I miss @datadiffusion when it comes to the ebay topic...
unlucky.....
If its new install set your smartcom up to provide a freecloud a/c at home / work
then your taken a proven set up on site
( I find a lot of time is wasted messing around with apps, routers ect... for little of no income)
Press did then the master code
If you don't get the options to view the log, change time & date, add change user ect....
You don't have the master code
You can't change users via engineering menu
I'm certain I saw the BT Visonic alarm being sold in in PW World or Argos over 10yrs ago
I would be very surprised if any one at BT even knew they once had it as product
