BLE2MQTT

Control your Bluetooth devices with smart home

Supported devices:

Any device

Any bluetooth device can work as a presence tracker You can provide "threshold" parameter to the device to set the limit in second when the device is considered away. The default value is 180 seconds.

Kettles

Redmond RK-G2xxS series (type: redmond_rk_g200)

The default key that is used is "ffffffffffffffff" and can be omitted in the config. In some cases kettles don't accept it. Just use another key in the config file for the device: "key": "16 random hex numbers"
Mi Kettle (type: mikettle)

Use correct product_id for your kettle:
- yunmi.kettle.v1: 131
- yunmi.kettle.v2: 275 (default)
- yunmi.kettle.v7: 1116

Multi-Cookers

Redmond RMC-M225S, RMC-M227S (type: redmond_rmc_m200)

Notes about the key parameter you can read above for the Redmond kettles. Other RMC multi-cookers may need adjustments for the list of available programs, it depends on the device panel.

Humidity sensors

Xiaomi MJ_HT_V1 (type: xiaomihtv1)
Xiaomi LYWSD02MMC (type: xiaomihtv1)
Xiaomi LYWSD03MMC (type: xiaomilywsd) (due to the connection to the device on every data fetch, it consumes more battery power. Flashing to the custom firmware is recommended)
Xiaomi LYWSD03MMC with custom ATC firmware (xiaomilywsd_atc)
- supported both atc1441 and pvvx formats

Air sensors

Vson WP6003 (type: wp6003)

Shades and Blinds

Generic AM43 (type: am43)

Manufacturer can be A-OK, Zemismart, etc.
Soma Shades (type: soma_shades)

Bulbs

Avea RGBW bulbs (type: avea_rgbw)

Dosimeters

Atom Fast (type: atomfast)

Heaters

Ensto EPHBEBT10PR, EPHBEBT15PR (type: ensto_thermostat)

These devices require manual pairing. After the device is paired on the host device, see the logs for the key and put it to the config.

The adapter uses holiday mode to control temperature as thermostat. You cannot use this feature in the official app while ble2mqtt is working.

By default, a device works in the passive mode without connection by listening to advertisement packets from a device. To use connection to the device provide "passive": false parameter.

Supported devices in passive mode:

Xiaomi MJ_HT_V1 (xiaomihtv1)
Xiaomi LYWSD03MMC with custom ATC firmware (xiaomilywsd_atc)
Any device as presence tracker

Manual pairing in Linux

Some devices (e.g. Ensto heaters) require paired connection to work with it. You need to pair the device with linux machine before using it.

Find out MAC addresses of your devices. Put the device in pairing mode if it is supported.

Open console and run bluetoothctl command. It is a command line tool to work with BLE devices. Wait for the prompt

[bluetooth]#

Print a command to enable scanning. Linux must know the device is present before pairing.

[bluetooth]# scan on

Wait for MAC address of the device appears in the list of found devices. Print a pairing command (replace MAC address to the one from your device)

[bluetooth]# pair 90:fd:00:00:00:01

On successful pairing you'll see a message:

[CHG] Device 90:FD:00:00:00:01 Paired: yes
Pairing successful

You can proceed with the next configuration steps now.

Known issues:

High cpu usage due to underlying library to work with bluetooth

Use this software at your own risk.

Configuration

Default config should be located in /etc/ble2mqtt.json or can be overridden with BLE2MQTT_CONFIG environment variable.

Example run command:

BLE2MQTT_CONFIG=./ble2mqtt.json ble2mqtt

The configuration file is a JSON with the following content:

{
    "mqtt_host": "localhost",
    "mqtt_port": 1883,
    "mqtt_user": "",
    "mqtt_password": "",
    "log_level": "INFO",
    "devices": [
        {
            "address": "11:22:33:aa:cc:aa",
            "type": "presence"
        },
        {
            "address": "11:22:33:aa:bb:cc",
            "type": "redmond_rk_g200",
            "key": "ffffffffffffffff"
        },
        {
            "address": "11:22:33:aa:bb:c0",
            "type": "redmond_rmc_m200",
            "key": "ffffffffffffffff"
        },
        {
            "address": "11:22:33:aa:bb:c1",
            "type": "ensto_thermostat",
            "# see logs after pairing and put the key to config": "",
            "key": "00112233"
        },
        {
            "address": "11:22:33:aa:bb:cd",
            "type": "mikettle",
            "product_id": 275
        },
        {
            "address": "11:22:33:aa:bb:de",
            "type": "am43"
        },
        {
            "address": "11:22:33:aa:bb:dd",
            "type": "xiaomihtv1"
        },
        {
            "address": "11:22:34:aa:bb:dd",
            "type": "xiaomihtv1",
            "passive": false
        },
        {
            "address": "11:22:33:aa:bb:ee",
            "type": "xiaomilywsd"
        },
        {
            "address": "11:22:33:aa:bb:ff",
            "type": "xiaomilywsd_atc"
        },
        {
            "address": "11:22:33:aa:aa:aa",
            "type": "atomfast"
        }
    ]
}

You can omit a line, then default value will be used.

Extra configuration parameters:

"base_topic"- the default value is 'ble2mqtt'
"mqtt_prefix"- a prefix to distinguish ble devices from other instances and programs. The default value is 'b2m_'.
"hci_adapter" - an adapter to use. The default value is "hci0"

Devices accept friendly_name parameter to replace mac address in device names for Home Assistant.

Systemd unit file to start on boot

Put the following content to the unit file /etc/systemd/system/ble2mqtt.service

[Unit]
Description=ble2mqtt bridge

[Service]
Type=Simple
ExecStart=/usr/local/bin/ble2mqtt
User=ble2mqtt
Group=ble2mqtt
Wants=bluetooth.target

[Install]
WantedBy=multi-user.target

The user and group should match the owner and group of the configuration file /etc/ble2mqtt.json.

Afterwards you simply have to enable and start the service:

sudo systemctl daemon-reload
sudo systemctl enable ble2mqtt
sudo systemctl start ble2mqtt

Installation on OpenWRT

Execute the following commands in the terminal:

opkg update
opkg install python3-pip python3-asyncio
pip3 install "bleak>=0.11.0"
pip3 install -U ble2mqtt

Create the configuration file in /etc/ble2mqtt.json and append your devices.

Bluetooth must be turned on.

hciconfig hci0 up

Run the service in background

ble2mqtt 2> /tmp/ble2mqtt.log &

Add a service script to start:

cat <<EOF > /etc/init.d/ble2mqtt
#!/bin/sh /etc/rc.common

START=98
USE_PROCD=1

start_service()
{
    procd_open_instance

    procd_set_param env BLE2MQTT_CONFIG=/etc/ble2mqtt.json
    procd_set_param command /usr/bin/ble2mqtt
    procd_set_param stdout 1
    procd_set_param stderr 1
    procd_close_instance
}
EOF
chmod +x /etc/init.d/ble2mqtt
/etc/init.d/ble2mqtt enable
/etc/init.d/ble2mqtt start

Running on Xiaomi Zigbee Gateway

Due to small CPU power and increasing number of messages from bluetoothd it is recommended to do several workarounds:

Use passive mode for those sensors for which this is possible. E.g. use custom ATC firmware for lywsd03mmc sensors
Restart bluetoothd daily and restart ble2mqtt several times a day to reduce increasing CPU usage. Put the following lines to the /etc/crontabs/root

10 0,7,17 * * * /etc/init.d/ble2mqtt restart
1 4,14 * * * /etc/init.d/bluetoothd restart

Running in Container

Build the image as:

podman build -t ble2mqtt:dev .

Start the container and share the config file and DBus for Bluetooth connectivity:

podman run \
-d \
--net=host \
-v $PWD/ble2mqtt.json.sample:/etc/ble2mqtt.json:z \
-v /var/run/dbus:/var/run/dbus:z \
ble2mqtt:dev

Instead of sharing /var/run/dbus, you can export DBUS_SYSTEM_BUS_ADDRESS.

NOTE: --net=host is required as it needs to use the bluetooth interface

NOTE: podman is the same as docker

Running in Container FULLy

ATTENTION: Make sure bluez is not running (or not intalled) on your host.
