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 Mode	Description
onOffStatus	Switch	R/W	Switches On or Off the unit
indoorTemperature	Number:Temperature	R	Indoor temperature from the Thermostat
outdoorTemperature	Number:Temperature	R	Outdoor temperature from the external unit. Not always supported/reported.
commCtrlVersion	String	R	Communication Controller Firmware Version
remoteCtrlVersion	String	R	Remote Controller Firmware Version
operationMode	String	R/W	The operation mode of the AC unit. Currently supported values: HEAT, COOL.
fanSpeed	Number	R/W	This is a "virtual channel" : its value is calculated depending on current operation mode. It is the channel to be used to change the fan speed, whatever the current mode is. Fan speed are from 1 to 5. On BRC1H, the device supports 3 speeds: LOW (1), MEDIUM (2-4), MAX (5).
setpoint	Number:Temperature	R/W	This is a "virtual channel" : its value is calculated depending on current operation mode. It is the channel to be used to change the setpoint, whatever the current mode is.
homekitCurrentHeatingCoolingMode	String	R	This channel is a "virtual channel" to be used with the HomeKit add-on to implement Thermostat thing. Values supported are the HomeKit addon ones: Off, CoolOn, HeatOn, Auto.
homekitTargetHeatingCoolingMode	String	R/W	This channel is a "virtual channel" to be used with the HomeKit add-on to implement Thermostat thing. Values supported are the HomeKit addon ones: Off, CoolOn, HeatOn, Auto.

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.
