I haven't done this, but I'm willing to help out if you need it. What I would do with that set of requirements is to run Weewx normally, with a skin of your choice and the regular SQlite DB. I'd write a little piece of python code to read the db every 2 minutes (or whatever your interval is) and then do the formatting and writing to UART. I've done something similar for myself where I have a piece of python code that reads the db every 2 minutes and sends out a MQTT message that I use elsewhere. The code to do it should be pretty trivial. Turning the python into a daemon that runs automatically is also easy to do.
I'm sure you could do it with a custom skin and some javascript.
