[FEATURE REQUEST] Customize update frequency per sensor

[fdw]

Not sure how sensible this is, but I think I'd like to define for each sensor how often it should be updated. For example, it feels like I'd prefer more seldom updates to CPU frequency and temperature. But I'd need to try different values to see which period works best.

Hey @fdw this is a great idea. In 7f8450e I've added preferences for defining the polling interval for the cpu and hwmon sensors! That will be in the next release 🎉

Unfortunately, I can't at the moment add more granular preferences for, say, setting the polling interval of the cpufreq sensors to one value and the cpu usage sensors to another. All of these sensors are currently polled in a batch, so there is only one polling interval for all of them. I should be able to split this up in the future though.

At the very least, hopefully just exposing the ability to control the interval of all cpu/hwmon sensors, which are probably the two most "costly" polling sensor groups, will be useful.

Sounds good, thank you!
