Been doing some research lately and found this good resource for the Davis weather stations. So just saving the link here for future self.

Some Notes
Interesting info on Barometer Pressure.
https://www.manula.com/manuals/pws/davis-kb/1/en/topic/pressure-reading-problems
The intrinsic accuracy of the barometric pressure readings for both Vue and VP2 stations is quoted as ±1mb or ±0.03“Hg and, once calibrated, most units will track other high-quality pressure readings in the locality pretty well and to within this nominal accuracy. There may be some long-term drift, in which case an occasional recalibration against a reference reading should fix any slight problem.
However, stations that are located at significant altitude (eg 1000-2000ft and above) may experience more frequent discrepancies against reference readings. This is not necessarily caused by any fault with the console but can arise because of the way that corrections are made from the measured local pressure back down to sea level. (The more elevated the location, the greater any sea-level correction will be, which is why this issue is usually only noticeable at stations located at significant altitude.)
When I compare my barometer readings to what Windy.com is showing for this area, my station is within 1mb. I do puzzle why so many other personal weather stations in the area are so different. Maybe they have drifted or not been calibrated correctly or is mine off. Since I cannot compare to an official calibrated one, I tried to calibrate mine to the airports in the area on a stable air pressure day.
Another topic of exploration was if I could move my UV and solar sensors to the anemometer mount point so they would never be in the shade. The sensor transmitter has plugs for UV and Solar, but found this text stating that it would not work.

Other transmitters: Users often notice that supplementary transmitters such as the 6332 Anemometer Transmitter or the 6372 or 6382 Temperature Stations use exactly the same transmitter board as the ISS, which therefore has sockets to connect solar or UV sensors. Regrettably you cannot use these supplementary solar/UV inputs. The reason is that solar/UV data must be received by the standard VP2 console as ISS data and the VP2 system allows only one ISS per station. (The supplementary stations will in fact transmit the solar/UV data, but this can only be received by eg an Envoy8X or Meteobridge Pro Red unit.)
