User Guide – Snips

Snips provides Private-By-Design, Decentralised Voice Assistant Technology and Solutions.

The voice recognition runs directly on the realKNX device, meaning no one will ever hear your voice but you. This page some background and how you can use the realKNX Air Snips voice control system.

Introduction: How to use Snips voice control with realKNX Air

Example, say Hey Snips, turn on the lights! or Hey Snips, what is the temperature of the Bedroom?

  • ‘Hey Snips’ is the Hotword (or wakeword).
  • ‘turn on the lights!’ is a Command.
  • and ‘what is the temperature of the Bedroom?’ is a Query.

For best result, use short delay (~1s) between the Hotword and Command/Query


The command ‘turn on the lights!’ will try to turn on the lights in the room where the speaker microphone (a.k.a satellite). For a better experience, each satellite should be attributed to one room. If a satellite is attributed to the Bedroom and the command ‘turn on the lights!’ is given the lights in the Bedroom will be lit.

If you want to turn on the Kitchen lights, from the Living Room, you need to add the room to the command. Saying ‘turn on the Kitchen lights!’ will turn on the Kitchen lights from any satellite.

Natural Language Understanding

There are thousands of different possibilities to ask realKNX Air to control your KNX installation. That’s possible thanks to Natural Language Understanding. The NLU is based on deep machine learning technology and thousands of training examples. Together with clever handling of the commands you’re not limited to simple ‘turn on/off’-commands but you can use natural language.

Here are some examples of alternatives to control your installation:
