Unfortunately making a profit and surviving seems a bad idea to some. But its the clients that loose out. Sia have just saved a fair few as the installer hadn't paid the monitoring bill for a fair while.
I would think most started up. But people tend to do this on price, ie ill do it cheaper etc which just reduces margin. I knew of a firm that were charging £28 a year for monitoring digi. No longer around
my 2p i don't see why the installer would want to stop you adding devices. It may be new to them etc id ask them to change it. But i don't know Pyronix gear so it may not be possible
amps you seem to infer that people care about security? If that's the case then its also about the backend too. ie not using dropbox for customer data. No data on the google linked phone?
can you upload the log, its seems odd if on extended reporting you got the open as it was ripped off. As above what communicator, arc and polling rate is setup?
