Firstly I cannot get into the Wholehome web interface using the link I get the message
This site cannot be reached check if there is a typo in mybtdevice.home DNS_PROBE_FINISHED_NXDOMAIN. I can get into the web page by using the master disks IP address and password. However, I'm sure there used to be a second page with more advance settings you could alter with such things as legacy devices etc. You had to enter a different word at the end of the address bar but can't remember what it was plus it's academic as I can't get in via mydevice.home Has this page now been removed?
