I am very dissapointed as well, I was super excitied about these buttons and I have in between my order and when I got them significantly invested in to my small 2 bedroom apartment in terms of smart home functionality. I added smart thermostats, replaced more lights added way more RGB than is usefull to the "gaming room" combining govee and hue lights as well as smart humidifiers etc. it can all be controlled through home assistant.
I was ready to have physical buttons to control all of this again, it would make it so much easier on my wife in particular. We are SOOOO much further along now even after the kickstarter, and there is still no message other than "our priority is matter blah blah" IF that is your priority: where is it? It doesn't support dimmers? Then WHY is it your priority given that "twist" is literally in the name and dimming is the right thing to do. You COULD add SDK support until Matter figures things out but there is a flat out refusal to make it usable. It is sad and I make sure that anyone discussing this knows how poor the support for this product is.
