Deriva IntelliSync for Android
Adding devices using the Android app simply doesn't work. You connect to the thermostat in AP mode, hit back, and nothing happens. Whoever created this must be an iPhone user, because the iPhone app works fine. Very frustrating. Also, a completely identical rebrand of the Lux Products app.

The App works fine, but have trouble connecting my husbands phone to the thermostat as well. I get as far as contacting Deriva's servers and it can't connect with their servers even though after a couple hours I see in tech support he can control thermostat, but through his internet account with Deriva. Geofence can be used with 2 phones, but it appears that He can't control with his phone with the App, only by signing into his web account.
