So I got an Ambient Weather 2902C unit and an Ecowitt. I noticed the Ecowit uses a USB and a four-pin connector. Does the Ecowitt have to be plugged into the weather station and the Raspberry? I am still a little fuzzy on the communications method to get this working. I was reading, and I read many posts saying the OberverIP wasn't a perfect solution and to use the Ecowitt. Still, I am not finding a lot of information on how to get these set up, and with the variety of the stations, it seems steps might follow a few different stations.
I have read we have to use the PI to grab traffic from the unit talking to WUnderground, which I have setup. But capturing that traffic is just not clicking, especially with this Ecowitt in the mix. Should I get the ObserverIP?
Thanks all. I don't want to rehash the wheel, but I am drawing a blank on these steps, no matter how much reading I am doing.
