 # KNX Universal Taster
-DIY universal taster for the KNX bus.
+DIY universal taster interface for the KNX bus.
+
+## Introduction
+This repository contains my designs for creating a custom KNX universal taster
+interface (or actor). This is board that can be used for several purposes, but
+its main purpose is to convert pulse-based wall switches into KNX-enabled
+switches. The boards are designed to be small and should fit wall boxes with a
+depth of 50 mm.

+
+I currently have 25 boards installed in my house. As of writing (January 2021),
+they have been running for more than two years.
+
+## Features
+While commercial alternatives exists, for example the [MDT Universal Interface](https://www.mdt.de/EN_Universal_Interface.html)
+or the [ABB Universal Interface](https://new.abb.com/products/GHQ6310070R0111/us-u4-2-universal-interface-4-fold-fm),
+I challenged myself to create a version that has more capabilities:
+
+* Smaller.
+* Programmable button options, e.g. multiple presses, long(er) presses.
+* Support for (environmental) sensors.
+* Universal use: data loggers, protocol gateways (Modbus, DSMR).
+* Remote configuration via ETS or other software.
 
 ## Contents
-This repository contains the following boards.
+You can find the following in this repository:
 
-* [Taster](Taster/README.md) - The main board.
-* [Environmental-Sensors](Modules/Environmental-Sensors/README.md) - Environmental sensor board that fits inside a Busch-Jaeger switch.
-* [DSMR-Connector](Modules/DSMR-Connector/README.md) - Opto-isolated converter to the P1 port of Dutch Smart Energy Meter (DSMR 5.0).
-* [RS485-Connector](Modules/RS485-Connector/README.md) - Opto-isolated RS485 converter.
-* [Interface-Tester](Interface-Tester/README.md) - Testing board to evaluate the taster.
+* [PCB designs](pcb) - KiCad designs for the main PCB and extensions
 
-You can buy the boards from [Aisler.net](https://aisler.net/p/GGKCSYBF), and help me to support the development.
