Temperature and humidity readings on a 2.7-inch e-ink screen: that is the Tapo T315 (UK). It reaches Apple Home, Google Home and Alexa only through a Tapo Hub's Matter Bridge, and the hub is required for its smart features. The sensor links to the hub over a sub-1 GHz band, not Wi-Fi, and runs on 2 AAA batteries that Tapo rates at up to 2 years.

“Via Matter” means you add it with that platform's Matter controller instead of a brand skill or app. “Unconfirmed” means we couldn't find an official source either way. How we verify.
