    It seems a good weather station with a console and software to display the results

    It seems a good weather station, and communicates with the console, which then connects to the Internet and weather websites. Unfortunately, initially, the console didn't work as it should.

    Weather Spares quickly dealt with the problem, updated the firmware, and checked that the console worked properly. (They paid for the postage both ways.) I connected it back up, and got the same problems. As Weather Spares had had it working properly, the most likely cause was the USB port I was using. I tried different ports and found that all the ports on two USB hubs would not talk properly to the console, even though they appeared to work with USB disk drives, etc. So if it doesn't work properly for you, try different USB ports.

    I also tried the console on my Windows 11 laptop. It worked straight away.

    The pictures are examples from the EasyWeather2 output. The first is of "live" readings, the second is a graph of barometric pressure changes over the past few days.
