Impossible to slowly turn on Silvercrest/Livarno/TuYa lights (transition)

Hardware
1

Greetings,

I’ve a couple of Silvercrest/TuYa lights (e.g. LIVARNO LUX (Lidl) model HG06106B), but it seems they have forgotten to add the dim feature.

Setting the brightness to 50% works and also using the gauge to manually adapt the brightness works fine as well. Then I tried the following Script:

lidl_e14_on_20sec:
  alias: switch on 20sec
  sequence:
    - service: light.turn_on
      data:
        transition: 20
      entity_id: light.lidl_e14_light
  mode: single

The light directly turns on with 100% brightness. I’ve used the same code, just with the entity ID of a Hue P40 light bulb instead and it worked fine.

Does this mean that the Lidl lights are not capable of slowing turning on or do I miss something?

Thanks,
Fridolin

I’m having the same issue and can’t figure out a solution either, did you manage to get it sorted?

I use the following code:

  action:
    service: homeassistant.turn_on
    entity_id: light.landing_lamp
    data_template:
      brightness:
        "{% if now().hour > 20 %}20{% elif now().hour < 8 %}50{% else %}255{% endif %}"

This sets the brightness to 20% if after 8pm.

What’s actually happening, is that it turns to 100% and then down to 20%, which is a bit jarring on a night. It replaced a Yeelight that was more than capable.

Unfortunately not. Before those Livarno lights, I’ve used a Hue light bulb, but this one behaved like you described. It turn on to 100% and directly dropped to 20%. This flash was quite annoying, so the expensive Hue is now useless in a box and the cheap Lidl lights are more or less working. Not as expected, like described above, but at least better than the Hue.

Just found this, so I have all my Lidl lights activated by motion sensor and the flash is starting to bother me. It didn’t for a while but when the landing light is flashing outside my bedroom at 10pm.

Am I right in thinking you partially solved the flashing, just not the transitioning on?

Unfortunately not. I just got rid of the flashing by replacing the expensive Philips Hue light bulb with a much cheaper Lidl light. Now there is no flashing anymore, but still I cannot tell the assistant to turn on the light from 0 to 100 in like 10 seconds or so. It softly turns on, no matter what I set as transition values - but that’s okay for me. I got used to it.

Hearing that you’ve the same problem with a Lidl device while I’m currently using four of them without any issues, makes me think it could be a hardware defect.
I never really confirmed that properly, but I remember that the flashing effect was minimized in case the blub was warm. So just turning on the light for like 15 mins and then switching it off and back on happend without flashing. It is the same on your side?

Well I have all lidl bulbs hooked up through the hue app, was wondering whether that was the issue and if perhaps they’d work better via zigbee. I need to have a look into it but it’s all lights.

So the motion sensor operates via zigbee dongle but sends signal to hue bridge, I have a feeling that’s the issue

Another way around this is to have an automation briefly set the bulbs to 20% at 3pm if they are off, then flip them back off again.

You won’t notice the flash as it’s daylight, and if you call them to turn on at 20% at 8pm and they’re still off, they’re likely to come alive at that setting.
