I have two of them and they work perfectly with the iOS app. I don't have android, so I cannot comment. It was working in R072 and continues to work perfectly with R076.
For the webUI (both, local and connect.securifi.com), there seems to be a CSS/JS issue that prevents any changes in the thermostat.
@Ashok, can you please have a look at the webUI issue when there are two thermostats connected ? Let me know if you can replicate it or not, because that would indicate something is wrong with my setup. This behavior has been there from R072 and persists in R076.
