Hi All,
Is there a such thing as usb thermometer that Fedora can read? And be able to be place a ways away from the computer so the computer's heat will not throw it off?
Many thanks, -T

I have seen some USB ones, but it's not clear if they are just dataloggers or you can get constant readings. There are also bluetooth ones which would give you a lot of range. However, if your computer doesn't have BLE, you will need to get a USB BLE bluetooth dongle. That's what I did.

Hi!
USB I don't know but the Mijia thermometer is BT and Fedora can read its broadcast through gattool. It runs using a AAA battery which is supposed to last for about a year.
Hope that can help you.

Of course there are. Try to search for "USB Thermometer" on AX and you will find many like this: https://www.aliexpress.com/item/32869421298.html Around $5. I use this, there is software floating on the 'net.
cheers

This may be a silly question, but what are you measuring? If it is the local room temperature, you have several sensors on most motherboards, and one or two will be pulling room temperature - e.g. most disks are mounted in the room-temperature airstream. If this is on a server, then every one that I have also has an intake temperature sensor to control fan speed.
Of course, this will not work if you're trying to measure the oven or outside temperature for instance.

I didn't have any trouble searching for wifi usb thermometer and getting lots of hits

It's not USB-based like you asked for, but I wanted a temperature and humidity sensor I could place anywhere in the house and which could be read by my computer. My solution was to buy a Raspebrry Pi 3 Model B+ and a humidity sensor that plugs into its IO pins. That's ~$40 total cost. Now I have a little computer that reads the temp and humidity anywhere I put it (it communicates via my wifi) and makes those readings available through a web service on my home network that any other computer can query. I could provide more details if this interests you (outside the list, as this would be way off-topic for this list.) It's pretty simple to do, simpler than the web tutorials I found make it out to be. They're all pretty out-of-date when it comes to the software setup involved. That's gotten dead simple now.

Not what I was after, but I am interested anyway. I have had plumbing lines leak under the house before.
How do you keep it charged?

This humidity sensor I'm using is for relative humidity in the air, not for water leaks. There are probably better wireless water leak detectors out there. To answer your question, the Raspberry Pi isn't battery powered but I suppose it could be. They run off USB power, i.e., 5VDC at various amperages depending on the model. The one I'm using for this application needs 2 amps. I run it off an extra cell phone charger I had laying around. So, I assume one could probably use one of those mobile phone charging backup batteries that are on the market to make it battery powered. Not sure what the run time would be on one of those however.
I just made a post on my wiki describing what I built -> http://bit.ly/37hOLu6
