| Control | Firmware capability |
|---|---|
| Modes | Off, Heat, Cool, Auto, Dry, and Fan. Additional modes beyond Apple Home's thermostat controls are available in the web interface. |
| Target temperature | Adjustments in 0.5°C increments; independent heat and cool targets in Auto mode. |
| Fan speed | Auto, Quiet, Low, Med, High, and Max. |
| Vertical vane | Auto, five fixed positions, and Swing. |
| Horizontal vane | Five fixed positions, Split, and Swing. |
| Room sensor | One source or an average of selected remote sources, with per-sensor offsets. See room temperature sensors. |
Apple Home has no vane controls; use the web interface. Remote access and automations require an Apple Home hub.
ESPHome standard entities
The standard build provides these Home Assistant entities. IDs follow your chosen name: living-room produces climate.living_room.
Scroll sideways to read all columns.
| Entity | Domain | Purpose |
|---|---|---|
| Indoor unit | climate | Mode, target temperature, fan speed, and current room temperature. |
| Vertical vane | select | Up-and-down airflow direction. |
| Horizontal vane | select | Left-and-right airflow direction. |
| LED | light | The board's RGB light. ESPHome assigns it no controller status function. |
| Button | binary_sensor | The controller's physical button. |
| Signal strength | sensor | Wi-Fi signal strength in decibels. |
| IP address and SSID | sensor | Network address and Wi-Fi network name. |
| ESPHome version | sensor | The ESPHome version used to compile the firmware. |
| Pair Serin Link | button | Opens the controller's pairing window for a Serin Link. |
| Room Temperature Source | select | Selects the built-in sensor or paired Serin Link. |
| Serin Link 1 device | binary_sensor, sensor | Connected, MAC, Last Seen, Firmware, Temperature, and Humidity for the paired Serin Link. |
Climate and vane options
- Modes: Off, Heat, Cool, Auto, Dry, and Fan.
- Temperature: 15 to 31°C in 0.5° increments, with room temperature displayed to 0.1°. The indoor unit's limits still apply.
- Fan speed: Auto, Quiet, Low, Medium, Middle, and High.
- Vertical vane: Auto, five positions, and Swing.
- Horizontal vane: five positions, Split, and Swing.
Auto mode uses one target by default. Separate heat/cool setpoints, swing on the climate entity, and Even/Indirect/Direct airflow are generator options. Omit the horizontal vane if the unit has none.
The generator can also add an i-See occupancy binary sensor, supported Night mode/Air purifier/Circulator switches, Bluetooth proxy, and ISU installer settings. See optional configuration features for requirements and installation.
Heat-pump diagnostic readings
See diagnostic readings or collect logs for support.
Matter controls in Google Home, Alexa, and SmartThings
The Matter thermostat provides power, Heat/Cool/Auto, target temperature and room temperature. Dry, fan-only, fan speed and vane controls may be absent from your app; use the web interface for those controls and diagnostics.
Unavailable settings
