Raspberry CPU temp

The temp today of the raspberry cpu was 61.2 C.
The temp in the upstairs room was 38.1C. Outside nearly 40C.
Is it possible to either show the temp on the interface or an alarm?

There is a webtag for the measuring the <#CPUTemp>. I am not sure which version of the website you are using. If you use CumulusUtils it is possible to add the webtag as part of a UserReport.
Also RPi 4 do run hot, I cool mine with a metal ArgonOne case. We do not get outside temps of 40C but currently the room temp is 19C and the RPi is at 45C.

Actually on my wxstatus page (Saratoga template) I have incorporated this tag into the data I return

For what it's worth, today I installed my RPi into an Argon One case and had a drop in CPU temperature of 20-25 degrees. I'm running an RPi4 and previously just had passive cooling. With the hotter temperatures at the moment I noticed the CPU temperature getting up over 70 degrees so thought it time to invest in some decent cooling.
We got up to 32 degrees inside today and the CPU remained under 50 degrees. I can definitely recommend the Argon One if you're concerned about CPU temp getting too high.

My front office can get to around 35°C when it's closed off from the next room with AC.
The fan assisted case usually has it sitting at 42° on those days.
Wandered in there yesterday & saw 76°C on the taskbar....
Fan spinning at about 60-100 RPM.
Lid off, sticker peeled back for a spot of machine oil & it was back to full speed & temp down to 42° within a few minutes.
Very good argument for Passive over Active Cooling.
Just been stalled on choice of case.
Pi4 on my own site, rPi3B on another.

The good thing about the Argon One PI V2 is you can configure when active cooling is required. By default, under 55 degrees and the fan remains off; at above 55 degrees and it operates at 10% power; above 60 degrees and it operates at 55% power; above 65 degrees and it operates at 100% power. You can configure it to kick in at whatever temperatures you like though.
