Does the Dexcom Stelo alert followers on signal loss?

What Dexcom Stelo’s own apps (Stelo app) do, from the maker’s documents.

Partly

The Stelo app shows a Sensor reconnecting message after a few minutes without readings. The maker documents no adjustable signal-loss alert and no follower app. (Stelo (Dexcom))

Stelo is sold over the counter in the US only. Dexcom says your primary residence and your Stelo account must be in the US.
