What wired relays can be connected to the system? The best option - it's USB relay or Arduino. Tell me, how can I connect a low-cost runtime module to the system?

If you've got an Arduino board, perhaps you could setup an HTTP server on there that could listen for requests and then report the status of each relay as well as expose endpoints to control the relays. At that point, you could write a simple InControl plugin to interface with it.

If you want some help with the plugin, you can ping me on Skype (chumad_rs).

I am also looking at different ways to connect relay contacts and or analog/digital inputs. I am considering an Arduino or a Raspberry Pi too.
I am looking to control two garage doors with separate up and down buttons, so I would need 4 sets of isolated contacts.
Today I found this device;

I have not ordered one yet.
There is also a larger unit supposedly in the works, but it is still vaporware as near as I can tell.

I'll be watching this thread if you find something else.

Newbie here, sorry in advance. I'm interested in using one of the MIMOlite devices to serve as Z-wave inputs from multiple outdoor motion sensors. "Outdoor" seems an elusive target currently so I thought of taking a step back and trying one of the Driveway Patrol packages. http://www.amazon.com/1Byone-Driveway-Infrared-Receivers-Transmitter/dp/B00JR2UZSY $26 for 2 wireless sensors - battery driven, no battery life feedback, definite compromise and a single receiver that can be driven from an AC adaptor. I would need to get into the internals of the receiver which is used to drive an onboard chime when motion is detected at either of the sensors. Instead of driving a chime, drive a dedicated MIMOlite input so Incontrol would know motion is sensed. I would ultimately want 2 Z-wave inputs - 1 for House Front, 1 for House Rear. I would have 4 sensors, 2 transmitters, and one MIMOlite to get what is needed into Incontrol so I can create a scene to drive outside lights. I would have the transmitters and MIMOlite somwhere inside the house so the Z-stick can read it. All the hardwiring would be at that single device, probably a box of some kind. The main challenges will be getting Incontrol to recognize the inputs. Another will be driving the input instead of the chime but I suspect that will be the easier of the 2. To keep cost down, I would want all of the inputs on a single, 2 or more channel MIMO but could live with multiple single channels MIMO's if I had to. If that could be pulled off, I could get decent outdoor motion sensing and control without breaking the bank to do so. I've seen mixed opinions but most are happy with the sensing aspect outdoors of these things and hopefully someday standard Z-wave sensing could simplify this hardware scheme. Any experiences with either the MIMolite or Driveway Patrol would be appreciated.

If you just want an outdoor rated motion sensor, you could check out the Aeon Labs Multi-sensor. They are rated for outdoor use. I have three of them installed outside and they have been working for over a year.
They can also optionally be powered via mini USB so you don't have to change batteries.

More goo, sorry for getting windy. I used a combination of an Arduino board ($25), a 2 channel relay module ($6), a screw Sheild ($4), and a dedicated 9 V supply ($6) to interface between an existing garage door opener and my brand new Incontrol system with a Z-stick. I used a Linear FS20Z relay ($34) and an Ecolink tilt sensor ($33) on the door itself. As this is my first exercise with z-wave, I think I will need a repeater to get more reliable feedback from the tilt sensor. The Linear relay has been rock solid once I learned the correct way to include it. 2 very fast pushes of the button instead of a single push as decribed in instructions. I choose all this hardware based on the functionality of the Linear door control that Lowe's sells ($99) and doesn't seem to work with anything. That is supposed to have an audible beep for a few seconds prior to the door actually starting it's motion. I heard that was an "informal" regulation in CA to minimize injury in an un-attended door closure. Maybe good, maybe not but I thought it worthwhile to include if liability does become an issue. If you don't need the alarm at start of door sequence, the control can be executed by the 2 z-wave products alone. A box of some kind will need built for the Linear relay.

I choose the Arduino to keep costs down as the only wireless function I deemed critical was the initation of the door sequence. Once that happens, the remainder is a static function through completion. Timing can be adjusted but that is minor and still availble on the Arduino. I initiate a command to close the door from my phone. It is a one second toggle that is sent to the Linear relay. That relay closes and wires on it serve as an input to the Arduino board. Once seen, it starts a timing sequence. With the sequence in motion, I turn on a hardwired output that has a cheap buzzer ($2) connected to it. Anyone standing there would hear that before the door moves. Cameras are well down the road btw. For $3 total, I added 2 poreclain light holders. Those are wired to a 2 channel relay board connected to the Arduino. Those relays are used to isolate house line voltage 120VAC from the board. The lights are also flashed at a different interval to provide local warning that something is up. I never have enough light in the garage so I added a toggle switch to the box ($3) so I can over-ride the control and turn on 200 watts of lights whenever I want. Before the flashing sequence is over, I drive the second Arduino relay for a one second pulse that connects to the door opener directly mirroring the hardwired wall button for the door. I have no doubt a seasoned programmer could do all of that with Z-wave hardware but I suspect it would cost a lot more.

Arduino makes single, 2, 4, and 8 channel relay modules. You could use something with all those relays for a low cost Christmas light interface perhaps. What isn't direct yet is conditioning the Arduino I/O for Z-wave. They do have Ethernet though so that might be another way around a specific problem. For now, it was a relaibale, low cost alternative for my garage door. Again, if you didn't need the alarms, you could do it for around $70. I would like to see a Raspberry Pi serve as the gateway with the Z-stick so I didn't have the power consumption of a dedicated PC but that might be a real trade off. I don't think the Z-stick works with the Pi at the moment. Intel has a new board that might be another alternative.

Probably more than what you asked for.

I've seen a lot of mixed reviews about almost all of the multi sensors. As long as the motion aspect works the rest would be gravy I suppose. The mini USB would be attractive as winter gets cold. Any issues with sensitivity? Thanks for the replay.

Yes, the sensitivity of the Aeon Labs Multi-Sensor can be somewhat unpredictable. The devices are infrared triggered so they seem less sensitive when it is warm out than they are in the winter.
One of my three units falses when it is extremely windy.
Everything on the Multi-Sensors works fine in any weather conditions with the exception of the temperature sensor. All three outside Multi Sensors plus two others which are exposed to out side temperatures but not rain, exhibit obviously erroneous temperature readings as the actual temperature gets below freezing.
As a motion sensor I find the Multi-sensors to be acceptable or I would not have purchased so many of them.

On a related note I have recently purchased a Schlage RS200HC which I have mounted to the side of a tree near my driveway. The manual specifies that this device is for indoor use only. However I sealed all the seams with electrical duct seal, which is a gray modeling clay like substance available at any home improvement store. Duct seal stays flexible in any temperature and will not be difficult to remove when the battery needs changing. The CR123a battery has been in the device for several weeks and still reads 100%. From the reviews I have been reading the battery in these might last for a year. So Far the motion sensor seems more predictable than the Multi-Sensors. You might want to give one a try.

If you still want to go with a relay you might consider buying an inexpensive motion activated yard light and substituting a 120 VAC relay in place of the light. There are many such relays available at Digi-Key. You can connect the dry relay contacts to your MIMOlite or to an EverSpring Door/Window Senor (These have an input for a doorbell button closure).

My two cents anyway.

Good Luck
