Apologies for my slow responses to issues raised over the last few weeks. I do hope to catch up fully and respond soon. Thanks for all the feedback/suggestions. It's good to know that people are using this.

homebridge-mqttthing

Note that setXxx topics are published by Homebridge and should be subscribed-to by devices, and getXxx topics are published by devices to provide feedback on state to Homebridge.

Various different service types are supported by this single 'mqttthing' accessory...

Common settings

The following settings apply to all device types:

{
    "accessory": "mqttthing",
    "type": "<type of thing - supported types are described in the following sections>",
    "name": "<name of thing>",
    "url": "<url of MQTT server (optional)>",
    "username": "<username for MQTT (optional)>",
    "password": "<password for MQTT (optional)>",
    "caption": "<label (optional)>",
    "logMqtt": "true to enable logging of MQTT messages sent and received for this accessory",
    "topics":
    {
        "getName": 	        "<topic to get the name>"
    },
    "integerValue": "true to use 1|0 instead of true|false for onValue and offValue (optional)",
    "onValue": "<value representing on (optional)>",
    "offValue": "<value representing off (optional)>"
}

Homekit Boolean types like on/off use strings "true" and "false" in MQTT messages unless integerValue: true is configured, in which case they use to "1" and "0". Alternatively, specific values can be configured using onValue and offValue (in which case integerValue is ignored). Other Homekit types (integer, string, etc.) are not affected by these settings.

Supported Accessories

Contact Sensor

Contact sensor state is exposed as a Boolean. True (or 1 with integer values) maps to CONTACT_NOT_DETECTED (sensor triggered) and False (or 0) maps to CONTACT_DETECTED (not triggered). To use different MQTT values, configure onValue and offValue.

    "onValue": "<value representing on (optional)>",
    "offValue": "<value representing off (optional)>"
}

Doorbell

Doorbell ring switch state can be be SINGLE_PRESS, DOUBLE_PRESS or LONG_PRESS. By default, these events are raised when values of 1, 2 and L respectively are published to the getSwitch topic. However, these values may be overridden by specifying an alternative array in the switchValues setting.

Fan

Fan running state ('on') is true or false, or 1 or 0 if integerValue: true specified.

Fan rotation direction is 0 for clockwise or 1 for anticlockwise.

Fan rotation speed is an integer between 0 (off) and 100 (full speed).

    "onValue": "<value representing on (optional)>",
    "offValue": "<value representing off (optional)>"
}

Garage Door Opener

Garage door opener current door state can be OPEN, CLOSED, OPENING, CLOSING, STOPPED. By default, these use values of O, C, o, c and S respectively; these defaults can be changed using the doorValues setting.

Garage door opener target state can be OPEN or CLOSED. By default, values of O and C are used respectively (unless changed through doorValues).

Lock current state can be UNSECURED, SECURED, JAMMED or UNKNOWN. By default, these use values of U, S, J, ? respectively; these can be changed using the lockValues setting.

Lock target state can be UNSECURED or SECURED. By default, these use values of U and S respectively (unless changed through lockValues).

        "getStatusLowBattery":          "<topic used to provide 'low battery' status (optional)>"
    }
}

Light bulb

Light bulb can either use separate topics (for on, brightness, hue and saturation), or it can be configured to use a combined value holding comma-separated hue,sat,val or red,green,blue.

Hue is 0-360. Saturation is 0-100. Brightness is 0-100. Red, green and blue are 0-255.

If topics.setHSV is populated, a combined value is used and any individual brightness, hue and saturation topics are ignored. On/off is sent with setOn if configured, or by setting V to 0 when off.

If topics.setRGB is populated, a combined value is used in the format red,green,blue (ranging from 0-255). On/off may be sent with setOn; brightness, hue and saturation topics are ignored. If topics.setWhite is also populated, the white level is extracted and sent separately to the combined RGB value.

If topics.setRGBW is populated, a combined value is used in the format red,green,blue,white (ranging from 0-255). On/off may be set with setOn; brightness, hue and saturation topics are ignored.

    "onValue": "<value representing on (optional)>",
    "offValue": "<value representing off (optional)>"
}

Occupancy Sensor

Occupancy sensor state is exposed as a Boolean. True (or 1 with integer values) maps to OCCUPANCY_DETECTED (sensor triggered) and False (or 0) maps to OCCUPANCY_NOT_DETECTED (not triggered). To use different MQTT values, configure onValue and offValue.

    "onValue": "<value representing on (optional)>",
    "offValue": "<value representing off (optional)>"
}

Outlet

An outlet can be configured as a light or as a fan in the Home app.

    "url": "<url of MQTT server (optional)>",

    "onValue": "<value representing on (optional)>",
    "offValue": "<value representing off (optional)>"
}

Security System

Security System current state can be STAY_ARM, AWAY_ARM, NIGHT_ARM, DISARMED or ALARM_TRIGGERED. By default, these events are raised when values of SA, AA, NA, D and T respectively are published to the getCurrentState topic. However, these values may be overriden by specifying an alternative array in the currentStateValues setting.

Security System target state can be STAY_ARM, AWAY_ARM, NIGHT_ARM or DISARM. By default, these states correspond to values of SA, AA, NA and D. Homebridge expects to control the target state (causing one of these values to be published to the setTargetState topic), and to receive confirmation from the security system that the state has been achieved through a change in the current state (received through the getCurrentState topic). The values used for target state can be specified as an an array in the targetStateValues setting.

Homebridge publishes a value to the getCurrentState topic to indicate the state that the HomeKit users wishes the alarm to be in. The alarm system must echo this state back to the setCurrentState topic to confirm that it has set the alarm state appropriately. The alarm system may also publish the ALARM_TRIGGERED value (T by default) to the setCurrentState topic in order to indicate that the alarm has been triggered. If the alarm system publishes any other states to the setCurrentState topic, HomeKit will wait for it to return to the user's target state; in other words, only the HomeKit user can control the arming state of the alarm, not the alarm system itself.

    },
    "currentStateValues": "<array of 5 values corresponding to security system current states (optional)>",
    "targetStateValues": "<array of 4 values corresponding to security system target states (optional)>"
}

Smoke Sensor

Contact sensor state is exposed as a Boolean. True (or 1 with integer values) maps to SMOKE_DETECTED and False (or 0) maps to SMOKE_NOT_DETECTED. To use different MQTT values, configure onValue and offValue.

{
    "accessory": "mqttthing",
    "type": "smokeSensor",
    "name": "<name of sensor>",

    "onValue": "<value representing on (optional)>",
    "offValue": "<value representing off (optional)>"
}

StatelessProgrammableSwitch

Like a doorbell (which is based on it), the state of a stateless programmable switch can be be SINGLE_PRESS, DOUBLE_PRESS or LONG_PRESS. By default, these events are raised when values of 1, 2 and L respectively are published to the getSwitch topic. However, these values may be overridden by specifying an alternative array in the switchValues setting.

    "accessory": "mqttthing",
    "type": "statelessProgrammableSwitch",
    "name": "<name of sensor>",

    {

    },
    "switchValues": "<array of 3 switch values corresponding to single-press, double-press and long-press respectively (optional)>"
}

Switch

On/off switch.

Configuring turnOffAfter causes the switch to turn off automatically the specified number of milliseconds after it is turned on.

    "onValue": "<value representing on (optional)>",
    "offValue": "<value representing off (optional)>",
    "turnOffAfter": <milliseconds after which to turn off automatically>
}
