About Matter Survey

Matter Survey is a community-driven database that catalogs the real-world capabilities of Matter-compatible smart home devices. We collect anonymous data from users' actual devices to help you understand what works with what.

What is Matter?

Matter is a new smart home standard that lets devices from different brands work together. Before Matter, if you bought a Philips light bulb, it might only work with the Philips app. A Samsung sensor might only work with SmartThings. Getting everything to talk to each other was a nightmare.

Matter fixes this. It's a common language that devices can speak, backed by major tech companies:

Why does this site exist?

Matter promises compatibility, but the reality is more nuanced:

• Different devices have different features. A basic bulb just turns on/off. A fancy one supports colors, brightness, and scenes.
• Not all features are exposed. Some devices have capabilities they don't advertise over Matter.
• Binding support varies. "Binding" lets devices talk directly to each other (like a switch controlling a bulb without going through a hub). Not all devices support this.
• Firmware updates change things. A device might gain or lose features over time.

Matter Survey collects real data from real devices to show you exactly what each device can do - not just what the marketing says.

What data do we collect?

We collect only technical device information:

• Device identifiers (vendor ID, product ID)
• Supported features (clusters, device types)
• Firmware versions
• Connection type (Thread, WiFi, Ethernet)

We do NOT collect: your name, location, network info, usage patterns, or anything that could identify you personally. Your privacy is respected.

How is data collected?

Data is contributed by users of the Matter Binding Helper Home Assistant add-on. When users opt in, their device capabilities are anonymously submitted to this database.
