Hi
New to the forum, but have a few things on HA already
I am struggling with the logic of what I’m trying to achieve. I promise I have searched but I cannot find answer to what I’m trying to do - I admit though my search logic is probably all wrong and I apologise for asking what I know is a simple question
I have an LED connected to a WEMOS D1 MINI - HA turns it on at a random time during a one hour window before sunset. Pretty standard and works a treat… HA switches that LED off at 11.59pm
What I would like to do now is change the behavior of the switch off to use a PWM pin on the WEMOS so that in say a 1 hour window the LED gradually dims to nothing so would be off at 11.59
I am really struggling with the logic though. Simply turning on the LED is going to change, I need to send a command to the WEMOS to turn it on a PWM value 255. I don know how to do that. Even if I could figure that out however I then need to know how to send a PWM command at (for instance) 10pm to start dimming the light to 0 by 11.59 (this is maths - I’m sure I can figure it out)
I dont want HA to send out a message every 4 minutes to say ‘dim but int 4’ (for example).
Ideally I’d like to have a loop installed on the wemos which I can launch from HA at 10pm so start running?
In my head this should be so simple but I have obviously gone into some loop of stupidity
I’d really appreciate any help
Thanks for any help if you read this and think, clown!
