Introducing Simon 5!

Simon version 5 is now available. It is a massive update, introducing a much-requested feature: syncing the Simon data between multiple Macs, plus a Simon Status service, a Link Checker filter, improved Find filter, iMessage and Speak Error notifiers, a new app icon, and much more.

Important: please note that Simon 5 requires a minimum of macOS 10.12 (Sierra), and is a paid upgrade from Simon 4. Purchasers since September 1, 2020 automatically get a version 5 license (that also works in previous versions).

Read the Simon What's New page for details.

Monitoring a website for changes

I'm new to Simon and have found it very useful for monitoring remote servers.
Can someone clarify how to monitor a remote website (not my own) for changes on that website?
The webpage in question changes rarely, but I'd like to know when it changes.

Re: Monitoring a website for changes

Hi Bill,

Just add a Web (HTTP) service and enter its URL. By default a Change filter will be included, which will detect any changes on the page. If you want to narrow it down to a specific portion of the page, e.g. to avoid any dynamic content like ad banners or relative times, you can replace that with a Block filter, or one of the others, depending on your needs.

You can also add notifiers to get alerted of changes; several notifiers are provided, plus you can add more, typically ones that require configuration before use (e.g. email).

If you have any more questions, let me know. I'm happy to help.

Re: Monitoring a website for changes

So the default filter (When Success use filter Change with input Response Text) is what I want?

Yes, unless you want to focus the change detection on a specific area as mentioned.
