How to dim a light?

I would like to fade out a light when I push a button, so the button is the trigger.
Iād like to set the level to 0% in a short but defined amount of time for example 3seconds
How can realize that with dzevents?
My lights are Yeelight so they support .dimTo() and my dzevents is 2.2.0
Thanks in advance

With current version of dzVents ( 2.4.5 ) you can dim using only native dzVents code with steps of 1 second using the afterSec() method. Look
here for an example. So if you want to do it in 3 seconds then it would not go very smoothly. As far as I understand there is no support yet for user defined smoothness in the domoticz code for the Yeelight hardware
(Yeelight.cpp) . If you could work out what the http string should be, It must be possible to call the Yeelight bulb with dzVents openURL.
Look for a solution with os.execute (described in the wiki)
Here
Or create a Python script using the package described
here and call that from a device's off and/or on action

you could do whatever action is possible with your yeelight bulbs.
python code to dim to zero in 15 seconds.. // Script needs Yeelight module; install with ==>> pip install Yeelight
Code: Select all
#!/usr/bin/python
from yeelight import discover_bulbs
from yeelight import Bulb
bulb = Bulb("nnn.nnn.nnn.nnn", effect="smooth", duration=15000) # 15 seconds
bulb.turn_off()

Yes but you will have to use the os.execute command
