I built something like this. I am amused that mine too was built for my wife and also was one of the few techie things I've ever done that received unqualified spousal approval.
Mine shows weather and tide times at my wife's rowing club. It has the form-factor of a large fridge magnet. This led to the need to be battery powered and therefore very frugal with power - so a RPi wasn't feasible. It uses an ESP32. The data itself is collated by an AWS lambda.
