Installation

1. Install homebridge using: sudo npm install -g homebridge
2. Install this plugin using: sudo npm install -g homebridge-syntex-knx
3. Update your config.json file. See snippet below.
4. Restart the Homebridge Service with: sudo systemctl restart homebridge; sudo journalctl -fau homebridge

Example Config

Info: If the baseDirectory for the storage can't be created you have to do it by yourself and give it full write permissions!

• sudo mkdir -p /var/homebridge/SynTex/ ( create the directory )
• sudo chmod -R 777 /var/homebridge/SynTex/ ( permissions for many processes )
• sudo chown -R homebridge /var/homebridge/SynTex/ ( permissions only for homebridge )

Required Parameters

• platform is always SynTexKNX
• baseDirectory The path where cache data is stored.
• ip The IP address of your KNX gateway.
• accessories For the accessory config.

Optional Parameters

• port To control your accessory over HTTP calls.
• language You can use your country initials if you want to change it ( Currently supported: us, en, de )
• disablePreload Disable reading device states after reboot ( prevents the bus from overflow )

Log Parameters

• Disable certain log level: error, warn, info, read, update, success and debug ( for example debug: false )

Accessory Config

• Every accessory needs these parameters: id, name and services ( required )
• id has to be either a physical group address or another random unique text ( no duplicates! )
• name could be anything.
• services The services of your accessory.
  
  
  • name could be anything.
  • type Define the service type ( blind, contact, dimmer, fan, humidity, leak, led, light, motion, occupancy, outlet, rain, relais, rgb, smoke, switch, temperature, thermostat )
  • address can include your status and probably control group address from your knx system.
  • You can customize group address datapoints by adding datapoint ( KNX datapoint types )
  • For Boolean and Percentage Devices you can add inverted ( inverts the state from false -> true / 0 -> 100 )
  • For Window Coverings you can add delay for up and down ( to calibrate the time it takes to open / close the covering )

SynTex UI

Control and set up your devices by installing homebridge-syntex
This plugin is made for plugin management, automation system and device control.

Check out the GitHub page for more information:
https://github.com/SynTexDZN/homebridge-syntex

Update KNX Device

1. Open http:// Bridge IP /devices?id= Device ID &value= New Value
2. Insert the Bridge IP and Device ID
3. For the New Value you can type this pattern:

• For boolean devices: true / false ( dimmer, fan, led, outlet, rgb, switch )
• For numeric devices: 10 / 12.4 ( blind, thermostat )
• For dimmable lights add &brightness= New Brightness ( has to be a number )
• For colored lights add &hue= New Hue ( has to be a number )
• For colored lights add &saturation= New Saturation ( has to be a number )
• For thermostats add &target= New Target Temperature ( has to be a number )
• For thermostats add &state= New Current Heating Cooling State ( has to be a number )
• For thermostats add &mode= New Target Heating Cooling State ( has to be a number )
• For fans add &direction= New Rotation Direction ( has to be a number )
• For fans add &speed= New Rotation Speed ( has to be a number )
• For accessories with multiple service types add &type= SERVICETYPE
• For accessories with multiple services with more than one of the same service type add &counter= SERVICENUMBER
  ( First of that type = 0, second = 1 .. )

Example: http://homebridge.local:1714/devices?id=ABCDEF1234567890&type=dimmer&counter=0&value=true&brightness=100
( Updates the value and brightness of ABCDEF1234567890 to turned on, 100% brightness for example )

Read KNX Device

1. Open http:// Bridge IP /devices?id= Device ID
2. Insert the Bridge IP and Device ID

• For accessories with multiple service types add &type= SERVICETYPE
• For accessories with multiple services with more than one of the same service type add &counter= SERVICENUMBER
  ( First of that type = 0, second = 1 .. )

Example: http://homebridge.local:1714/devices?id=ABCDEF1234567890
( Reads the state of ABCDEF1234567890 for example )

Remove KNX Device

1. Open http:// Bridge IP /devices?id= Device ID &remove=CONFIRM
2. Insert the Bridge IP and Device ID

• To remove a specific service add &type= SERVICETYPE
• To remove a specific service from an accessory with more than one of the same service type add &counter= SERVICENUMBER
  ( First of that type = 0, second = 1 .. )

Example: http://homebridge.local:1714/devices?id=ABCDEF1234567890&remove=CONFIRM
( Removes ABCDEF1234567890 from the Config and Home App )

Automation

To enable the automation module you have to create a file named automation.json in your baseDirectory >> automation or install the homebridge-syntex plugin to create them via UI ( only between SynTex plugins )

Example: For manual configuration update your automation.json file. See snippet below.

        {
            "id": 0,
