Is there a way to get the devices (zones) from the Elk? Or do I have to set each one up? If so, how? I read elkm1.htm but it is over my head. Like what is "4 state (multi-state) inputs, etc.?

Jack,

Unfortunately no...PowerHome is unable to query the ELK for device information within it (my understanding is that the protocol that does this is proprietary and not available).

A 4 state input is just Elk's standard "digital" input. I think of a digital input as only having 2 states...off and on. This is like what an Ocelot or a K8000 uses. ELK however has the ability to configure it's inputs as either analog or what I call a 4 state input (it actually has 16 states...but that's another story). These inputs are referred to by Elk as "zones". It may help to look through their RS-232 protocol manual. Don't dwell on the protocol or the details, just skim the messages that are available and the values that they return. This is ultimately what PowerHome is based upon.

In the case of the 4 state input (ELK zone). It has 4 logical states (Open, Short, EOL, and Unconfigured) and 4 physical states (Normal, Trouble, Violated, and Bypassed).

I plan on putting together some setup information for beginners on certain aspects of PowerHome such as the Elk.

Dave.
