IMHO an outsider like me can not know if it is high or low. And neither what is causing the “way more” bandwidth.
Be aware that when posting questions on a forum, people tend to take a look as that is the only way to help. These questions are not private 1-1 conversations but public “cries” for help.
First: Were you already running a previous version of weather34?
To at least check what is going on, I need to have the URL’s to both your previous weather34 and the current HWS-template as it is called now.
Second: If this is your first “dynamic” website:
All versions of this template are continuously refreshing the data at the browsers of the visitor. Some parts every so many seconds, others every so many minutes. Those are not large chunks of data, but it adds up when using 24/7 an iPad as a console.
Also the scripts refresh “too old” forecasts, metars, and other data files like earthquakes. Normally that will be done when the cron-job runs. But these files can be larger. You have to inspect the …/pwsWD/jsondata/ folder for files reloaded today. And check how old they are.
All files have a different validity time, a forecast once every hour, a current condition file every run of the cron-job.
