Does the SIBIONICS GS1 alert followers on signal loss?
What SIBIONICS GS1’s own apps (SIBIONICS GS1 app, SiBionics Companion) do, from the maker’s documents.
Yes
The SIBIONICS app has a Signal Loss alarm. You set how long the sensor can be silent before it alerts; the guide gives no default time and does not say whether followers get this alarm. (SIBIONICS user guide, p. 36)
The GS1 is not FDA-cleared and is not sold in the US; these answers come from SIBIONICS's EU/UK English user guide, its sibionicscgm.com pages and the UK App Store.
