Thank you for forwarding it! I'm closing it for now (leaving the open issues list only for pending bugs) and marking it with the wishlist status labels (so I can revisit it later).

That would be great!

The problem with that patch is that it spawns a new process on each screen update. A more native solution would be welcome!

👍 for OSX too
updated readme

We faced this user wish as well and for my impression it indeed would really fit well into htop on Linux. We found so many 3rd party patched/implementations, but all of them have heavy dependencies and/or are not well implemented into htop (as above).
Many devices safe their temperature info readable inside
/sys, but of course the file path/name varies...Check our method as an idea, at least it covers some devices 😉: https://github.com/Fourdee/DietPi/blob/dev/dietpi/func/dietpi-globals#L802-L809

@MichaIng thanks for the pointer! indeed, the lack of a standardized interface is disappointing. :\

Indeed, looking around a bid, I found
lm-sensorsto be a popular module, showing (CPU) sensor temperatures. It needs to run a sensor detection command first, which seems to scan/check several different/sysand/procfolders, depending on existent kernel modules, in case enabling modules to access temps: https://github.com/groeck/lm-sensors/blob/master/prog/detect/sensors-detectLooks quite messy for implementation. Just scanning some most common default locations and provide CPU temp meter just in case one with reasonable output was found, also is not too secure, as users report values of constant 40 °C or simply from other non-CPU sensor.
No problem, if supporting just a limited amount of devices/hardware, but for htop a deal breaker.
