The second-generation Eve Room, a followup to the original released in 2015, uses the latest sensor technology from Sensirion to track air quality, temperature, and humidity. Eve Room has a new aluminum enclosure, an update over the original plastic enclosure.
A new e-ink display allows you to see the Eve Room measurements when a smartphone isn't available, and it now features a built-in battery that can be charged using any USB power source.
Like the original, the updated Eve Room is able to determine indoor air quality by measuring volatile organic compounds (VOC), plus it tracks the humidity and temperature of an indoor room. While the data can be read on the e-ink display, it's also available in the Eve app, Apple's dedicated Home app, and from Siri thanks to HomeKit integration.
Eve Button, Elgato's first remote-style device, is designed to allow users to activate up to three HomeKit scenes without the need for a smartphone. Eve Button fits right in with the Eve lineup, with a sleek aluminum enclosure and a single button.
A single press, a double press, and a long press are each able to trigger a different HomeKit scene. Comparatively, the Eve Button isn't offering as many physical buttons as some other options, but it is a simple, standalone device that's works with all other HomeKit products and is priced affordably at $49.95.
Eve Room will be available in March of 2018 for $99.95, while Eve Button will be available starting later this month from the Elgato website and from Apple Stores.
