DIY universal taster interface for the KNX bus.
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.
While commercial alternatives exists, for example the MDT Universal Interface or the ABB Universal Interface, 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.
You can find the following in this repository:
- 3D prints - Printable parts, such as an enclosure
- Firmware - Firmware files
- PCB designs - KiCad designs for the main PCB and extensions
You can buy the boards from Aisler.net, and help me to support the development.
