Closed domotica platform of the week. Technical information is simply non-existent on the website. When will there be a system which is, * open protocol, open implementation * incrementally affordable, i.e., add as you go * actually smart and not just a bunch of toggles in an app interface. Nest's learning thermostat is not what qualifies as smart in my book * Self hosted; no I don't want Google to know when I turn on my thermostat -- and no, I don't want my thermostat to be useless just because the cloud is having a bad day. So far I'm using OpenHAB with ZWave modules. This setup qualifies just half of the above, but at least it's stable and I can compose my system of components which I want.
