I doubt it takes much more processing power to access the serial port on an RPi, than on any other machine --- the baud rates are pretty slow --- but, I could certainly be wrong.
I have also had mysterious increases and decreases in my rxCheckPercent. There was one period a few weeks ago, when it fell into the 50% range precisely at midnight, stayed there for 3 days, then went back up to 99%, again precisely at midnight. You can see it here <http://www.threefools.org/weewx/monthrx.png>. Go figure. -tk On Tue, Jan 24, 2017 at 10:58 AM, tds <the.dawning....@gmail.com> wrote: > I have recently migrated my weewx setup (with a Vantage Pro 2) to a > Raspberry Pi 3.
