L8 Moodlight

[mssaleh]

First of all, Thanks for the massive, impressive effort. I have been trying to make use of these high-potential devices for more than a year. I managed to create several working prototypes using vanilla LVGL but no 2-way integration with HomeAssistant, and also with ESPhome (works nicely with HA but no touch!). I am beyond grateful for your generous contribution here.

Regarding the L8. Now with version 0.3.3, when I set up the backlight of L8 using moodlight (GPIOs r:26,g:32,b:33). The resulting entity in HomeAssistant (via MQTT auto-discovery) isn't working. I tried to create a manual MQTT light using the MQTT Light Template Schema in HA which worked only for on/off but not for color.
I created 3 sliders on a page and used groupid to link them to each GPIO directly from the HASP without HomeAssistant. This seems to work fine. Kindly take a look if have an L8.

Also, in general, I think it is possible to link a color-picker object with moodlight using groupid so we can directly control it without MQTT. It needs a bit of work but will make more sense than using HA or MQTT to change the backlight color on L8.

Best Regards!

I tried to read the code parts related to moodlight and groupid in order to help and contribute to this enhancement, but because I don't have enough C++ knowledge and there is very little comments in the code, I haven't got the confidence to submit a pull request.

My simple idea with minimal code change is to assign a pre-fixed groupid to moodlight (such as 888) and then modify to value normalization function to allow for the color hex code (with a simple "if" statement to create exception for groupid 888).

Hi @mssaleh,

Thanks for the input, I'm looking into this... The moodlight uses 3 groupids, one per PWM channel.
The way groups are currently setup, each object belongs to a single groupid. A colorpicker is special in that regard...

I think for HA to recognize the RGB values, the message needs to be in {"rgb":[255,255,255]}format.
I'm a HA n00b so I need to test that part some more, but this is certainly a goal to have that working too.

OK, I got the moodlight auto-discovery working in HA now.

[mssaleh]

Thanks a lot! You are really a github treasure! I have been extremely busy at work but I am planning to contribute to your effort in March.

Looking good, still need to add brightness support.

How do you guys use this with autodiscovery in HA?
I configure everything manually - can this be done too?

Any manual HA config sample perhaps?

[fvanroie]

autodiscovery is not yet working in 0.3.4, but in 0.4.0-dev it should work now

[nagyrobi]

But is there a way to use this with manual confuguration, not autodiscovery?

[fvanroie]

There is a moodlight command in 0.3.4

[nagyrobi]

Ok my problem was that my Home Assistant's MQTT was initially configured back when autodiscovery didn't even exist. Somehow autodiscovery refused to work but re-installing the MQTT integration solved this.

[nagyrobi]

But is there a way to use this with manual confuguration, not autodiscovery?

The custom component adds it manually so no more autodiscovery needed, cool.

[fvanroie]

autodiscovery was the only possibility for a while, this has been dropped now since we have a custom component that can handle it better.

[nagyrobi]

yes, that's why I thought I should mention this.

[fvanroie]

I think we can close this issue in favor of the openHASP custom component?

Looking good, still need to add brightness support.

Is brightness of moodlight implemented at firmware level? Or is it just missing from the component?
