I don't know if this has been brought up yet, but in amateur radio we use weather data with a mode called APRS (Automatic Packet Reporting System). We can report weather data through the APRS packet network over the radio using 1200 baud AFSK packet. One of the things that has fallen away over the years is APRS weather station because there are not that many weather stations available that output a serial stream to parse and transmit. Ultimeter is pretty much the only one left that I know of, but they start around $400. It's a bit much.
I dove into starting to build my own weather station around an ESP32 that would basically take in simple sensor data (temp, humidity, pressure, wind speed and direction) and format into the classic Ultimeter format, but I have really not gotten anywhere with it. Then it dawned on me, WeeWX is already bringing this data in, why couldn't it format a $ULTW string and spit it back out? I am looking at a few different AcuRite stations with USB interface (mostly what I see listed on the WeeWX list) and I think I have settled on the 1036M. I want to use this station to gather the data, feed it to WeeWX on a Pi and have it spit out the $ULTW formatted string on the UART pins so I can feed that into a TNC/Tracker for the APRS/packet side. Am I reinventing the wheel? Has someone already done this? Googling didn't really turn anything up. A side note, my wife is a meteorologist for NOAA and also an amateur radio operator. She recently got the OK to set up an APRS Weather station at her office, so this has kick started me to look for a solution. I'm a radio guy by day, so I have the radio and TNC stuff covered. It's getting the weather data formatted and to the radio that I am stuck on. Thanks for any help!
