-Doorman is an ESP32 or ESP8266 based mqtt bridge for TCS door control systems (<https://www.tcsag.de/>).
+Doorman is an ESP32 or ESP8266 based mqtt bridge to connect your [TCS](https://www.tcsag.de/) or [Koch](https://www.kochag.ch/) Intercom to any home automation system.
 
 ![doorman opener](doc/doorman.gif)
 
 ## Main Features
 
-* Mqtt integration for all messages read from the bus and for writing messages to the bus
+* Support for TCS bus based intercom systems from TCS AG (Germany) or Koch AG (Switzerland)
+* Automatic Homeassistant discovery via MQTT
+* MQTT integration for all messages read from the bus and for writing messages to the bus
 * Button push pattern detection - you can define a pattern and assign a code that is written to the bus if the pattern is detected (Example: automatically open the door if the doorbell is pressed x times in a certain way). A successfully detected pattern is also published via mqtt.
 * Party mode (When this is enabled, the door opener automatically opens if the door bell is pressed)

+AzonInc created a PCB with the doorman circuits and 3D printable housing. The project supports integration via ESPhome.
