Gents,
Anyone know where to obtain local weather data that has 20-30min interval readings with humidity in there? This was perfect but last Wednesday they quit updating this station:
In the past I've used this to gauge whether to run the evaporative cooler with or without water circulation overnight. Cold+humid meant it had to run sans water pump or you'd have a damp house. On dry nights it's better to run with the pump or the house is still hot in the morning.
