surprised at the knee jerk reaction here again
It's like buying a car without wheels. Why bother. Get me something that does the job outta the box.
funny it is in your signature a vp2 with optional FARS (extra cost) to keep the temperatures inline . as with the AIR sensor you can buy a 3rd party optional shield or just do DIY solution its not rocket science and your local DIY store probably has everything you need just like a cheap $20 bathroom aspirator which can be easily adapted. AIR is a first generation product just like all products early production runs against later production runs will differ and see improvements as time goes bye. has the VP2 always had a SHT31 ? has the VP2 always had a aerocone rain buckets , improvements always happen over time. as you can see from below
AIR model is not even a year old how old is the VP2 ? im sure in the early days of a VP2 release there were anomalies its the companies that listen to feedback and act upon them which make the difference long term. Weatherflow is listening and acting .

SHT11: The previous standard VP2 T/H sensor is part 7346.166 which has now reached revision J. This part is thought to use the middle-ranking SHT-11 part (SHT-10 being unused by Davis), which is specified as having a typical temperature accuracy of ±0.4°C (at 25°C) and for humidity of ±3% over 20-80% RH, rising to 5% at 0 and 100% RH. The Vantage Vue is also thought to use this same SHT-11 sensor element.
SHT15: In 2015, Davis introduced part 7346.174 which uses the enhanced SHT15 T/H sensor. This option has two main benefits:
In addition to lowering the typical temperature accuracy at 25°C to ±0.3°C, the SHT-15 has an altogether shallower temperature/accuracy profile, which offers a roughly doubled temperature accuracy at eg -10°C and 40°C;
The baseline RH range of the SHT-15 is ±2% over 10-90% RH and maximum error at 100% RH is reduced to 4%.
This 7346.174 sensor is a direct drop-in replacement for the older 7346.166 part and may be used with no change in temperature offset being necessary. Note however that 7346.174 has only been made in limited quantities and may become increasingly difficult to source.
SHT31: The newly released SHT31 sensor is built into Davis part 7346.070. This is plug-compatible with the 7346.166 sensor and can be used with any VP2 station from 2006 on. However: The temperature calibration of the SHT31 sensor is slightly different from the previous sensor and if the 7346.070 sensor is used with a VP2 station prior to the AS revision then the temperature will read 0.5C high and therefore a temperature offset of -0.5C needs to be entered into the console in this scenario. (And conversely if eg an older 7346.166 sensor is used with a VP2 station of AS revision or later then the temperature will read 0.5C too low and an offset of +0.5C needs to be entered.)
