Totally get it. I’m often frustrated by this kind of “good hardware bad software” experience, and kinda hate the “install our crappy app” push. What I would like to see is companies doing what they do best (in this case, a thermostat builder making a good thermostat), and leaving the rest of it (like mobile/web/control apps) to those who do it better. What we see in practice though is that business don’t want to create an ‘interface’ for interoperability (for fear that they may be replaced), but instead want to “control everything” end to end, which is why we see proprietary thermostat-to-air-handler protocols, and even encryption between garage door openers and the BUTTON on the wall to open your own garage door.
