What is a Matter Binding?

In addition to control via a smart home hub, the Matter standard also offers another method: automation through so-called bindings. End devices (endpoints) in a Matter installation communicate directly with each other. They exchange information – for example, by radio – and do not need a control center as an intermediary. Typical examples of this method are:

  • Light switches/dimmers that control one lamp or a group of lamps.
  • Temperature sensors that control one or more heating regulators.

The second category includes the upcoming Eve Thermo Control, which manufacturer Eve Systems presented at IFA 2023 in Berlin. Like the Eve Thermo radiator regulator, it works with the Thread wireless protocol. The manufacturer’s app establishes a binding between both products so that the regulator subscribes to the sensor data and receives the current room temperature from it periodically.

Matter‘s binding concept applies across all manufacturers. This means that products from different brands can also be combined in this way. However, no manufacturers have made use of it yet. Eve will be among the first when the Thermo Control is launched on the market in November as planned. To what extent large Matter ecosystems will then integrate the function into their apps remains to be seen. Since it works independently of hubs such as the Apple HomePod, Amazon Echo or Google’s Nest Hub, users would become more independent of the platforms.
