Do you know if the Aranet4 can be used over bluetooth/wifi without internet access? I've been looking at a bunch of devices and haven't seen aranet yet.

Also, have you ever put all of your devices near each other to compare the variance between them all?

AraNet4 does Bluetooth, yes. Mine is doing that right now.

You can get wifi bridges as well, see https://devel.aranet.com/products/

ESPHome on a ESP32 makes a nice Bluetooth2Ethernet Bridge.

I've seen Aranet4's on eBay for under $150 pretty regularly, so I'd look there.

I got my Aranet4 because it had very good reviews and allowed local read out of sensor data without any "cloud" involvement. I've been very happy with it, the readings are integrated into my Home Assistant setup so automations can respond to high CO2 (e.g. turn on a fan directed at a window, when temperatures are high enough to have a window open).

I wrote a bridge to get readings in to Homekit and prometheus as well. Useful to track multiple sensors and process historic data easier than the app
