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

, temperature
)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 )

Update KNX Device
- Open
http://
Bridge IP /devices?id=
Device ID &value=
New Value - Insert the

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.
