# DaikinMadoka

This extension implements communication with Daikin Madoka BRC1H thermostat over Bluetooth Low Energy (BLE) communication protocol. The device uses an UART over BLE serial communication protocol over BLE WriteWithoutResponse and Notify characteristics.

# Supported Things

Thing Type ID	Description
brc1h	BRC1H BLE Thermostat

# Discovery

As a pairing of the Thermostat is necessary (Bluetooth), no automatic discovery is implemented.

# Thing Configuration

address: The Bluetooth MAC Address of the BRC1H controller

Example with a DBusBlueZ Bluetooth Bridge:

Bridge bluetooth:dbusbluez:hci0 [ address="00:1A:7D:DA:71:13" ]

Thing bluetooth:brc1h:hci0:salon (bluetooth:dbusbluez:hci0)     [ address="00:CC:3F:B2:80:CA" ]

# Channels

Here you should provide information about available channel types, what their meaning is and how they can be used.

Note that it is planned to generate some part of this based on the XML files within src/main/resources/OH-INF/thing of your binding.

Channel Type ID	Item Type	Access	Description
onOffStatus	Switch	R/W	Turns the unit on or off.
indoorTemperature	Number:Temperature	R	Current indoor temperature reported by the thermostat.
outdoorTemperature	Number:Temperature	R	Outdoor temperature from the external unit (may not always be supported).
commCtrlVersion	String	R	Firmware version of the communication controller.
remoteCtrlVersion	String	R	Firmware version of the remote controller.
operationMode	String	R/W	Current operating mode of the AC unit. Supported values: `HEAT`, `COOL`.
fanSpeed	Number	R/W	Virtual channel for adjusting fan speed (independent of mode). Values: `1–5`. BRC1H units: `LOW (1)`, `MEDIUM (2–4)`, `MAX (5)`. Some models also support `AUTO (0)`.
setpoint	Number:Temperature	R/W	Virtual channel for adjusting the temperature setpoint (independent of mode).
homekitCurrentHeatingCoolingMode	String	R	Virtual channel for HomeKit integration (Thermostat thing). Supported values: `Off`, `CoolOn`, `HeatOn`, `Auto`.
homekitTargetHeatingCoolingMode	String	R/W	Virtual channel for HomeKit integration (Thermostat thing). Supported values: `Off`, `CoolOn`, `HeatOn`, `Auto`.
homebridgeMode	String	R/W	Virtual channel for HomeBridge integration. Supported values: `Off`, `Heating`, `Cooling`, `Auto`.
eyeBrightness	Dimmer	R/W	Adjusts the brightness of the blue “eye” indicator (`0–100%`).
indoorPowerHours	Number:Time	R	Total hours the indoor unit has been powered (operating or idle).
indoorOperationHours	Number:Time	R	Total hours the indoor unit has been actively operating.
indoorFanHours	Number:Time	R	Total hours the fan has been running.
cleanFilterIndicator	Switch	R/W	Indicates if the filter needs cleaning. Reset by writing `OFF` to this channel.

# Pairing the BRC1H

The Daikin Madoka BRC1H Thermostat requires Bluetooth Pairing before it can be used. This pairing process can be a bit challenging, as it seems the timing is very important for it success.

We suggest that the Bluetooth adapter is not being used by another component during the pairing phase. As such, if you have other Bluetooth Things in your OpenHAB, it is suggested to stop the openHAB service before doing the pairing.

Ensure that your BRC1H has Bluetooth enabled in the menu
Open bluetoothctl on your openHAB server - preferably as root
start scanning by typing scan on
After few seconds, stop scanning scan off
Start the pairing process by typing pair <mac address of your brc1h>
On the BRC1H, confirm the pairing request, and quickly confirm as well on your server by typing yes

A successful pairing ends with pairing successful.

For more information on pairing a device in command line on Linux, refer to official documentation (opens new window).
