Maybe it is possible the google engineer didn't understand how open source licenses work, or didn't care since maybe it was supposed to be an internal project first that eventually ended up open sourced?

I guess $30 for what is effectively a glorified chime for your door is a bit much, but considering the time it probably took to put together this (kind of over-engineered) and the (presumably) monthly cost of the VPS, it makes more sense.

Also, I feel like something like MQTT or another message broker could simplify this significantly, making the whole VPS /state endpoint unnecessary, without exposing your home mini pc to the internet, since the mini pc would connect to the MQTT (I think HA actually has a built in mqtt integration? although you'll still need to make something to process the message once the MQTT gets it) and the SmartThings API would also (assuming the processing after the SmartThings API is hit is customizable in some form)

CGMs use the interstitial fluid in (usually, although people also use other spots) inside side of the upper arm to measure blood sugar. As long as they are placed in the right spot (i.e. in a fattier area instead of directly on top of muscle, hence why it is on the inside side of the upper arm and not the outside) and the sensor doesn't fail, they will measure blood sugar fairly accurately for 10-15 days depending on the CGM model (disclaimer: They do tend to run approximately 15 minutes behind the number that an actual finger poke would show you).

Nightscout is an awesome tool because it can be self-hosted so that you keep full control over your health data, but since it is a web application, you can still easily share it with other people too, like family or your endocrinologist.

On android, you can use the xdrip+ application to pair with most types of CGMs to completely keep your data out of the cloud, or you can also pair it with the API from Abbott or Dexcom (depending on the CGM model) to pull data from their 'share/link' applications, if you opt to pair with/use their official apps

I personally use Dexcom G7 15 day sensors (because it is what my insurance covers) and use xdrip+ to upload the data to a nightscout instance hosted in my homelab

Seems that they didn't make/train a new novel model, they did a mix of two existing models and then gave it an instruction to say it was 'Rio, trained by Rio AI Labs'

I've always been told (and this has been true over the 4 or 5 times I've been hospitalized in my life) that having someone there for you, to support you and also to serve as your 'patient advocate' (so helping making sure all of the questions are asked of the doctors and stuff like that) has a definite positive effect on medical outcomes. In my cases, it was my family filling this role.
