Homebridge-mqtt is a Plugin for Homebridge. The design is based on MVC pattern, have a look at homebridge-mvc. Homebridge-mqtt is a dynamic Plugin that allows you to add and control accessories from a "Bridge" or "Device" with a mqtt API. Node-RED is the perfect platform to use with homebridge-mqtt.
Note-RED is a visual tool for wiring together hardware devices, APIs and online services.
If you are new to Homebridge, please first read the Homebridge documentation. If you are running on a Raspberry, you will find a tutorial in the homebridge-punt Wiki.
Install homebridge:
sudo npm install -g homebridge
Install homebridge-mqtt:
sudo npm install -g homebridge-mqtt
Add the mqtt-platform in config.json in your home directory inside .homebridge
.
{
"platform": "mqtt",
"name": "mqtt",
"url": "mqtt://127.0.0.1",
"topic_prefix": "homebridge",
"username": "foo",
"password": "bar"
}
Replace 127.0.0.1
with the ip-address of your mqtt broker.
The data (payload) is sent/received in a JSON format using following topics:
- homebridge/to/add
- homebridge/to/add/service
- homebridge/to/remove
- homebridge/to/remove/service
- homebridge/to/get
- homebridge/to/set
- homebridge/to/set/reachability
- homebridge/to/set/accessoryinformation
- homebridge/from/get
- homebridge/from/set
- homebridge/from/response
- homebridge/from/identify
Version 0.3.0 and higher supports multliple services
. To handle multiple services a new property service_name
has been introduced.
Note: To add a service to an existing accessory (created prior version 0.3.0) please first remove the accessory and add it again.
### add accessory
topic: homebridge/to/add
payload: {"name": "flex_lamp", "service_name": "light", "service": "Switch"}
response:
topic: homebridge/from/response
payload: {"ack": true, "message": "accessory 'flex_lamp' service_name 'light' is added."}
### add service
Note: an accessory with the same name
must be added before.
topic: homebridge/to/add/service
payload: {"name": "multi_sensor", "service_name": "humidity", "service": "HumiditySensor"}
response:
topic: homebridge/from/response
payload: {"ack": true, "message": "service_name 'humidity', service 'HumiditySensor' is added."}
### remove accessory
topic: homebridge/to/remove
payload: {"name": "flex_lamp"}
response:
topic: homebridge/from/response
payload: {"ack": true, "message": "accessory 'flex_lamp' is removed."}
### remove service
topic: homebridge/to/remove/service
payload: {"name": "multi_sensor", "service_name": "humidity"}
response:
topic: homebridge/from/response
payload: {"ack": true, "message": "accessory 'multi_sensor' service_name 'humidity' is removed."}
### get accessory/accessories
The purpose of this topic is to retrieve accessory configurations.
Use homebridge/from/set
to control your devices.
topic: homebridge/to/get
payload: {"name": "outdoor_temp"}
homebridge sends the accessory configuration:
topic: homebridge/from/response
payload:
{
"outdoor_temp": {
"services": {
"Temperature": "TemperatureSensor"
},
"characteristics": {
"Temperature": {
"CurrentTemperature": 13.4
}
}
}
}
topic: homebridge/to/get
payload: {"name": "*"}
homebridge sends all accessory configurations:
topic: homebridge/from/response
payload:
{
"node_switch": {
"services": {
"light": "Switch"
},
"characteristics": {
"Light": {
"On": true
}
}
},
"office_lamp": {
"services": {
"office_light": "Lightbulb"
},
"characteristics": {
"office_light": {
"On": "blank",
"Brightness": 65
}
}
},
"living_temp": {
"services": {
"living_temperature": "TemperatureSensor"
},
"characteristics": {
"living_temperature": {
"CurrentTemperature": 19.6
}
}
}
}
### set value (to homebridge)
topic: homebridge/to/set
payload: {"name": "flex_lamp", "service_name": "light", "characteristic": "On", "value": true}
### get value (from homebridge)
topic: homebridge/from/get
payload: {"name": "flex_lamp", "service_name": "light", "characteristic": "On"}
Homebridge-mqtt will return the cached value to HomeKit. Optionally you can publish the actual value using
homebridge/to/set
.
### set value (from homebridge)
topic: homebridge/from/set
payload: {"name": "flex_lamp", "service_name": "light", "characteristic": "On", "value": true}
### set reachability
topic: homebridge/to/set/reachability
payload: {"name": "flex_lamp", "reachable": true}
or
payload: {"name": "flex_lamp", "reachable": false}
### set accessory information
topic: homebridge/to/set/accessoryinformation
payload: {"name": "flex_lamp", "manufacturer": "espressif", "model": "esp8266-12", "serialnumber": "4711"}
topic: homebridge/from/identify
payload: {"name":"indoor_temp","manufacturer":"homebridge-mqtt","model":"v0.3.0","serialnumber":"2017-02-13T12:17"}
### define characterstic
The required characteristics are added with the default properties. If you need to change the default, define the characteristic-name with the properties. e.g.:
topic: homebridge/to/add
payload:
{
"name": "living_temp",
"service_name": "temperature",
"service": "TemperatureSensor",
"CurrentTemperature": {"minValue": -20, "maxValue": 60, "minStep": 1}
}
To add an optional charachteristic define the characteristic-name with "default" or with the properties. e.g.:
topic: homebridge/to/add
payload:
{
"name": "living_lamp",
"service_name": "light",
"service": "Lightbulb",
"Brightness": "default"
}
topic: homebridge/to/add
payload:
{
"name": "bathroom_blind",
"service_name": "blind",
"service": "WindowCovering",
"CurrentPosition": {"minStep": 5},
"TargetPosition": {"minStep": 5},
"CurrentHorizontalTiltAngle": {"minValue": 0, "minStep": 5},
"TargetHorizontalTiltAngle": {"minValue": 0, "minStep": 5}
}
HomeKitTypes.js describes all the predifined Services, Characteristcs, format and properties for the value
e.g.:
/**
* Service "Contact Sensor"
*/
Service.ContactSensor = function(displayName, subtype) {
Service.call(this, displayName, '00000080-0000-1000-8000-0026BB765291', subtype);
// Required Characteristics
this.addCharacteristic(Characteristic.ContactSensorState);
// Optional Characteristics
this.addOptionalCharacteristic(Characteristic.StatusActive);
this.addOptionalCharacteristic(Characteristic.StatusFault);
this.addOptionalCharacteristic(Characteristic.StatusTampered);
this.addOptionalCharacteristic(Characteristic.StatusLowBattery);
this.addOptionalCharacteristic(Characteristic.Name);
};
/**
* Characteristic "Contact Sensor State"
*/
Characteristic.ContactSensorState = function() {
Characteristic.call(this, 'Contact Sensor State', '0000006A-0000-1000-8000-0026BB765291');
this.setProps({
format: Characteristic.Formats.UINT8,
perms: [Characteristic.Perms.READ, Characteristic.Perms.NOTIFY]
});
this.value = this.getDefaultValue();
};
inherits(Characteristic.ContactSensorState, Characteristic);
Characteristic.ContactSensorState.UUID = '0000006A-0000-1000-8000-0026BB765291';
// The value property of ContactSensorState must be one of the following:
Characteristic.ContactSensorState.CONTACT_DETECTED = 0;
Characteristic.ContactSensorState.CONTACT_NOT_DETECTED = 1;
Derived from this:
service = ContactSensor
characteristic = ContactSensorState
format = UINT8
property = 0 or 1
