MQTT client to control BroadLink devices

Installation

Clone broadlink-mqtt repository using
git clone https://github.com/eschava/broadlink-mqtt.git
or download and unpack latest archive from
https://github.com/eschava/broadlink-mqtt/archive/master.zip

Ensure that a python development environment is setup: sudo apt-get install python-pip python-dev

Ensure that the libffi-dev and libssl-dev packages are installed: sudo apt-get install libffi-dev libssl-dev

From the newly created broadlink-mqtt folder, install the required Python modules: pip install -r requirements.txt

Configuration

By default, broadlink-mqtt will configure using parameters from mqtt.conf. This configuration file may be altered during a repository update, so another configuration file is provided for editing: custom.conf. This will not be overwritten when updating broadlink-mqtt.

custom.conf overrides mqtt.conf. Copy the contents of mqtt.conf into custom.conf and continue editing only custom.conf.

Recorded commands are saved under the commands/ folder
Macros are saved under the macros/ folder

Multiple devices configuration

Usually broadlink-mqtt works with single Broadlink device only, but there is an experimental feature to support several devices connected to the same network.
Configuration parameters:
device_type = 'multiple_lookup'
mqtt_multiple_subprefix_format = '{type}_{mac_nic}/'
Second parameter defines format of sub-prefix for every found device. E.g. for RM2 device having MAC address 11:22:33:44:55:66, MQTT prefix will be
broadlink/RM2_44_55_66/
Format supports next placeholders:

  • {type} - type of the device (RM2, A1, etc)
  • {host} - host name of the device
  • {mac} - MAC address of the device
  • {mac_nic} - last 3 octets of the MAC address (NIC)

Connect Broadlink device to wifi

You need to use the Broadlink e-control app or Broadlink Intelligent Home Center to get the device connected to wifi. Don't use BroadLink -Universal TV Remote, as it is known to lock devices. Other apps have not been tested.

Press the reset-button for 5+ seconds till the led starts flashing continuously. Now it is in "smart mode". Go to the e-control or Intelligent home Center app and add a new device. Fill in the wifi-credentials and start scanning while staying close to the device. When the led starts flashing slower, it is discovered. When the led turns off, it is configured.

You (theoretically) can configure multiple devices at one.

Start

Just start mqtt.py script using Python interpreter. You may have to use python3.

Auto-startup (Linux)

(From eschava#29 (comment))

sudo nano /lib/systemd/system/broadlink-mqtt.service

Copy and paste the following, then save:

[Unit]
Description=Broadlink MQTT Service
After=multi-user.target
[email protected]

[Service]
Type=simple
ExecStart=/usr/bin/python3 /home/pi/broadlink-mqtt/mqtt.py
StandardInput=tty-force

[Install]
WantedBy=multi-user.target

Reload the daemon: sudo systemctl daemon-reload

To start the service:
sudo systemctl start broadlink-mqtt.service

To see the service status:
sudo systemctl status broadlink-mqtt.service

To stop the service:
sudo systemctl stop broadlink-mqtt.service

To restart the service:
sudo systemctl restart broadlink-mqtt.service

Error messages

  • ERROR No Broadlink devices found: No wifi-device on the network is a Broadlink device recognized by the library. If you see a device connected to your wifi that starts with the device type, like "RM4-44-b6-a2" for a RM4, then it could be that the device is not supported yet. If you see no device connected (which is in most cases), make sure it is connected to your wifi network.
  • broadlink.exceptions.AuthenticationError: Authentication failed: The device is locked by an app. Use the instructions above to reset the device and connect it to wifi without lock.
  • with socket.socket(socket.AF_INET, socket.SOCK_DGRAM) as s: AttributeError: exit: this library requires Python3, and you used Python2. Start the library with python3 ./mqtt.py.
  • ERROR MQTT topic broadlink/RMx_xx_xx_xx/projector/power has no recognized device reference, expected one of RMy_yy_yy_yy/: replace the device ID RMx_xx_xx_xx with RMy_yy_yy_yy in your mqtt-command.
  • FileNotFoundError: [Errno 2] No such file or directory: '/opt/broadlink-mqtt/commands/projector/power': You need to manually create a directory per device.
  • WARNING OOOOPS! MQTT disconnection: It happens

If you think you see reasons to improve the library, you are very welcome to contribute!

RM2/RM3/RM4

MQTT commands to control IR/RF

Recording (IR or RF)

To record new command just send record message for IR command or recordrf for RF command to the topic broadlink/COMMAND_ID,
where COMMAND_ID is any identifier that can be used for file name (slashes are also allowed)

NOTE: It seems that Python3 is a must for recording RF signals

Example: to record power button for Samsung TV send
record -> broadlink/tv/samsung/power
and recorded interpretation of IR signal will be saved to file commands/tv/samsung/power

Replay

To replay previously recorded command send replay message to the topic broadlink/COMMAND_ID,
where COMMAND_ID is identifier if the command
Example: to replay power button for Samsung TV send
replay -> broadlink/tv/samsung/power
and saved interpretation of IR signal will be replayed from file commands/tv/samsung/power

Another format for replaying recorded command is using file name as a message and folder as MQTT topic.
Example: to replay power button for Samsung TV send
power -> broadlink/tv/samsung
and saved interpretation of IR signal will be replayed from file commands/tv/samsung/power

Smart mode

Smart mode means that if file with command doesn't exist it will be recorded.
Every next execution of the command will replay it.
This mode is very convenient for home automation systems.
To start smart mode need to send auto for IR command or autorf for RF command to the command topic
Example:
first time: auto -> broadlink/tv/samsung/power records command
every next time: auto -> broadlink/tv/samsung/power replays command

Macros

Macro command sends several IR signals for single MQTT message.
To start macros execution send macro message to the topic broadlink/MACRO_ID,
where MACRO_ID is a path to scenario file in macros/ folder.
Alternative way of sending macro command is sending MACRO_ID message to the broadlink/macro topic.

Macros scenario file could contain:

  • IR commands (same as COMMAND_ID in replay mode)
  • pause instructions (pause DELAY_IN_MILLISECONDS)
  • comments (lines started with #)

Subscription to current temperature (RM2/RM4 devices)

Need to set broadlink_rm_temperature_interval configuration parameter to a number of seconds between periodic updates.
E.g. broadlink_rm_temperature_interval=120 means current temperature will be published to topic broadlink/temperature every 2 minutes

SP1/SP2

MQTT commands to control power

To switch power on (off) need to send command on (off) to broadlink/power topic
Commands 1 / 0 are also supported

Subscription to current used energy (SP2 device)

Need to set broadlink_sp_energy_interval configuration parameter to a number of seconds between periodic updates.
E.g.
broadlink_sp_energy_interval=120
means current used energy will be published to topic broadlink/energy every 2 minutes

A1

Subscription to current sensors data

Need to set broadlink_a1_sensors_interval configuration parameter to a number of seconds between periodic updates.
E.g.
broadlink_a1_sensors_interval=120 means current sensors data will be published to topics broadlink/sensors/[temperature/humidity/light/air_quality/noise] every 2 minutes

MP1

MQTT commands to control power

To switch power on (off) on outlet number N need to send command on (off) to broadlink/power/N topic.
Commands 1 / 0 are also supported
Example:
switch on 2-nd outlet: on -> broadlink/power/2

Subscription to current state

Need to set broadlink_mp1_state_interval configuration parameter to a number of seconds between periodic updates.
E.g.
broadlink_mp1_state_interval=120
means current state will be published to topics broadlink/state/[s1/s2/s3/s4] every 2 minutes

Dooya DT360E

MQTT commands to control curtain motor

To open/close curtains need to send a command to broadlink/action topic.
Possible commands are:

  • open to open curtains
  • close to close curtains
  • stop to stop curtains in the current state

Also it's possible to set fixed position of curtains sending numeric position in percents to the topic broadlink/set

Subscription to current curtain position

Need to set broadlink_dooya_position_interval configuration parameter to a number of seconds between periodic updates.
E.g.
broadlink_dooya_position_interval=30
means current curtain position in percents will be published to topic broadlink/position every 30 seconds

BG1

MQTT commands to control

To change brightness of LED need to send value in percents to broadlink/brightness topic
To switch power on (off) on all (or single only) outlets need to send command on (off) to broadlink/power topic.
To switch power on (off) on outlet number N need to send command on (off) to broadlink/power/N topic.
Commands 1 / 0 are also supported
Example:
switch on 2-nd outlet: on -> broadlink/power/2

Subscription to current state

Need to set broadlink_bg1_state_interval configuration parameter to a number of seconds between periodic updates.
E.g.
broadlink_bg1_state_interval=120
means current state will be published to topics broadlink/state/[pwr/pwr1/pwr2/maxworktime/maxworktime1/maxworktime2/idcbrightness] every 2 minutes
