Amazfit Helio Strap 2 may have just surfaced at the FCC

A new Zepp Health FCC filing has revealed an Amazfit “Smart sensor” with the model number A2671, along with a second listed variant called A2672. The filing does not name the product, but the shape, specs and timing point strongly towards the next Helio Strap or Helio Core hardware.

Zepp Health has already said that it is working on next-generation Helio hardware for the second half of 2026. This filing now gives us the first real regulatory clue that something in that line is moving through the pipeline.

The filing points to a screenless sensor

The documents describe the product as a Smart sensor rather than a smartwatch, which is the first important clue. The device uses Bluetooth Low Energy in the 2.4GHz band, with no sign of GPS, Wi-Fi, LTE, NFC or any other wireless system in the visible documents.

The external drawing is more interesting than the radio details. It shows a small rectangular module with rounded corners, a large circular sensor area on the back and two charging contacts below it. That layout pretty much matches the exact shape of the first generation Helio Strap

The model numbers are also worth noting. A2671 and A2672 do not match the current Helio Strap model references we have seen before, which suggests this is not simply the same device being copied across another document. It’s also noteworthy that two variants of the same underlying sensor module are listed. That could mean regional versions, different bundles or a standalone core and strap package.

Visible upgrades are limited for now

The interesting part is that the visible specs do not scream major hardware overhaul. The battery is listed at 230mAh, which is very close to the current Helio Core’s listed capacity. The label still shows 5 ATM water resistance and the filing focuses on basic BLE connectivity.

That does not mean upgrades are absent. FCC documents are useful for radio, battery and external design clues, but they don’t tell the full product story. Improvements to optical sensor layout, algorithms, strap design, app integration, recovery metrics or training guidance could easily sit outside the visible filing.

This is where the Helio Strap 2 story becomes more nuanced. The documents suggest continuity rather than a dramatic redesign, but they also suggest Zepp Health is preparing fresh hardware.

A stronger signal than roadmap talk

Until now, Helio Strap 2 sat mostly in roadmap territory. Zepp Health had already hinted that more Helio hardware was coming, but there was little to point to beyond that. This FCC filing changes the picture because it gives us a model number, a physical outline, wireless details and an Amazfit-branded smart sensor label.

The confidentiality request is also useful. Zepp Health asked for the external photos, internal photos, test setup photos and user manual to stay hidden until the device is marketed, or for 180 days from the FCC grant date, whichever comes first. The request itself is dated May 12th, 2026, so if the grant date sits around the same period, the withheld material would likely become public around early to mid November 2026 unless the product launches before then.

That lines up with the company’s earlier second-half 2026 comments around next-generation Helio hardware. It is not the same as a launch confirmation, but this is the kind of regulatory breadcrumb that usually appears when hardware is moving closer to release.
