be causing this. This is how i defined the action of my automation:

action:

• service: script.turn_on_ikea_light data: brightness_pct: 50 color_temp: 365 entity: light.color_temperature_light_5
• service: script.turn_on_ikea_light data: brightness_pct: 50 color_temp: 365 entity: light.color_temperature_light_6

I know this is old but FWIW I managed to solve this issue by updating the Scene config (via the Deconz API) every 5 mins. This works because the ‘Zigbee Scene’ is stored inside the globes.

The following adjusts the white balance into sunset with a special late night mode to help preserve your night vision:

from requests import post, get, put
from datetime import datetime, timedelta
import json

deconzkey = '<use your own>'
hassauth  = {
    "Authorization": "Bearer <use your own>",
    "content-type": "application/json",
}
sceneid   = '2'
mins_transition = 60
noon_xyb = [0.324, 0.329, 254]
dusk_xyb = [0.501, 0.39 , 254]
late_xyb = [0.461, 0.306, 35 ]

response = get('http://deconz/api/{}/groups/5/scenes/{}'.format(deconzkey,sceneid))
scene    = json.loads(response.text)

response = get('http://homeassistant:8123/api/states',headers=hassauth)
states   = json.loads(response.text)
sun      = [x for x in states if x['entity_id'] == 'sun.sun'][0]
tzoffset = datetime.now() - datetime.utcnow()
now      = datetime.now()
sunset   = datetime.fromisoformat(sun['attributes']['next_dusk']) + tzoffset
sunset   = sunset.replace(day=now.day,month=now.month,year=now.year,tzinfo=None)

blend = min(max((sunset - now).total_seconds() / 60,0),mins_transition) / mins_transition
if now.hour <= 5:
    xyb = late_xyb
else:
    xyb = [noon_xyb[i]*blend + dusk_xyb[i]*(1-blend) for i in range(3)]
    
for light in scene['lights']:
    url = 'http://deconz/api/{}/groups/5/scenes/{}/lights/{}/state'.format(deconzkey,sceneid,light['id'])
    response = put(url, data=json.dumps({"xy":[xyb[0],xyb[1]],"bri":xyb[2]}))

This could be adapted to accept color and brightness - create a quick scene and immediately switch to it.

Hello everyone,

i am new to home assistant. I would like to know if it is possible to change the color temp stepless?

Hi Wouter,

Thank you for your script!

However I couldn’t get it to set temperature of my IKEA trådfri groups (i.e. “rooms"in the trådfri app). It will just adjust brightness in sync, but never color.

entity: light.living_room #group/room created in trådfri app - only contains bulbs that can do color-temp and brightness color_temp: 333 # swap between 333 and 454 - nothing happens brightness_pct: 100 #swap between 1 and 100 - always updates in sync

Do you have a suggestion of what to look at?

Hi Wouter, Wanneer ik dit invul in de automation, en hem wil saven krijg ik op color_temp een fout melding.

type: turn_on device_id: f5c3559faa9eecfe4c975bcf70fbf914 entity_id: light.0xbc33acfffea07865 domain: light brightness_pct: 80 color_temp: 350 Enig idee waar dat ik zou kunnen zitten

Hey there,

“white”: does nothing, does anyone know how to trun off the white in NR to use only colour?

I can see that using the colour temp brings back white. But cant turn white off?
