Connect Modbus, KNX, Zigbee, ZWave and MQTT with Matter


At StreamUnlimited, we have our StreamSDK - a flexible, feature rich and modular stack dominated by streaming and premium audio functionality. It makes sense to offer the same thing for IoT - with multiple interacting protocols, local rule engines and a modular approach. We call this StreamThings, and it finally provides a way to make IoT interoperability easy, and to build really Smart Integrations.

StreamThings provides API integrations and dramatically reduces product development complexity. The powerful framework for both offline and cloud connected system control, combined with multi-protocol interoperability - a key issue in IoT ecosystem management - enables seamless Smart Integration for a wide variety of products in various segments.

The combination of StreamSDK, and StreamThings, integrated in your product, prepares your Brand for the Smart World - a future where products must interact on multiple levels, with various control methods, in environments ranging from the home and office to the factory floor. There is no longer room for "simple soundbar development", and as a member of the CSA, StreamUnlimited brings reliable, interoperable connectivity to smart environments using Matter.

StreamUnlimited's unparalleled experience in audio has benefits which support numerous use cases in smart product integration - Bluetooth, Voice Assistants, Acoustic Echo Cancellation, WiFi to name a few examples.

You can select our fully customisable, locally hosted voice assistant and use StreamThings to scale from single devices to a whole system (multiple device types working together), with sensors in a large local environment synching with cloud infrastructure and implementing actions. StreamThings can power multiple devices operating with different functionality (eg sensors, audio, actions]

StreamThings is a low footprint, powerful application software with a modular structure that connects to any IoT protocol. Together with the StreamCloud it provides a way to enable high security / privacy applications.
