Elements of a Vera-Based notification system

After long consideration of many options, I find that I need a simple notification system for our cabin, not a full alarm system. I am now looking for elements to make this work.

Our house in the woods is already wired with door, motion, and smoke sensors, but the system is archaic and not at all useful. My plan is to re-purpose each of the sensors as inputs directly to Vera to get a notification system. But, I need to find the right interface modules.

Do you folks know of any zwave-enabled input/output modules that I could interface to these sensors? I have not found any generic ones, but am hoping there may be some out there. All I need are binary inputs to a module that will give a simple on/off indication, on which I can then trigger actions.

Barring this, I can get the zwave components from Digikey and make my own. Board design is not that hard. But this may be a bit problematic since the business model of Sigma designs (as of a year ago) was to extract high licensing and development fees for anyone trying to use their modules. Interestingly, their latest module (4102) would be a great fit: zwave radio/software stack and 10 GPIOs. That’s about the perfect number as it corresponds to the number of sensors already in place.

I even offered a business deal to Sigma Designs to get enabled modules out to hobbyists for more experimentation, but that did not go anywhere. I’m now making contact with them again to see if anything has changed.

This is not a hard problem and a simple concept. However, the solution has eluded me for over a year now and I’d appreciate any pointers.

Yes, I’d have to write the plug-in and other interface code, but that would also allow a springboard to other sensors I want around anyway (such as a snow-depth alarm and strain gauges for deck overload).

I have Vera2 UI4 version 1.1.1245. I wired independent baseboard heaters with solid-state relays so each floor could be controlled by a thermostat, and use 4 Wayne Dalton thermostats in the zwave network. Started with Vera1, which was incredibly unstable, but this configuration has been extremely stable for the last year. HomeBuddy is a great interface app, and it’s great to have the heat on when we arrive, but also to be able to shut down heaters that were inadvertently left on.

Vera is a great control/maintenance solution for a second home, and intrusion monitoring and smoke detection would be great additions for my particular use.

@RandyS, why not just buy a new alarm system and use one of the plugins that Vera already supports?

You could probably buy a DSC 1832 system for about $100 and just hook up your existing sensors to it, and then add a dsc it100 for $50 and just use the DSC plugin to interface everything with Vera. This is exactly what I did to interface my house’s existing alarm sensors into Vera. I have >20 sensors and they all work great with Vera.

Otherwise, I am looking into interfacing additional i/o to Vera through a Arduino microcontroller development board with an ethernet module. I haven’t figured out all the details, but it isn’t unknown territory by any means (lots of people use them in similar configurations, so I’m fairly certain I’ll end up with a working project).

I guess what I am saying is there is no reason to tie yourself to z-wave. Vera is quite capable of handling other technologies, especially with serial or ethernet interfaces.

There are “Smoke Detector Relays” that can be attached to the newer 3 Wire interconnected smoke detectors. This could trigger a Z-Wave door sensor and be used for smoke detection.
Also if you wanted to hook up a relay and a 9V power source you could drive 9V on the Red-White wires and use your smoke detectors as an alarm. (The “Smoke Detector Relays” sense the 9V signal on the Red-White wires. I can’t remember how much current you must be able to source … but I think a 9V transistor battery will trigger at least 4 devices.)

I would luv to see something like a 4 Binary Sensor/4 Relay Z-Wave board (Single Z-Wave device).
