These are great. I have two of them and access the readings over Bluetooth using some Python code: https://github.com/Anrijs/Aranet4-Python (there's also a mobile app which I've never used)

The eink display is really nice and if you disable Bluetooth the battery seems to last forever.

It's 40% off right now which makes me tempted to pick up a third!

This python code looks fantastic. Worked right out of the gate. Thanks!

Also I was not aware of the Aranet Radiation sensor. There goes some of my fun budget towards picking one of these up.

Also there is a Go equivalent (https://pkg.go.dev/sbinet.org/x/aranet4) which works well on Linux and https://github.com/ryansouza/aranet4-exporter-go can be used to export the data to prometheus.

That 40% off is a bit misleading, more like 10% off, as you've been able to get them for ~$165 on Amazon forever.

The Aranet is wonderful. I have had mine (Aranet 4) running for at least a year on a single charge.

I've had mine for 3 years now and it's great. Highly recommend.

Looks like it got the Hug of Death. Amazon sells it so just search for Aranet4 if the manufacturer's site is still struggling.

I have one of these and have had zero problems, it's easy to use and seemingly very accurate. Incredible battery life too.

Does the app require any clouds to work?

No, for the home version the app just connects over Bluetooth. The protocol is documented and there are robust open source implementations such as https://github.com/Anrijs/Aranet4-Python

I'd love to buy one, but it costs `undefined` USD and won't add to cart

Second this one. I own it and it is great

Yeah, I have this one and it's fantastic
