Eve Door and Window review: This smart, Thread-enabled door and window sensor is only for HomeKit users

Eve Systems has been adding more and more Thread-enabled smart gadgets to its portfolio, including the Eve Aqua sprinkler controller (which we've previously reviewed) and the Eve Energy smart plug (ditto). Now comes Eve Door & Window, a HomeKit- and Thread-capable contact sensor, and it's as easy to set up and use as Eve's Aqua and Energy products. With able assistance from the Eve app, Eve Door & Window supports powerful automations and lets you take a deep dive into when, and how often, your doors and windows have been opened and closed. At $40, however, Eve Door & Window is mighty expensive for a contact sensor, and while it does support HomeKit, it doesn't work with Alexa or Google Assistant, which means only Apple users need apply. You can also configure it to trigger lighting scenes when you arrive home, or to turn down the thermostat when someone opens the window, so it's geared more toward home automation than home security; for the latter, you're on your own in terms of integrating the sensor with a third-party security system.
