2 stars Be Carefull Here
My use is to integrate a third party Modbus gateway (GWY-141)to collect and display on a SCADA page. That process is still ongoing. However I am dissatisfied with the cross platform integration provided by Davis software, more specifically the Envoy8X DTU to WeatherLink data logger integration. So far, it works great if your willing to have a cable connected directly to your console provided with your ProVantage station. Expensive stuff for not being completely integrated out of the box!
