Joe TriesDoor and window sensors
A contact sensor is two small pieces, one stuck to the door and one to the frame, that report whether it is open or closed. They are cheap and unglamorous and they are the trigger behind most of the automations people actually keep. Almost none are Wi-Fi, so you are picking one to match the hub you already own.

What decides compatibility
- Almost all need a hub. If you have no hub yet, that is the real purchase.
- Gap tolerance decides the install. Sensor and magnet have to sit within a few millimeters, which is a problem on uneven or recessed frames.
- Battery type matters for cost over time. Coin cells are cheap, and a house full of them is a recurring chore.
- Size matters on a window sash. A bulky sensor can block the window from closing.
How these connect to your system
A works-with badge does not say how the device gets there, and the path changes what you get. Direct means the maker built the integration and the device's own features tend to come with it. Via Matter means the standard controls work and anything unusual about the device may not carry over. Via a hub means you need a second box, usually the maker's own, before it works at all.
