LUT file support for only brightness mode

[bramstroker]

Support for lights having only brightness mode (no color temp or hs modes). For example LWA001 only supports brightness

[nepozs]

LWB010 also has brightness only.

[bramstroker]

@nepozs I have bought a Hue filament light which also have only brightness. This will be delivered next monday. Than I can check if this works with the component or I need to do any changes in the code.

Regarding LWB010. Are you able to measure this light and provide a LUT file? I don't have this light so I cannot do it.

[nepozs]

I can do it only manually, so it will take lots of time, but I'll try to prepare it. I have also LWB004 (very old version named Hue Lux).

[bramstroker]

@nepozs for only brightness mode I would advice to take measurements for steps of 5 brightness. Brightness is from 1 to 255. So take measurements for 1, 6, 11, 16 etc. This would be like 51 data points, which is doable manually. For the Hue/saturation mode we take 40.000 measurements. Imagine doing those manually 😂😂

[nepozs]

I've prepared them with 100 datapoints because the bulbs have nonlinear characteristic (it is maximum doable by hand :P with 1% brighness incerement using HA interface, so they are real use datapoints), I've created pull request with files (hope they will be useable).

BTW I'm using also many Ikea bulbs, some Ligtify/Osram, Jaiawen (Feibit) and innr, but without possibility to automate measurments I'm able to measure only dimmable models, but I don't know proper directory structure to do it. From Philips Hue family I have also LTW010 (White Ambiance E27) and LLC011 (Living Colours Bloom), but they need automated measurment.

[bramstroker]

Thanks for doing the measurements for LWB001 and LWB010, this will also help others.

To determine the correct directory structure fir the other manufacturers could you try the following?

• Enable debug logging (see last chapter in readme)
• Add the light to the powercalc sensor configuration.
• Restart home assistant

Now check the debug log, there should be some line "Auto discovered Hue model for entity". There you can see the manufacturer and model which are provided by the Hue bridge. Not sure if they are specific enough for the other lights yet. But we will find out.

About automatically measuring. There is a script included in the utils/measure folder, which I am using. I am using a Shelly S smartplug (it's a wifi plug), they are "only" like 20 Euro in dutch shop. When you get that one you need to modify the file measure.py for the smartplug IP address and than run the script python3 measure.py. Alternatively you can wait for others to do those light models (but maybe it never happens), or use the linear mode (to get a approximation).

[nepozs]

I'm not a programmer, but I understand spirit of open-source :D and I've seen this script before, so I have plans - Shelly Plug S sounds good,, in Poland it is slightly more expensive, but it is also available on Amazon.

It looks like brightness only LUT needs some code change

And one more thing - should directory be first word from full name of manufacturer? I can see e.g Signify Netherlands B.V. an directory is signify, so should next directories be osram and ikea?

Cool, you have to start somewhere ;-). Let me know if you have any problems with te script. I have added support for brightness to the measure script as well

Yes, I had the same error when testing with the Filament bulb that was just delivered at my place. Just made the necessary changes to the code to support brightness only mode. Will make a new release 0.1.4 in next 10 minutes. Also did the measurements for LWA004.

For the Signify manufacturer I made a mapping in code so the directory name does not need any uppercase characters and dots etc. See this line of code We can do the same for osram and ikea. However I am not sure yet about the models, need to think about that some more. I was hoping they had some unique model id like the Hue lights, to diffentiate them. Especially the Osram is identified as "Plug 1", not sure what that is about. Is it a light bulb or a smart plug?

[bramstroker]

Actually these model id's are zigbee id's. You can find them here: https://zigbee.blakadder.com/search.html

You can use exactly the same model id as listed in the logs as directory name. So keep the casing the same and spacing. So the structure will look like this

- data
  - ikea
    - TRADFRI bulb E27 opal 1000lm
      - color_temp.csv.gz

The Osram Plug 1 seems te be a smart plug. We cannot include this LUT file in the repository as everyone will have another appliance attached to the plug with other power consumption. Is this plug dimmable or only on/off? When it is not dimmable a LUT file would not make any sense, and you could just use the fixed mode.

[nepozs]

The Osram Plug 1 seems te be a smart plug. We cannot include this LUT file in the repository as everyone will have another appliance attached to the plug with other power consumption.

Osram Plug was first device I've tested, it is not dimmable (so LUT method of course is not proper), but I've made some observation - it itself uses 0.44W when off and 0.98W when on, so for future this integration could provide ready made database also for devices like that (it just could be simple definition, so user in configuration.yaml could provide only load wattage (without smart plug).

Let me know if you have any problems with te script. I have added support for brightness to the measure script as well

I don't have hardware like Shelly Plug (so I can measure "by hand" dimmable lights only, like TRADFRI bulb E27 opal 1000lm because I own Zhurui PR10 which is manual only), so I can't test script now.

For the Signify manufacturer I made a mapping in code so the directory name does not need any uppercase characters and dots etc.

If upper/lower case is so important I've prepared 2 lines in const.py

But as I know all Ikea Tradfri models (Zigbee hardware) look similar like this one - so any change rather is impossible (when I'll be able to provide LUT for more models ) so in case of models mapppings are rather excluded.

It's not supported yet to only supply standby usage in the model library/database, and I don't think I will support that because it needs a lot of code refactoring (changes in the code). You can simply define like this:

sensor:
  - platform: powercalc
    entity_id: light.outdoor_light
    mode: fixed
    watt: 0.98
    standby_usage: 0.44

The "TRADFRI bulb E27 opal 1000lm" seem to be a light where you can modify the color temperature. If this is the case you will need to measure different brightness levels and different mireds (color temperatures). This would be like 600-1000 data points, which is too much to do manual I assume.

I have read this sentence multiple times, but I don't really understand what you mean, sorry. Could you elaborate?

[nepozs]

The "TRADFRI bulb E27 opal 1000lm" seem to be a light where you can modify the color temperature.

I'm sure it is brightness only, Model with color temperature has added 2 letters inside - I will check it in a minutes. Edit: TRADFRI bulb E27 WS opal 1000lm has color temperature, but it is different model.

I've missed quote:

but in short - names of Ikea models must be very long.

[bramstroker]

You can just use the full zigbee ID as the folder name for the model. The zigbee id will be unique for every light. It does not matter that it is rather long, but it need to be exact.

Ok nice. Than you can do that one manual and get the light supported in the database
