Nest Binding Example

Nest Binding Example

The contents of nest.items and nest.sitemap demonstrate a possible user interface that's backed by the Nest binding.

nest.items

The items file assumes your structure is called "Home," your thermostat is called "Dining Room," and you have two Nest Protects called "Upstairs" and "Basement." Change these to match how your devices are named at nest.com.

nest.sitemap

The sitemap will show the ambient temperature in the same scale (C or F) that the thermostat is set to. It will only show the away temperature range if the structure is currently in away mode. It will show the single setpoint if the thermostat is either in "heat" or "cool" mode, or will show the low and high setpoints if the thermostat is in "heat-cool" (auto) mode. The smoke+CO detectors show their status colors in the same color as the Nest Protect's light ring.

Rules

Opening Windows, set the Thermostat to away-mode to save Energy

This rule assumes that the windows are all Contact Items, are all in a Group called GWindow, and that the members are Bedroom2ZoneTripped ... StairsWindowsZoneTripped per the list below.

rule "Windows Opened (any)"
  when
    Item Bedroom2ZoneTripped changed from CLOSED to OPEN or
    Item Bedroom3ZoneTripped changed from CLOSED to OPEN or
    Item FamilyRoomZoneTripped changed from CLOSED to OPEN or
    Item GuestBathZoneTripped changed from CLOSED to OPEN or
    Item KitchenZoneTripped changed from CLOSED to OPEN or
    Item LivingRoomZoneTripped changed from CLOSED to OPEN or
    Item MasterBath1ZoneTripped changed from CLOSED to OPEN or
    Item MasterBath2ZoneTripped changed from CLOSED to OPEN or
    Item MasterBath3ZoneTripped changed from CLOSED to OPEN or
    Item MasterBedroomZoneTripped changed from CLOSED to OPEN or
    Item StairsWindowsZoneTripped changed from CLOSED to OPEN
  then
    if (GWindow.members.filter(s|s.state==OPEN).size == 1) {
      home_away.sendCommand("away")
    }
end

Closing Windows, set the Thermostat to home-mode when all windows are closed

As the counterpart of the above rule, set the Thermostat to home once all the windows are closed.

rule "Windows Closed (all)"
  when
    Item Bedroom2ZoneTripped changed from OPEN to CLOSED or
    Item Bedroom3ZoneTripped changed from OPEN to CLOSED or
    Item FamilyRoomZoneTripped changed from OPEN to CLOSED or
    Item GuestBathZoneTripped changed from OPEN to CLOSED or
    Item KitchenZoneTripped changed from OPEN to CLOSED or
    Item LivingRoomZoneTripped changed from OPEN to CLOSED or
    Item MasterBath1ZoneTripped changed from OPEN to CLOSED or
    Item MasterBath2ZoneTripped changed from OPEN to CLOSED or
    Item MasterBath3ZoneTripped changed from OPEN to CLOSED or
    Item MasterBedroomZoneTripped changed from OPEN to CLOSED or
    Item StairsWindowsZoneTripped changed from OPEN to CLOSED
  then
    if (GWindow.members.filter(s|s.state==OPEN).size == 0) {
      home_away.sendCommand("home")
    }
end
