Well, I'm not all that tech savvy. I had a Synology NAS for a few years mostly for file backup and then explored hosting a website for family photos and videos. Then after issues with IONOS web hosting I thought maybe I could host my weather website but feared it was way more complicated that my simple family website. It turned out to be fairly easy but my old server was too slow, so my wife got me the DiskStation DS220+ for Christmas. Synology has instructions for setting up the web server plus back-end Apache, php, etc. plus the free SSL certificate for https. After doing that I just downloaded all my files from IONOS to the /web folder on the NAS and that was about it. I had update some paths in some of the files and tell WD where to send the data but it really was quite simple. The interface to the NAS is all web-based, so I didn't have to poke around in Linux. Let me know if you ever decide to switch and I can point you to some instructions and give you more details on the set up.
After leaving the UK in 1987, we returned for vacation in 1992, 1999 (with our kids) and 2013 (when my daughter interned in London through Florida State University). In 2017, we went to Exeter because I had several days of meetings at the Met Office. We intended to visit in 2020 including spending a week in Scotland but then COVID hit. Now we're waiting for the airlines to get their act together and stop cancelling so many flights, never mind the backups for passengers at the UK airports! I'll gladly meet for a cup of tea if we're in the Cambridge area when we come back.
I too like to monitor adsbexhange. I live 4 miles west of Dulles in northern Virgina, so when the departure path is over my neighborhood in the evening, I like to sit to my deck and monitor what altitude the heavy's (767, 777, 787, A380) are at when they fly over my house. Usually, they are only about 3000 ft high. Quite the sight. I took the attached photo of the pre-COVID daily A380 Emirates flight in 2019. They retired the 380 and fly a 777 post-COVID.
