yes it’s possible however on/off state is common for all channels. So in result you could set brightness and warmth independently, but turn on and off would work for both strips at the same time
hi, How your project works? I think about the same? Is it work?
I just did this and it seems to be working ok. I used a Shelly RGBW2 and tunable white led strip.

Is templating like this possible if shelly rgbw2 is configured as four white cannels?
If yes, can you show me how?
@lpt2007 Hi! Sorry it took me a while to get back to you. I’ve never used a Shelly RGBW2 with 4 white channels but I think it would be possible.
Here’s the HA documentation for the template light:
The on/off should be pretty straight forward against the two lights instead of one. You’ll need to build some logic for the temperature_template, level_template, set_level, and set_temperature.
For example, to get the temperature_template you might start with a formula like this:
cool_light_brightness / (warm_light_brightness + cool_light_brightness) to get a “% cool” value.
Then you could use “% cool” to determine mireds. (100% cool means 153 mireds, 0% cool means 370 mireds.) Assuming this is linear, the final equation for your temperature_template might look like this:
mireds = - 2.17 * (cool_light_brightness / (warm_light_brightness + cool_light_brightness)) + 370
You’d reverse the process to know how to assign the cool and warm light brightness given mired value.
Thx for reply.
I already find solution here:
Is still little buggy, but working:)
Hey! Thanks for this. May I know how did you do the calculations, so I know how to adjust it if I connected the cool one into blue (instead of green) and warm white into white (instead of red)?
Anyway, in the end, I flashed ESPHome OTA: Shelly 2.5: Flash ESPHome Over The Air! | Savjee.be with this config and it works perfectly:

Hey!
I just followed the same steps, however I’ve not been able to flash ESPhome after Tasmota.
It says the device has not enough space to do it OTA.
Any tip?
Did you try Tasmota-minimal?
Fixed it flashing old fashion way: wiring
I was in the same position as OP: Shelly rgbw2 + CW/WW LED strip only controllable as two separate lights.
The existing templates I found were either a bit buggy or didn’t allow to set the LED strip to full power (CW 100% + WW 100%), so I created a new template that solves the original problem in addition to unlocking the option to set the strip up to full power.
There is no need to reflash the controller or install any additional component. Here is my blog post with a detailed explanation, link to the template code and instructions.

Thanks for the github/blog post @gfra. I´m new to this type of configuration so I´m a bit confused where to put the yaml file you have created.
I have put it in the config folder and replaced the UPPERCASE entries - but the new light entity is not appearing anywhere after restarting HA. Should the «template_light_cwww.yaml» file be referenced in the configuration.yaml somehow?
Thanks 
Yes, you have two options:
- Copy and paste all the content of the yaml file in your
configuration.yaml, see the template light docs for an example of this - Add a reference to the template light yaml in your
configuration.yaml, I created atemplate_lights/directory where I put all my template light yaml files, below the code
configuration.yaml
light:
- platform: template
lights: !include_dir_merge_named template_lights/
Let me know if you get it work! 
@gfra. Hell yes. Thanks for writing up that template. I just installed a bunch of Carro ceiling fans w/ lights. The lights are setup as 2 separate entities in the Tuya integration tied to Home Assistant. I was able to use your template to mesh the warm and cold channels to create a single entity that can be controlled from Home Assistant. WAY better than messing with each channel by themselves.

I got the same fans and I’m struggling with the same issue, can you show me the template that worked for you?
Finally got the time to test this properly. Works perfectly when operating the light card manually - but when creating scenes only the color temperature seems to be saved.
I.e scene «Daytime» will have 100% brightness and 4000K. «Nightlight» scene is saved with 20% brightness and 2700K. When activating the scenes only the color temperature changes. The brightness remains on whatever setting it had before activating the scene.
Any idea what could be causing that?
Thanks for your help:)
Sorry, just seeing this message. This was a bit of a process, you’ll need to research setting up the local Tuya integration in HACS. I originally started with the Carro app, then had to unpair from that app and switch over to the Tuya app, giving me access via the Tuya developer portal. From there, I created a Tuya developer account and was able to get at the parameters of the fans. I then went back into HA and added the Tuya local integration and added my fans using the creds I found in the developer account. Hopefully that helps somewhat.
Hi
I am new here and I want to do the same.
I have two entities CW/WW.
- number.fl_licht_led_cw
- number.fl_licht_led_ww
Can you help me with the code? How I have to prepare him?
