Statically, that’s not true, and is bordering on decades-old fear mongering about EVs.

In modern EVs, the battery will likely outlast the car body it is sitting installed in, or at least match the expected lifespan of the vehicle. There are a few EVs on the road right now with battery packs that have been driven many hundreds of thousands of miles.

The upfront cost of EVs is still a problem, but most people won’t need to spend thousands on a new or refurbished battery pack after a few years.

Here’s a well-made (and broadly pessimistic) source if you’re interested: https://www.nature.com/articles/s41560-024-01698-1

This is what I installed last year after I got an open box model online for a significant discount. It was easy to set up and works great with HA.

Ok great! Best of luck and have fun.

I can’t really give you a step-by-step guide, but here’s the gist of how I did it: I have a dexcom CGM, and use the dexcom share functionality in the app to sync the CGM data to a Home Assistant plug in. From there, the blood glucose data is treated like any other sensor value in Home Assistant, so the sky is the limit.

How you could implement this for your mom would depend on what brand of CGM she can get, and the level of tech aversion or savvy she is. xDrip and Nightscout are excellent projects which would also help you make something that uses or displays CGM data, if you didn’t want to use Home Assistant.

Little devices like this are popular amongst some Diabetics for displaying their continuous glucometer data (I built something similar using an eink screen and the Dexcom home assistant integration). It’s fun to see what people use these for!
