Hi Stephen,
Thank you for your reply. I was hoping you would comment, and yes, I've read through that thread a number of times and am a little less intimidated with each reading. There is much discussed that is unfamiliar to me, but even before embarrassing myself further in that regard, I have to confess my naivete in thinking that the sensor data was accessible to me without limitations and able to be archived locally, should that be something desirable.
I'm not sure how data is sent to Weathercloud, Weather Underground, and PWS Weather; e.g., is it sent directly from my display console to those sites, or is the data being relayed to them from AmbientWeather.net? Is Ambient the gatekeeper?
If I'm understanding your radio project correctly, data transmitted (@ 915MHz) from the outdoor array is what is being received, bypassing the display console altogether, and the Raspberry pi then is relaying the sensor data (@ 2.4GHz?) - is this understanding correct?
