Murdock, that's great, the more usage of the panel the more bugs we can catch.
You don't have to worry about the panel model, all Vista series are supported by the current Thom's driver, but you have to have the Vista-ICM module installed, that's how LMCE talk to the Panel. So far it works great with minor issues, the countdown on the squeezebox get stuck in a loop which I just filed a bug report, the other issue is, the current Panel only works with attached wired sensors or compatible RF transmitter (345Mhz) using the "5881ENL Receiver" which I just installed myself yesterday, you can not use already installed zwave sensors for an example, the reason is, you can not force the panel remotely by commands for an alarm on certain zones, the only way is to bridge it, for example connect a Global Cache output relay to one of the panel free zones, if the zwave sensor get triggered you can send a command to the Global Cache to open or close the relay in which case it will trigger the alarm on the panel. That's the easy way if you have the Global Cache which I don't, maybe someone can advise on other solution here, the other way which I'm investigating through transmitting the RF command to the "5881ENL Receiver" which I asked the Honeywell engineer he said it is possible, and he suppose to email me the protocol spec, I will share it when I get it.
Again the whole idea of the panel is adding extra security to LMCE in case of an extended power failure, and extend the compatibility to new sensors on the market.
