So I’ve been running a Libre 3 Plus and Dexcom Stelo on myself for several days. I have Shuggah connected to the Stelo and sending the data to Nightscout while there is a separate “sidecar” service handling the Libre data going into Nightscout. Basically, I can follow the data all in one place within Nightscout even if it’s not really designed for that.
The Stelo is consistently reading higher than the Libre. The range at which it tends to be higher can be just a few mg/dL to as high as 40 mg/dL. Dexcom does a bit more smoothing so rate of change can be slightly slower.
More interesting: who is more accurate? The last 2 blood checks have shown the Libre to be within a few mg/dL.
Neither of these can be calibrated.
I have to switch to G7 (what the Stelo is based on) when I start on a pump, which I believe does allow for calibration.
Disclaimer: Stelo is not meant to be used by people using insulin. I am basing my dosing decisions on my Libre 3 Plus.
Super interesting data and observations! Will be interesting to see how they behave towards the end of their 15 days, as Dexcom’s G7 has struggled to stay consistent for its 10 day life, based on users of that system.
