How does anyone know how to do anything??
I think if you really wanted to make this 'Pi Zero detector' you would go ahead and do it by starting with a google search?
I will offer a little limited help, I don't really know anything about this subject so take it with a pinch of salt.
[*]First google for the term 'web scraping' and read the wikipedia page.
[*]Next decide what language you are going to use (If you don't know a language then pick python and google for some beginners guides)
[*]Write your program
The process should take about 4 or 5 hours for someone with a little programming knowledge, probably a lot longer if you have no computing knowledge.
I think I have heard that there is a library called 'beautifulsoup' that simplifiys web scraping with python try search for that.
Otherwise something as simple as a cron job running a script with wget and grep to find the relevant markup '<div>' maybe easier?
Also it maybe better to use a library if there are more complex protocols involved like if authentication or cookies are used on a site, I seem to remember that mozilla released a project that created a fully scriptable virtual web browser that allowed scripting of things such as mouseovers and flash interactions, I forget what it was called (I'm sure 20 minutes on google would give you the answer).
Go forth and create
