I think no. Indid buy one for testing but it looks like it uses encrypted messages and would not work.
It’s a goner then. It’s been trying to worsen my hearing loss for no apparent reason every now and then since we moved here.
Considering I have an AJAX System alarm in a box I’ll just skip the headache and set that up instead.
I installed Visonic Proxy and tested it with both Dave’s and Mark’s integrations (socket and websocket mode), and it worked fine. The only problem I had was that on several occasions after this my alarm panel stopped connecting to Visonic’s PowerLink servers, and I had to repeatedly email them to reset my connection. So I have briefly undone that while I try to find out the cause of that strange behaviour.
