As for PFMonitor it is difficult for us to promote that as we are looking at our own central management development that includes extending the API (you can utilise this too when available for PFMonitor as the API extension is part of the open source OPNsense project).The central management solution will be part of our open source business model so we can extend our team and increase the development effort.This does not mean that there is no room for you and others to provide their own solution, just that we as Deciso are not interested in third party solutions at this point in time.
I'm also very busy, but if you can provide me with an account to your solution and the necessary script files, I can see if I can try this myself.... but no promises.You can reach me at (email-address).Best regards
