Elgato has updated its Eve Room sensor and revealed the new Eve Button controller for managing HomeKit scenes and devices. The second-generation Eve Room ($100) still features the previous model’s monitoring of air quality, temperature and humidity, but the new version has its own e-ink display rather than just relying on the dedicated app to display information.

Eve Room also now includes its own built-in battery that can be charged via USB instead of the 2015 model’s reliance on AA batteries — the first time we’ve seen Elgato include a rechargeable battery in one of its Eve products. The new Eve Room borrows its black and aluminum aesthetic from the award-winning Eve Degree that we reviewed last year, making for a much sleeker look to go along with the $20 price increase over the older model when the new device debuts in March.
Rounding out its new offering, Elgato has also released Eve Button ($50), a simple Bluetooth controller for HomeKit scenes and devices for those who want to use a dedicated remote rather than their iPhone.
Featuring the same black and aluminum design as the Eve Room, the Eve Button can activate three different HomeKit scenes with a single, double or long press. Perfect for places where multiple users need quick control of HomeKit scenes, the Eve Button can be installed within any HomeKit setup without a bridge and can be installed within a few minutes from Eve’s app or Apple’s Home app.
