Homebridge Daikin Airbase

A Homebridge plugin providing support for the Daikin Airbase WiFi module (BRP15B61).

It allows to turn on/off the aircon, set it to cool/heat/fan/dry/auto mode (when supported), change the target temperature and the fan speed.

Daikin devices will be auto-discovered on the network and mapped to individual accessories in the Home app. Each device will be represented as an accessory group with:

A heater/cooler service allowing to set the aircon to cool/heat or auto mode, as well as the threshold temperatures,
A switch allowing to turn on/off fan mode,
A fan service allowing to change the aircon's fan speed (low/medium/high) if your device supports changing fan speed,
A second switch allowing to turn on/off dry mode if your device supports that mode.

In addition, if your system includes a Daikin Zone Controller, zones will be auto-discovered and mapped to an additional accessory group, with one switch for enabling/disabling each zone.

Requirements

Node version 11 or above (verify with node --version).
Homebridge version 1.0.0 or above.

Installation

Install homebridge using:

npm install -g homebridge

Install the plugin using:

npm install -g homebridge-daikin-airbase

Update your configuration file. See bellow for a sample.

Note: it is also possible to install this plugin in a local npm package instead using the homebridge option --plugin-path.

Configuration

General settings

To configure homebridge-daikin-airbase, add the DaikinAirbase platform to the platforms section of your homebridge's config.js file:

{
    "bridge": { "...": "..." },

    "description": "...",

    "platforms": [
        {
            "platform": "DaikinAirbase",
            "name": "Daiking Airbase"
        }
    ]
}

With the above configuration, the platform will perform UDP auto-discovery of the Daikin devices on the local network.

The platform can be configured with the following parameters:

Parameter	Type	Default	Note
`hostname`	String or Array(String)	`null`	Optional - The hostname(s) on your local network of the Daikin Airbase modules (e.g. `192.168.1.10`). Supports a single hostname as `String` or multiple hostnames in an `Array`.
`pollingInterval`	Number (minutes)	`5`	Optional - The polling interval for refreshing the platform's accessories state for automations, in minutes. By detault set to 5 minutes, it can be set to `0` to disable polling. Note that the information is refreshed on demand when using the Home app, this configuration is only used for background state updates so that automations can react on them.
`useIndividualZoneControls`	Boolean	`false`	Optional - Defines whether to map each zone switch to an individual accessory when a Daikin Zone Controller is available (`true`), or to map all zone switches to a single grouped accessory (`false`, default).
`overrides`	Object or null	`null`	Optional - Allows to override Daikin Airbase property values. If left undefined, property values retrieved from the Airbase will be used. Use at your own risk. See below for supported overrides.
`overrides.fanRateSupported`	Boolean	N/A	Optional - Define to override the ability to change the fan speed.
`overrides.fanModeSupported`	Boolean	`true`	Optional - Define to override the ability to control the aircon's fan mode.
`overrides.dryModeSupported`	Boolean	N/A	Optional - Define to override the ability to control the aircon's dry mode.

Notes

Accessory order

While the platform adds the different accessories in a specific order, the actual display order in the Apple Home app cannot be controlled by the plugin. You may find that accessories are not sorted in the order you expected. An easy work around for that situation is to simply rename the accessories inside the Home app to suit your needs.

Accessory caching

Once the platform has discovered an airbase module on the network, either through auto-discovery or static IP mapping, it will create the associated homekit accessories. These accessories will then be cached by homebridge.

As a safeguard, the platform will never unregister accessories if they cannot be contacted anymore. In consequence, if you are removing an airbase module from your network, you will have to clear the accessory cache of the homebridge-daikin-airbase plugin manually to unmap the unused accessories.

Accessories also cache their settings. This means that certain technical properties of your Daikin system will not be reflected on the accessories instantly after they are changed (for instance, Zone Controller names, maximum temperature, number of fan speeds, etc.). Restarting the homebridge server twice will ensure that the accessories use an up to date cache for these values.
