Here’s a couple of weeks worth of data from outdoors.
Dew Point is the dew point value from my weather provider along with the temperature and humidity sensors. Dew Point Test is Stimo’s integration with data points fed from the same weather integration. Looks like the weather integration is actually using the Lawrence formula which is a little disappointing. Anyway, Arden Buck consistently has values below the Lawrence and as expected the lower the humidity values the more the 2 methods vary. Above 90% the difference is down to 0.1°C.
The indoor data shows the same results as the outdoor.
