well john the sht31 issue is not widespread i live in a warmer somewhat drier climate than you see on average in the UK and seasonal high humidity and dusty drier periods.ive not see any discrepancies with the sht31 used here , ive seen bottom end readings of 10% under certain conditions south easterly dry winds note i live by the sea ,ive seen 100% humidity under dense fog conditions the type with extreme low visibility and creates a layer of dew on everything..no offsets applied...
as for a vp3? console if they dare call it that it quite rightly doesnt warrant a different model number moreso call it a console-plus
.personally build upon this trusted brand and model and continue there yearly subtle upgrades ...i.e tipping bucket,wll...
as for apps replacing console probably a likelihood but i hope manufacturers start producing a fallback when that 24/7 internet isnt available be it a natural weather disaster , or a natural disaster event or just routine ,unforeseen downtime..a lesson learnt from cloud dependable services ,api services,just look around this forum they are not a reliable solution..
first hand experience of using a weather station piece of hardware that has a dependency on a app to provide data and to configure the initial install,the moment the internet drops or an outage occurs it relies on a compatible bluetooth connection..
so a console-plus would be seen as ever a reliable solution..
galfert if davis produce a pm 2.5 it would be advantageous for them to design a dedicated product as an add on and be positionable ? but it opens up other backward compatibility issues with consoles so perhaps a console-plus would be on the horizon..please don’t misunderstand my qualms with fine offset products they are real world dissatisfaction and experiences and having dismantled them in the past im amazed just how crude some of the past models ever got past a qc check..perhaps they have improved ?
as for the op original question if you can justify the cost spend your hard earned money on a trusted proven brand and build upon on it as time goes bye..as you discovered with the accurite however will a fix of the aspirator not buy you time to decide..
