Thanks for making this statement.....

"I wonder if your picking up some noise on the wire between the sensor and the PiFace. "

A light bulb came on when I read it.

 

I am a Ham Radio operator and made a couple of contacts today on the HF band around the times it was happening.  Hmmmmmm

I confirmed this by doing a tail -f on the log file and did a transmission on my radio and open and close statements started scrolling across the screen until stopped transmitting.

The wire from the sensors to the PiFace is a long antenna.

 

I will see if I can put some filter on the sensor wires but in the mean time I guess I don't use the radio when my system is "Armed".    Should not be a problem for now.

 

Thanks for your help.

Or a RaspberryPi with a PiFace IO Board.  I do this for my wired door sensors and will for wired PIR's as soon as I find a wired PIR that I like.

Hello Xathros,

 

I liked your idea with Raspberry Pi and went that direction.  I wanted an excuse to play with a Raspberry Pi.

I have it all setup with a PiFace and a Python code I wrote.  It is hooked up to three hard wired door sensors.

It has been running for the past day and working just as I expected.

 

Today I noticed something looking at the log from the Python program.  A couple of doors started reporting open and then closed very quickly for a couple of minutes, each door at different times.

One of the doors is one we do not use often and was not used today.

 

Have you seen this?  

I am wondering if it is a timing issue and maybe I need to recheck the status before telling ISY the door is open.

 

Thanks for your help.

I have an old security system as well as many Insteon modules.

The security system has died.  

I don’t really need the full security system but would still like to be notified if someones comes into my house when I am not there.

I am looking at the ISY994i to do this as well as control my insteon modules.  I currently have the Insteon Hub.

From my old security system I have three wired door sensors and three wired motion sensors that I would like the ISY system to know when they are opened/closed and to alert me about via text message.

The door sensors are two wire and the motion is four wire to supply power to them.

I assume I could get an I/O Linc for each sensor but seems clunky because I  would have to figure out how to get six electrical outlets in the location the sensors terminate or re-route them.  Plus I would have to figure a way to get the correct power to the motion sensors.

I am guessing it may be cheaper and less of a hassle to pull out the existing wired sensors and go with the Insteon sensors. I just don’t like the idea of changing batteries in them every 6 months.

Has anyone else found an easy way to use wired sensors with the ISY994i or is just best to go with Insteon ones.

Thanks for the feedback.
