Does anyone know if it's possible to see blood sugar readings on the screen of a Tesla vehicle? Is this doable?

After our five-year-old was diagnosed with Type 1 Diabetes, we quickly realized how impractical it can be for a young child to keep a phone nearby all day and night just to maintain CGM sharing.

That led me to start building SweetPea, an experimental Wear OS app that connects directly to a Dexcom G7, captures the current glucose reading, and uploads it to Gluroo through a Nightscout-compatible connection.

Tonight we reached a big milestone: the collector now continues running while the watch screen is asleep and can upload over either Wi-Fi or cellular. Wi-Fi is preferred when available to help preserve battery, but cellular allows the watch to keep sharing readings when it is away from home and without a phone nearby.

We also adjusted the Bluetooth timing so the watch wakes and scans close to the next expected five-minute Dexcom cycle instead of scanning continuously. In our latest testing, it has been capturing consecutive readings and successfully delivering them to Gluroo.

The video is a live demonstration of the watch receiving a G7 reading and confirming that it was sent to Gluroo.

This is still an early experimental prototype. It is not an approved medical device, is not being relied upon for dosing or emergency alerts, and still needs much more reliability, battery, security, and long-duration testing. But it is exciting to finally see the full phone-independent path working:

Dexcom G7 → Wear OS watch → Wi-Fi/cellular → Gluroo → caregiver phone

Multi-Billion dollar company and they refuse to have any Disaster Recovery. Or redundantcy. Why are the G7 so expensive?

Is this gonna fail? Sucks to be diabetic I swear

Does anyone know anything about selling their G6 supplies? Is it legal? Is there a legitimate place that buys them? We are switching to the G7 and I have a ton of G6 sensors left over that I am not sure what to do with...
Edit: I am not trying to sell them on reddit. sorry for the confusion, I keep seeing these ads for companies that want to buy them. That's why I'm inquiring.

I usually have my Dexcom G6 data on my Apple Watch (not direct to watch, but from my phone), but closed my Dexcom app, reopened, and now it doesn’t even show up as something that I can access on my watch. Any tips?

Today, while visiting Berlin, I had to change my sensor. My Dexcom G6 expired and as it was the last of my supply, I had to switch back to the G7. This happened in the middle of heavy rain. So I went inside a nearby church for cover. I ended up changing my Dexcom as intricate statues of Jesus and Mary and beautiful architecture looked down on me, and a priest had even just started a sermon.

What’s the strangest or most unconventional place you’ve changed your sensor?

I’ve used the G6 for years with no real problems. But, of course I had to switch to the G7 and applied my first one a couple weeks ago. It started itching soon after installing it, and got worse. Finally I took it off after about 8 days. I was left with a pretty severe rash that looks like a bad sunburn. I’m debating whether to try another since I have 8 left.

I’ve read some posts with ideas, but they seem a bit wild, and not clear if they will work

Should I switch to another brand? Any other ideas? I may just go without, my A1C has been very good (< 6.0). I just liked wearing it because it would occasionally alert when I had a low reading

My Clarity account seems to be stuck in February 2025. This shows on both the phone app and the website. I have tried manually updating the date range but it just goes back to February 2025.

It doesn't appear that Clarity has been discontinued. Am I missing something?

Does your former site hurt? We remove it when indicated, then put tje new one elsewhere, and if anything like shirt sleeve or squeezing my arm against my body for whatever reason, it hurts like he!!. It feels like a pimple or something for several days. What is up with that? G6 never had an issue. Thanks

Sometimes adhesive just doesnt work on me. Don't know why. Maybe the lot has some sort of issue? The last two times I tried putting on my Dexcom it was like a half hour after taking a shower, but my skin wasn't wet anymore by the time I was putting it on, so idk

Not even gonna lie I was running late for work yesterday & it wasn't sticking after I put it on so I straight up superglued it on 💀 This has been happening to me a lot lately so I'd had enough
