SwitchBot MQTT client
![Compatible Python Versions](https://img.shields.io/pypi/pyversions/switchbot-mqtt.svg)
MQTT client controlling SwitchBot button automators
and curtain motors
Compatible with Home Assistant's
MQTT Switch
and MQTT Cover platform.
Setup
$ pip3 install --user --upgrade switchbot-mqtt
Usage
$ switchbot-mqtt --mqtt-host HOSTNAME_OR_IP_ADDRESS --mqtt-enable-tls
$ switchbot-mqtt --mqtt-host HOSTNAME_OR_IP_ADDRESS --mqtt-disable-tls
Use sudo hcitool lescan
or select device settings > 3 dots on top right in
SwitchBot app
to determine your SwitchBot's mac address.
Button Automator
Send ON
or OFF
to topic homeassistant/switch/switchbot/aa:bb:cc:dd:ee:ff/set
.
$ mosquitto_pub -h MQTT_BROKER -t homeassistant/switch/switchbot/aa:bb:cc:dd:ee:ff/set -m ON
The command-line option --fetch-device-info
enables battery level reports on topic
homeassistant/switch/switchbot/MAC_ADDRESS/battery-percentage
after every command.
The report may be requested manually by sending a MQTT message to the topic
homeassistant/switch/switchbot/MAC_ADDRESS/request-device-info
(requires --fetch-device-info
)
Curtain Motor
Send OPEN
, CLOSE
, or STOP
to topic homeassistant/cover/switchbot-curtain/aa:bb:cc:dd:ee:ff/set
:
$ mosquitto_pub -h MQTT_BROKER -t homeassistant/cover/switchbot-curtain/aa:bb:cc:dd:ee:ff/set -m CLOSE
Or a position in percent (0 fully closed, 100 fully opened) to topic
homeassistant/cover/switchbot-curtain/aa:bb:cc:dd:ee:ff/position/set-percent
:
$ mosquitto_pub -h MQTT_BROKER -t homeassistant/cover/switchbot-curtain/aa:bb:cc:dd:ee:ff/position/set-percent -m 42
The command-line option --fetch-device-info
enables position reports on topic
homeassistant/cover/switchbot-curtain/MAC_ADDRESS/position
after STOP
commands
and battery level reports on topic homeassistant/cover/switchbot-curtain/MAC_ADDRESS/battery-percentage
after every command.
These reports may be requested manually by sending a MQTT message to the topic
homeassistant/cover/switchbot-curtain/MAC_ADDRESS/request-device-info
(requires --fetch-device-info
)
Device Passwords
In case some of your Switchbot devices are password-protected,
create a JSON file mapping MAC addresses to passwords
and provide its path via the --device-password-file
option:
{
"11:22:33:44:55:66": "password",
"aa:bb:cc:dd:ee:ff": "secret",
"00:00:00:0f:f1:ce": "random string"
}
$ switchbot-mqtt --device-password-file /some/where/switchbot-passwords.json …
MQTT Authentication
switchbot-mqtt --mqtt-username me --mqtt-password secret …
switchbot-mqtt --mqtt-username me --mqtt-password-file /var/lib/secrets/mqtt/password …
⚠️ --mqtt-password
leaks the password to other users on the same machine,
if /proc
is mounted with hidepid=0
(default).
MQTT Topic
By default, switchbot-mqtt
prepends homeassistant/
to all MQTT topics.
This common prefix can be changed via --mqtt-topic-prefix
:
switchbot-mqtt --mqtt-topic-prefix living-room/ …
switchbot-mqtt --mqtt-topic-prefix '' …
Service Status Report
After connecting to the MQTT broker, switchbot-mqtt
will report online
on topic homeassistant/switchbot-mqtt/status
.
When disconnecting (graceful shutdown or unexpected loss of connection), offline
will be reported on the same topic.
Home Assistant 🏡
Rationale
Why not use the official SwitchBot integration?
I prefer not to share the host's network stack with home assistant
(more complicated network setup
and additional netfilter rules required for isolation).
Sadly, docker run --network host
even requires --userns host
:
docker: Error response from daemon: cannot share the host's network namespace when user namespaces are enabled.
The docker image built from this repository works around this limitation
by explicitly running as an unprivileged user.
The official home assistant image
runs as root
.
This imposes an unnecessary security risk, especially when disabling user namespace remapping
(--userns host
).
See https://github.com/fphammerle/docker-home-assistant for an alternative.
