I agree about the PI's usb, but I'd like to warn about over-voltaging the WH1080/3080 as well.
I can't remember where, but I saw a suggestion about using some diodes in the USB lead to the WH3080 to reduce the voltage, which suggests that something is getting near its max.voltage. I was thinking of doing that modiification some time, and after I'd tried connecting to my WH3080 to a new pi3 18 monts ago or so I wished I had. It came with a new '5.1v psu for more reliability' The result was bad - it looks like the extra voltage caused somthing bad to happen to the memory and I've not been able to extract any data from the console it since. The screen is good, but all memory-related stuff is corrupted, and there's no history available on it now, even with the console entirely freestanding. What I did for 18 months was use an SDR to decode the signals. That wasn't 100% reliable though, and the 2 different packet types arriving at different times confused weewx / WU. What I've now done is unsolder the radio module from my moslty-useless console and connect it directly to the pi, along with a BME280 pressure/humidity/temp sensor. its been working for 24 hours now, so I'm hopeful!
