Yeelight led ceiling light compatible with HA


#141

Looks like moonlight mode is now supported in the library v0.4.0 as a “Power Mode” (5). So a boolean toggle for moonlight mode has be added to the light and multiple functions in the HASS side will need to be changed (bear with me, I’m new to this):

  1. Update: Check if power mode is 5 and set boolean.
  2. Turn_On: Add set_mode to set power mode.

The “transition presets” (HASS effects) in the library seem to be old and for RGB bulbs only. Since I don’t have an RGB yeelight, I can’t test those.

The new ones for the ceiling light, I can test once they are added to the library.


#142

I’ve added the moonlight mode to the Home Assistant Component recently. Check the docs!


#143

Yup saw that service LIGHT.YEELIGHT_SET_MODE now can set mode = moonlight. But it is not exposed in the UI.

EDIT: This is fine for me (and most) since I can use it in automations and scenes. The effects are probably better done first, IMHO.


#144

Guys, I’ve also tested the new yeelight.set_mode service and it works nicely.
This one: https://www.yeelight.com/en_US/product/luna

The only problem is when moonlight is activated, light.toggle on the wireless wall switch doesn’t work as intended anymore. I have to use HA or remote to take it back to normal.
Any workarounds or ideas?


#145

What do you do (at HA) to take the light back to normal? May be we can improve the behavior of the component.


#146

Well you have to change light.yeelight_set_mode back to normal, that’s the only way (call that service through separate automation for example), but then you get scorching white light, so it’s pretty useless for my scenario. It would be great it the mode could be turned to normal without turning the light on.

My scenario:

  1. on motion sensor turn moonlight mode on after midnight
  2. on motion sensor off turn moonlight mode off
  3. if someone presses the switch/button manually turn on normal mode (not last mode used which was moonlight).

Hope I’m making sense :slight_smile:


#147

I think you cannot do this with light.toggle. I use light.turn_on with kelvin and brightness_pct and the mode switches automatically back to sun mode, with colour and brighness as specified.
I use one click to turn the light on and double click to turn it off (some xiaomi button).
You could also do some automation to switch back to sun mode and specify kelvin and brightness.


#148

Yes, that’s what I thought. My problem is that it’s double wall switch (Aqara one) and I only have one button I can use for the ceiling lamp. So I have to use toggle :frowning:

If I make automation that changes back to normal (which is sun) it also turns the lamp on. That behavior just doesn’t work in my case.


#149

For RGB: I can test if you want. What needs to be changed in the library? The support for the background light is missing, right?

For UI element to switch between moon/normal mode (@mouth4war):
To check if the ceiling light is in moonlight, use bulb.get_properties(["nl_br"]). It will return 0 if not in moonlightor [1…100] if in moonlight


#150

ambilight for 650 is cool. I can test it too if anyone need.

@syssi: latest dev is causing exceptions.

#152

Could you post your configuration? You’ve defined a model called “rgb”, right?


#153

I think I misinterpreted the exception. Paste above.

Config:

light:
  - platform: yeelight
    devices:
      192.168.31.140:
        name: Kitchen Ceiling Lamp
        use_music_mode: False
        model: ceiling1
        transition: 350

#154

Your interpretation was fine. I fixed the error and prepared a PR now:


#155

Tested here and it works fine now.


#156

Anyone can explain me how to use “light.yeelight_set_mode” for set an rgb value to a turned on light?


#157

The turn_on service is what you’re looking for: https://www.home-assistant.io/components/light/


#158

I’m not at home for testing, so I ask: does it work also if light is already turned on?


#159

Yes. You can call turn_on multiple times with different configuratins / data sets.


#160

Could someone post an automation example with:
light.yeelight_set_mode {"mode": 5, "entity_id": "light.ceiling"} ??

:thinking:
