Temperature switched from Celcius to fahrenheit all the sudden!

So I have 3 three rpi’s around the house. Everyone is added to Librenms to show temperatures via a external temp sensor. Allthough I’ve hadde issues when the temps goes below 0C, something new happend today(?)
The sensor on my Librenms rpi all the sudden switched to Fahrenheit! But it shows as Celius, but some there is no way there is 48 degress C where the rpi is running. It’s on running in a ventilated loft. So when I run python code to display the temp on the external sensor it shows me:

pi@:~ $ python tempsensor.py 
21/02/25@09:30:48 - 8.2 C
21/02/25@09:30:51 - 8.2 C
21/02/25@09:30:54 - 8.2 C
21/02/25@09:30:57 - 8.2 C

And Librenms displays this:

And my other 2 rpi’s displays like normal (the sensors is indoors)

I tried to run the ./discover.php -h 6 -d | ./pbin.sh and of course got this:

curl: (60) SSL certificate problem: certificate has expired

curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the web page mentioned above.

I think the cert was fixed a few days ago - try and upload the debugging data again.
