My requirements: at least two buttons, small size.
What do you think is the best option for such item? DIY or already existing product? If DIY which platform and wireless protocol to choose?
I know my question very broad, I’m just interesting what is current trend in this stuff.
Actually I found many different smart buttons, but many of them have just one button, which is kinda lame.
For something that does not require programming and works reliably I wound up going with Lutron Caseta remotes - I bought the pro hub just to use the remotes, but it was worth it. 5 buttons on each Pico remote, they are wall mountable, $15 each. But if you’re going to do it use the custom component integration would be my recommendation rather than the built in one.
Is ZigBee an option? If yes, I can highly recommend the Hue Dimmer Switches integrated over DeConz. 4 buttons, each button has short press, short press release, long press and long press release and they are cheap as well.
