Onvis T20 smart plugs quietly bring serious Matter and energy‑tracking upgrades

Smart‑home vendor Onvis has quietly become the talk of home‑automation forums after unveiling its new T20 series at the end of July 2026, with products scheduled to roll out from late August. The lineup covers an in‑wall outlet, an indoor smart plug and a weather‑resistant dual outdoor plug, all built around Matter over Thread – the upcoming cross‑vendor smart‑home standard combined with a low‑power mesh network protocol.

What really has enthusiasts excited is native energy metering. Paired with Apple’s iOS 27 beta, the T20 devices report real‑time power usage directly into the Apple Home app, making it easy to see which appliances are driving your electricity bill. That’s particularly useful for always‑on gear like heaters, dehumidifiers or network equipment. Outside Japan, there’s a clear trend toward upgrading “boring” infrastructure such as outlets and power strips so that future smart‑home features can be layered on top. The T20 series is being cited as a reference design for how Matter‑first accessories should work: simple form factors, Thread connectivity by default, and energy data as a standard feature rather than an expensive add‑on.
