Local Daikin Integration

This is a full integration for Daikin air conditioners using local network access. It includes UI-based setup and supports climate control, switches, selects, and sensors. Built quick and dirty as a bridge until we have a better solution available, this custom integration allows you to connect Daikin air conditioners, specifically those running firmware version 2.8.0, to Home Assistant. It serves as a temporary solution to ensure compatibility until the official Home Assistant team can address the issue.

🔧 Installation

1. Copy the local_daikin folder into your Home Assistant custom_components directory:

   <config>/custom_components/local_daikin/
   

2. Restart Home Assistant.

3. Go to: Settings → Devices & Services → Add Integration → Local Daikin

4. Enter the IP address of your Daikin air conditioner.

Features

• Full climate control (temperature, HVAC mode, fan, swing)
• Extra entities:

  • Switches: Power, Quiet Fan, Swing Mode

  • Select: HVAC Mode Fan Speed, Swing Mode

  • Sensors: Outdoor temperature, energy today, runtime today indoor temp, humidity

  • Sensor: Target temperature (Not programming only, not in UI, Null if not applicable due to HVAC Mode)

Notes

• If upgrading from v0.0.5 (or earlier), you will need to delete the manual configuration in your configuration.yaml and reconfigure via the Home Assistant devices panel.
• Ensure your Daikin unit is on the same network as Home Assistant.
• Communicates with the /dsiot/multireq endpoint on your device.

Compatibility

This integration has been tested and confirmed to work with the following Daikin models:

• FTKM20YVMA with firmware version 2.8.0.
• FTXM46WVMA with firmware version 2.8.0.

Compatibility with other models or firmware versions is not guaranteed. I keep my own units on firmware 2.8.0 and haven’t upgraded because I don’t want to risk breaking anything.

Feedback and Contributions
