The Connectivity Standards Alliance certification database has unveiled another previously unannounced Matter-compatible smart home device this week—an all-new 5th-generation Eve Thermo. Similar to other smart radiator valves, the upcoming Eve Thermo should provide convenient remote controls and temperature-based automation capabilities for room heating systems.
Eve Thermo 5th-generation: new looks, same connectivity
Although little is known at the moment, according to the CSA listing, the new Eve Thermo's model number is 20ECD1701. The upcoming radiator valve earned its Matter certification (version 1.4.1) with firmware version 3.6.5 just a few days ago on 11/21/25.
We can also see that the 5th-generation Eve Thermo sports a redesigned tapered chassis that gives it a much sleeker look over the previous model. While slimmer, the new Eve Thermo still features on-device controls for temperature adjustments and features a large, easy-to-read digital display.
Also redesigned is the screw-on fitting located at the bottom of the Eve Thermo that connects to a radiator. The new fitting appears to have a matte finish versus a polished chrome look previously, but we cannot determine if it is metal or plastic, or if it will offer greater durability at this time.
When it comes to connectivity, the Eve Thermo—like other devices from the company—lists Bluetooth and Thread as its transport interface. With Thread, it should integrate seamlessly with existing Border Routers and Matter right out of the box with a scan of the QR pairing code, and it will presumably offer high levels of reliability, long battery life, and speedy response times.
Eve Thermo 5th-generation: coming soon?
With a little further digging, we were able to track down an EU Declaration of Conformity for the upcoming device, which indicates that it has been in the works since at least July. And with CES 2026 on the horizon, we expect to see an official announcement sooner rather than later.
Here's to hoping that it makes it to store shelves in time for the coming Winter season.
