A simple Z-Way to MQTT bridge in GO.
The service sends MQTT message for all handled classes to the a MQTT broker.
Classes can be handled either read only (ro), typicaly for sensors, or read only (ro) ,typicaly for switches.
There is a base subject for MQTT (root topic; per default "razberry").
The nodename will be read form the Z-Way node.
In principle nodes will be split between actuators and sensors and between binray and analogic ones.
The instance is always used. (i)
Currently the bridge is limited to certain ZWave classes (see bellow).
Usage of zwaymqtt:
-h string
mqtt topic root or ZWAY_HOME environment variable (default "razberry")-m string
MQTT server or MQTT_SERVER environment variable (default "localhost:1883")-mp string
MQTT password or MQTT_PASSWORD environment variable-mu string
MQTT username or MQTT_USERNAME environment variable-p string
Z-Way passsword or ZWAY_PASSWORD environment variable-profile string
Profile execution (cpu/mem/all)-proto string
MQTT protocol tcp/ws/tls MQTT protocol tcp/ws/tls or MQTT_PROTOCOL environment variable (default "tcp")-r int
Z-Way refresh rate in seconds or ZWAY_REFRESH environment variable (default 30)-s string
Z-Way server name or ZWAY_SERVER environment variable (default "localhost:8083")-u string
Z-Way username or ZWAY_USERNAME environment variable (default "admin")-v Show debug messages
notice that main parameters are mapped by an environment variable
All builds are pushed to docker:
Default tags includes:
- branch (i.e.: master) for latest commit in the branch
- latest for latest release
Please use environment variables to configure:
- MQTT topic root = ZWAY_HOME
- MQTT server = MQTT_SERVER
- MQTT password = MQTT_PASSWORD
- MQTT username = MQTT_USERNAME
- MQTT protocol = MQTT_PROTOCOL
- Z-Way server name = ZWAY_SERVER
- Z-Way username = ZWAY_USERNAME
- Z-Way password = ZWAY_PASSWORD
- Z-Way refresh rate = ZWAY_REFRESH
- Show debug messagees = ZWAYMQTT_DEBUG (set to 'true')
Setup an environment file with the required parametes
'/etc/default/zwaymqtt'
ZWAY_HOME = zway
ZWAY_SERVER = localhost
ZWAY_USERNAME = admin
ZWAY_PASSWORD = admin
ZWAY_REFRESH = 3
MQTT_PROTOCOL = tls
MQTT_SERVER = localhost
MQTT_USERNAME = mqtt
MQTT_PASSWORD = mqtt
Run the docker image
docker run --env-file:/ext/default/zwaymqtt cblomart/zwaymqtt
On your pi:
$ wget https://github.com/cblomart/zwaymqtt/releases/download/0.1/zwaymqtt-linux-arm5.tgz
sudo tar -zxvf ./zwaymqtt.tgz -C /
sudo vi /etc/default/zwaymqtt
sudo systemctl enable zwaymqtt
sudo systemctl start zwaymqtt
I install the software at home with the RaZberry.
To do this:
-
be sure to have GO and ability to cross compile. (If you do not, you can alway run it with go on a pc)
-
compile for an arm running linux (raspberry) on a pc:
$ GOOS=linux GOARCH=arm GOARM=5 go get github.com/cblomart/zwaymqtt
- copy the necessary files to your Pi:
$ scp $GOPATH/src/github.com/cblomart/zwaymqtt/etc/systemd/system/zwaymqtt.server pi@raspberry.local:/tmp/
$ scp $GOPATH/src/github.com/cblomart/zwaymqtt/etc/default/zwaymqtt pi@raspberry.local:/tmp/
$ scp $GOPATH/bin/linux_arm/zwaymqtt pi@raspberry.local:/tmp/zwaymqtt.bin
- on your pi, place the files at the right places:
$ sudo cp /tmp/zwaymqtt.server /etc/systemd/system/
$ sudo cp /tmp/zwaymqtt /etc/default/
$ sudo cp /tmp/zwaymqtt.bin /usr/local/bin/zwaymqtt
-
on your pi, edit the /etc/default/zwaymqtt to match your preferences
-
on your pi, enable and start the service:
$ sudo systemctl enable zwaymqtt
$ sudo systemctl start zwaymqtt
Encompassed classes:
- COMMAND_CLASS_BATTERY (ro)
The events on this class will be mapped to the "<root_topic>/sensors/analogic/<nodename>/<i>/battery" topic.
i.e.: razberry/sensors/binary/detector_door_basement/0/general_purpose
Encompassed classes:
- COMMAND_CLASS_SWITCH_BINARY (rw)
The events on this class will be mapped to the "<root_topic>/actuators/binary/<nodename>/<i>/switch" topic.
i.e.: razberry/actuators/binary/binary_switch_living/1/switch
Encompassed classes:
- COMMAND_CLASS_SWITCH_MULTILEVEL (rw)
The events on this class will be mapped to the "<root_topic>/actuators/analogic/<nodename>/<i>/dimmer" topic.
TODO: put an example (i have no multilevel switch to test)
Encompassed classes:
- COMMAND_CLASS_SENSOR_BINARY (ro)
The utility will be determined by the sensor type described on the node. If it is a generic sensor... "generic" will be used.
The events on this class will be mapped to the "<root_topic>/sensors/binary/<nodename>/<i>/<utility>" topic.
i.e.: razberry/sensors/binary/detector_entry/0/motion
Encompassed classes:
- COMMAND_CLASS_SENSOR_MULTILEVEL (ro)
- COMMAND_CLASS_METER (ro)
The utility is still used but the scale type has been added.
The events on this class will be mapped to the "<root_topic>/sensors/binary/<nodename>/<i>/<utility>/<scale>" topic.
i.e.: razberry/sensors/analogic/detector_entry/0/temperature/c
Encompassed classes:
- COMMAND_CLASS_THERMOSTAT_SET_POINT (rw)
Todo: more desctiption ;-)
