Duration of Dimming / Morning Light (simulate sunrise as part of pimatic-led-light)

---

As part of the discussion on https://github.com/philip1986/pimatic-led-light/issues/27 @thymian mentioned the following idea:

“I am missing something like a morning light. People pay 200€ for these bulbs which dim up in about 30 min to emulate the sun rising. I once wrote a script myself but this was very bad written because i dont understand that promise programming and didn’t find out how [to] use for or while [loops]”

I’m missing a feature, whereby I can control my led light by saying “please dim my light from the current state to 100% within 5 minutes”. Any chance to realise it?

It’s a really good idea! guess it’s not only for “morning grouches” but also for aquaristics and reptiles / terraristic!
i could imagine that a reverted function as good night / sundown would be a nice feature too.

Shouldn’t that be possible by some rules?

if its 30 minutes before sunset set $someDevice.brightness = 75
if its 20 minutes before sunset set $someDevice.brightness = 50
if its 10 minutes before sunset set $someDevice.brightness = 25
if its sunset set $someDevice.brightness = 0

@SaxnPaule Your’re right, however, the “morning light” function would be easier to use and could use more dimlevels.

Dimming through the loop I used here:https://github.com/wutu/pimatic-piblaster/tree/development.
Among the steps inserted delay parameter. Perhaps it would be good to delay viewed directly in the interface.
Programmed it’s probably pretty awful, but it works.

Happy Christmas

Thanks for pointing this out. Nice project, btw. If you’re in favor of the “Morning Light” feature request, please upvote on the first post. Thanks!

Hi @mwittig,

well, I wouldn’t call it only “morning light” simulation because everyone could think it is only for this specific timeframe. It’s more a light fading. I have seen that @sweebee mentioned it is already implemented in the Hue plugin?!

Cheers and thank you,
Leopold

@leopoldkoenig its not include in the hue plugin, but the hue api does support it.

Agree. That’s why I have changed the title to calrify it is a multi-purpose dimming function

@sweebee ok, got it!

@mwittig thank you

I read for a lot of names , but fade is probably the most widely used.
Like this interesting MQTT dimmer.

For plugin - pimatic-piblaster, I used the name delay (i wrote this before one year).

I, for example, use it for lighting control within my fish tanks. With sunrise module can then be simulated for example, an entire solar cycle to be in Brasilia(I specialize in the Amazon region).

i ve for this, i hope you mean this, some rules

{
  "id": "lichtplus",
  "name": "LichtPlus_Morgens",
  "rule": "if its after 6:00 and before 7:00 and every 20 seconds and $rfswitch.dimlevel < 100 then dim Dimmer to $rfswitch.dimlevel +1",
  "active": true,
  "logging": true
},
{
  "id": "lichtminus",
  "name": "LichtMinus_Abends",
  "rule": "if its after 21:00 and before 22:00 and every 20 seconds and $rfswitch.dimlevel > 0 then dim Dimmer to $rfswitch.dimlevel -1",
  "active": true,
  "logging": true
},
{
  "id": "lichtminus-mittag",
  "name": "LichtMinus_Mittag",
  "rule": "if its after 10:00 and before 11:45 and every 10 seconds and $rfswitch.dimlevel > 0 then dim Dimmer to $rfswitch.dimlevel -1",
  "active": true,
  "logging": true
},
{
  "id": "lichtplus-nachmittag",
  "name": "LichtPlus_Nachmittag",
  "rule": "if its after 60 minutes before sunset and before 20:59 and every 10 seconds and $rfswitch.dimlevel < 100 then dim Dimmer to $rfswitch.dimlevel +1",
  "active": true,
  "logging": true
},

@noxx does that really work? It seems like sth I was thinking about!

yes, works…

i use this rules every day to simulate sunset and sunrise in my chicken house

awesome!

@noxx
Thx for sharing, brilliant rules for “morning light” it’s certainly usable.

I use LED softened. Better for the eyes . Therefore, from 0% to 100 % for example 2 seconds.
Step is 20 ms , and it does not work . I would say that rules are somehow limit.

In pimatic-piblaster I inserted for each 1% of pimatic dimmer 10 step for piblaster . So far it is not done very well , I am preparing an update.
