I have a whole house filter in the mains cabinet. Primarily for noise. Not the issue you are trying to track down.
AHP has two tools: Find Other Computers; and Activity Monitor, which you are probably familiar with. The only thing I can add is, I have AHP on Windows 10 Pro. This way, I can access AHP with a laptop using Remote Desktop Connector and move around the house to troubleshoot. Only the PC where AHP is hosted needs Win 10 Pro, the laptop can be any version.
Set up is simple. On the host PC go to Windows Explorer, right click on This PC, then click on Properties. Click on Remote Settings, click on Allow remote connections to this computer, click OK.
On the laptop, a quick and dirty way to access is in Windows Explorer. Click on Networks, find the PC. Right click on the PC and select, Connect with Remote Desktop Connection. Happy hunting.
