Danfoss Thermostat
Pair the thermostat like normal. When Vera shows the thermostat, tell Vera what room it's in and set the desired wakeup interval and any other options. Then save your changes. After the save, Vera will probably show the thermostat with the red cog (meaning it's not configured), press the activate button on the thermostat to wake it up. Vera should then be able to configure it, and show you the green cog. The 'Off' button puts the thermostat in 'energy saving' (ie night) mode, and the 'On' in 'normal' (ie day) mode. Note that the thermostat only wakes up periodically to accept commands. So wen you press off or on, the command is queued until the next time the thermostat wakes up. You can reduce the wakeup interval so the wakeups or more often (click the + button on Vera's device page), but note that it will reduce battery time, and you must save your changes, then after Vera comes back, press the 'activate' button on the thermostat to wake it up manually so Vera can configure it.
