homebridge-tasmota-aircon-http

Control an aircon using a Tasmota powered infrared transmitter.

How it works

This Homebridge plugin will create a Heater Cooler service which can be controlled from HomeKit. When a parameter (like temperatur) is changed, a HTTP request will be sent to your Tasmota powered IR device, which again will send the appropriate IR codes to your air condition.

Here is an example on how the command can flow:

         [Homekit]            [HTTP]      [IR]
iPhone -> Homepod -> Homebridge -> Tasmota -> Aircon

The IR codes are sent in the HVAC format, meaning very little configuration is needed. Here are the parameters sent:

• Variables from Homekit
  • FanSpeed - RotationSpeed
  • Mode - TargetHeaterCoolerState
  • Power - Active
  • SwingV - SwingMode
  • Temp - CoolingThresholdTemperature and HeatingThresholdTemperature
• Configuration
  • Beep - true/false
  • Celsius - "C" or "F"
  • Light - true/false
  • Vendor - Daikon, Hitacho, Toshiba, ...
• Currently static
  • Clean - false
  • Econo - false
  • Filter - false
  • Model - "-1"
  • Quiet - false
  • Sleep - "-1"
  • SwingH - false
  • Turbo - false

Configuration

• Name (name) - Name of the service in Homekit
• URL to the Tasmota controller (tasmota_url) - URL to the Tasmota device on your local network.
• Remote control / Aircon vendor (vendor) - The vendor. Ex Daikon, Hitacho, Toshiba, ...
• Beep (beep) - Enable "beep" in the HVAC IR code.
• Light (light) - Enable "light" in the HVAC IR code.
• Enable the auto speed for Fan (fanautospeed) - Set if the plugin should use the speed auto of fan

Caveats

The protocol is just one way now, meaning that if you change the settings on the aircon with another infrared remote, then the settings will not be updated in Homekit.
