Nexia

The nexia component lets you control thermostats connected to Nexia (Trane/American Standard).

As of version 1.0.0 this library uses asyncio and aiohttp. The last version to use requests was 0.9.13.

All the set functions are no coroutines.

Supported XL950, XL1050, XL824 Not supported XL624, others

By connecting this component, you will have access to all thermostats and zones in your associated home.

Concepts

The Nexia Thermostat supports the following key concepts.

RoomIQ Sensors

You can obtain sensor details in a Nexia Thermostat environment. The sensor data loaded during Nexia Home update are often out of date. So the Nexia Thermostat Zone service load_current_sensor_state is provided to load current sensor state into the physical thermostat. Many existing thermostat instance services will refresh this sensor data before completing. If no such service is desired, the Nexia Thermostat service refresh_thermostat_data is provided to refresh instance data. The Nexia Thermostat Zone service get_sensors is provided to obtain these sensor data in a list of sensor detail data objects of type NexiaSensor. To get a specific sensor detail data object, the Nexia Thermostat Zone service get_sensor_by_id is provided.

You can specify which RoomIQ sensors to include in the zone average via the Nexia Thermostat Zone service select_room_iq_sensors. You can see which RoomIQ sensors are included in the zone average via the Nexia Thermostat Zone service get_active_sensor_ids. To help coordinate separate manual actions taken to select active sensors you can use the Nexia RoomIQ Harmonizer services trigger_add_sensor, trigger_remove_sensor, request_pending, async_shutdown.
