Hello I am designing my home automation setup for our up and coming renovation.
One thing i really want to incorporate is dumb/smart switches for everything.
I played around in micropython and got a basic switch setup using 2 toggle buttons UP and DOWN with dimming by holding on the up/down button.
My only problem is trying to find a momentary wall switch that can act like a toggle up and down. I found some regular switches but I want the “decora” style.
This is the closest i found but its only momentary off

I was also thinking of a touch screen style switch but that might be a bit pricey but i am open to making a touchscreen slider 
Any ideas?
Thanks!
