I recently ran HeavyWeather to change the Data Logger Interval to match Cumulus and while I was running the software, I noticed that it would appear to get a Receipt or Confirmation of Data Received which in turn Flashes a Red Light to show that HF Signal was received.
I wonder if this data marker is sent by the Thermo-Hydro Sensor and understood by HeavyWeather, if Cumulus has the facility to do something similar?
It would prove helpful in the same way it does for Watson/Fine Offset Stations.
Anyway, I know your busy but just a thought
