Daikin One+ Thermostat Homebridge Plugin

HomeKit support for Daikin One+ thermostats using Homebridge

homebridge-daikin-oneplus uses the Daikin One+ API to allow native HomeKit support via Homebridge for any thermostats on your account.

Accessories and their features (dependent upon your system/equipment capabilities):

Thermostat
- Display current temperature
- Display and set target temperature
- Switch mode between cool, heat, and auto
- Set both cooling and heating threshold in auto mode
- Temporarily override a schedule
  - Schedule will be paused for a period of time based on how the thermostat is configured. The thermostat can be configured to pause for 1, 4, or 8 hours, or until the next event in the schedule.
- Air Quality sensors
  - Display indoor and outdoor levels
- Relative humidity sensors
  - Display indoor and outdoor levels
  - Set target indoor relative humidity
Schedule switch
- Display and set thermostat's schedule state
Away switch
- Display and set thermostat's away state
- Optionally, the schedule can be enabled automatically when the Away switch is toggled off. By default this plugin and the thermostat itself do not enable the schedule after returning from Away.
Emergency Heat switch
- Display and set thermostat's emergency/auxiliary heat state
One Clean fan
- Trigger the thermostat to run the fan for a 3 hour One Clean cycle
Circulate Air fan
- Allows the Circulate Air feature to be toggled between 'off' and 'always on'
- Fan speed can be adjusted:
  - 0% : Off
  - 33% : Low
  - 66% : Medium
  - 100% : High
Version 2+ improves performance in several ways:
- Reduce bandwidth by checking the Daikin API every 3 minutes or on demand when interacting with HomeKit (instead of the previous every 10s)
- After updates, wait up to 15 seconds before checking API to avoid HomeKit showing stale data.
Version 3
- Minimum node version increased to 14
- Plugin is now verified!

Known Issue

Per issue #20, it may now be necessary to request an integration token via the Daikin One Home app before this plugin can successfully communicate with the Daikin API.
- To get an integration token:
  - Open the Daikin One Home app
  - Go to account settings on the Location/root/top screen of the app.
  - Select home integration
  - Select get integration token
  - Agree to terms
  - Enter your account password
  - Select send request
- Once you receive the token, nothing further should be required.
- You may need to uninstall/reinstall the plugin, or at least restart Homebridge to get a successful connection.
