How to make LUT file without Hue bridge

[cascer1]

If no automated solution is available, perhaps it could be possible to make fuzzy LUT files? For example, I would manually cycle through some brightness and color settings and put those in a LUT file in the correct format, and then the integration would interpolate missing values.

For example, I would manually cycle through some brightness and color settings and put those in a LUT file in the correct format, and then the integration would interpolate missing values.

It is really possible only with brightness only bulbs - every each brihghtness % (100 manual measurements takes about 0.5-1 hour).

But of course you could try (automated measurements in hs-mode, which produces in reality "fuzzy" LUT file, takes about 20h-30h), so maybe it is possible for really patient person.

Is there some way to make it work using conbee too?

As I know it is possible, but you must define LUT mode manualy - you can use of course existent LUT files (if they fit your bulbs).

example - Philips/Signify LCT010 defined "by hand"

sensor:
  - platform: powercalc
    entity_id: light.my_lct010_bulb
    manufacturer: signify
    model: LCT010

Hi @nepozs

Thanks for your reply. What I meant with using conbee is if it's possible to generate a LUT file using conbee instead of the hue bridge.

If you are able to modify measurement script it will be possible, but I can not help with this…

BTW I have some models planned to measure, but I'm short of time.

I'll see if I can make a script to measure the values using HA commands instead of talking to a hue bridge, perhaps that way it can work with more lamps too (by targeting a light and sensor entity through the HTTP API perhaps). I ordered a Shelly plug a few days ago and expect it should arrive any moment now so I can start measuring some things too.

Most of my lamps (which aren't already in the LUT files) are installed without a plug, but I do plan on getting a Shelly 1 PM to measure those in the future. These are the following models:

• Philips 4090330P9_01
• Philips 4090330P9_02
• Philips 3216231P6
• Signify Netherlands B.V. LTG002

@cascer1 Great you want to contribute by measuring some lights.
Yes you are right, the current script only works with the bridge. I've build the measure script with the Hue API so I had the lowest latency, but I think using the Home assistant API would work just fine. I don't have a Conbee stick so cannot help with that. You could have a look into the current measure.py script and modify to your needs or create one from scratch.
Maybe I will add a measure script in the future which uses HA directly, but have some improvements for the component which I want to do first.
