I do not recall where I came across the fact that it is temperature compensated. At some point I thought perhaps the indoor sensor was trying to provide a barometer reading and I placed it outside in a sheltered area, and imported it into weewx as barometer and still it was all over the place. Recently I build a constant temperature box and placed the sensor inside, and for the first time it followed my local airport altimeter exactly.
Conclusion - garbage. I ended up building a BYOD station which I am very happy with On Wednesday, 1 May 2019 12:00:25 UTC-7, V. Kelly Bellis wrote: > > @Louis De Lange, thanks for mentioning this.
