Each device has a number of channels which automatically get assigned to a zone when the device is assigned to the zone. These are the different parts of the device which the system can interact with, such as receiving the measured temperature.
It is possible to add individual channels to a zone, such as if you want to share the measured temperature of your hot water tank between your boiler heated hot water zone and your electric immersion backup zone. For more information on assigning individual channels, see the 'Adding New Devices' chapter of the User Manual.
Below is each of the channels you may encounter and a brief description of them:
- Battery: The current battery level of the device. This should not be individually added to any zone.
- HEATING_1: The schedule for the device, adding this to a zone will mean that device follows the schedule of the zone it is assigned to, and any override triggered by this device will affect the zone. For example, if you put the HEATING_1 channel of a thermostat into multiple zones, manually overriding that thermostat will override all of the zones with this channel assigned.
- SwitchBinary: The ability to read and switch the relay of a device, such as a Smart Plug. This should not be added to more than 1 zone.
- TEMPERATURE: The temperature reported by the device, such as from a Thermostat or Room Sensor. This can be added to multiple zones, such as in the example above.
- LUMINANCE: Not used.
- Motion: The occupancy detection from a Room Sensor. This should not be assigned to more than one zone as only the first zone will react to the occupancy triggers.
