It is rather what I can not find in the Controllers:
A control for exterior roller shutter that can then be automated using a light sensor.
It is a specific set of 3 buttons:
In addition to an analog proportional control for control based on %, dimmer type, or picker wheel…
It’s not very hard to make. It’s just three buttons. I control lights using a lightsensor, so that’s very doable and the buttons shouldn’t be much harder.
But the arrow buttons I think are a good idea, but that’s more of a userinterface thingie than a specific function.
You can use arrow emoji on the buttons
You can use emojis from keyboards.
Is there a list of available emojis somewhere?
Download any keyboard from play store which contains no. Of emojis.
This is a example I am using now from EasyIoT controller
