Brad, you can also order that part separately from SH #8015 if you already have and I/O Linc. Back to the EZIO... I want to read outside temperature and indoor humidity to control my Humidifier automatically. I currently have a small wall control connected to outside sensor that does this and works well... but, being a geek, I must try to get the ISY to do it SH # 1523 is a cheap temp sensor that gives an output of 0-5V. If EZIO 4x2 works with ISY to read analog, then it should send a value between 0-1023 and this can be used for logic in programs. I think one may have to run the setup from SimpleHomeNet to put inputs in analog mode. To get humidity, I notice SH doesn't have anything like the temp sensor, but since I'm ordering a bunch of stuff from there I found this... SH # 30413A for Venstar. This looks like they use a standard Humidity sensor that I have seen when doing some research online... it should have Vcc, Gnd and Signal. Although it is designed/sold to plug into a Venstar thermostat, I believe it would work standalone but one would have to calibrate the readings to actual humidity.

I am on watering restrictions imposed by City. Based on my house address, I can water only on odd days. Setting to water every 48 hours will not work because some months end on an odd day. And what if the ISY is restarted? Then the every 48 hours will not run until started again. Anyone figure out how to do this? I have been working on it and have come up with a set of programs that appears to work, although some setup and tweaking every once and a while may be required. I am just wondering if there is some simple way to do this that I overlooked, since I am new to the ISY, before I document and post what I have done. Brian

The I/OLinc only has a dry input. The 5V has nothing to do with the input. I can trigger the sensor on mine by just shorting the GND and Sense and ISY reports it either On or Off. The 5V purpose appears to be a convenient source for running 5V through the relay circuits for controlling power to devices, if it requires 5V. My application requires 12V so I use an external power supply plugged into the I/OLinc. I am told the EZIO 2x4 should work. I have one on order and will followup when I get.
