I was thinking that you could use the digital input to count the number of times the bucket in rain gauge is filled and then emptied.
Marc,There's another thread on the HomeSeer message board where I posted this info:

The CAI WebControl printed circuit board PCB is 80 x 88 mm
The outside dimensions of the case are 100mm x 100mm x35mm. The case is well-made from steel with threaded (not sheetmetal) flush screws. There are four standoffs inside to which the PCB is attached with screws.
It is roughly the same footprint as a Comtrol DeviceMaster Air http://www.comtrol.com/products/family/dmair and a Netgear 5-port hub (100x 92mm). Together they make a complete wireless system together that can be expanded to include an RS-xxx device and provide internet connection to up to three additional devices or redundant wired connection + 2 others.
DeviceMaster Air --> Hub --> Comtrol TCP/IP->RS-232

I am working designing a companion PCB that would fit inside the CAI WebControl case and provide:
1) Regulated DC power for the WebControl and companion PCB
2) Multiplexor for additional analog and digital I/O
3) Amplifiers for signal conditioning
4) DPDT relays
5) Optionally:
... a) Analog signal differencing / comparators
... B) Power for other devices
... c) Be powered from standard 24VAC HVAC transformer
... d) Be powered by Power Over Ethernet (POE)
... e) Trickle charger for battery backup.

I am more than willing to set up a subforum (just like we did for HAI/ELK/etc.) if there is enough interest. Would make it easier to find this information, without having to invest in your own forum platform.
CAI_Support,
Great to see you here!
I was wondering, the web page states 8 Temperature sensors. I have a need to put in 10 sensors, is that possible? That is, maybe use one of the digital I/O ports?
I want to get something that does 1-wire...and have been oscillating on 3 things. I think the easiest would be to use the Webcontrol. Next "harder" is t buy a serial/USB adapter, gives me a bit more flexibility, but I will end up paying for the device (they cost about the same as the WebControl...but I'd be losing the extra Digital and Analog I/O). Finally for $5-10 less than both, I can get an Arduino and write my own...which lets me have the ultimate in flexibility...but I end up paying in time (which I am short on right now).
I have a use for some Digital Outs...so I end up getting the WebControl, or getting a 1-wire adapter+digital out device (total cost ends up being more). I realize the 1-wire on this is very basic (hence no "full" support for talking to all 1-wire type devices).
Thank you for your assistance!

Dan,
Thanks for your question. WebControl board we are selling now is a 8 bit board. We are also developing a 32bit WebControl32 board that may come to market early next year. Current WebControl board which we call it WebControl8 has 8 of everything, temp sensor, input and output, VARs.
WebControl32 will have 16 of everything, double the I/O. Of course, its cost will be higher, too.
We have little code space left in the WebControl8 board that we can add more temperature sensor, or I/O. But we are thinking maybe reserve that space for support LCD and kaypad. The LCD and keypad will be attached to the 1-wire bus. Then through PLC programming, you can display your own defined message on LCD, and push the 12 button keypad to enter your own code, like those alarm system, or for machine control purpose.
We love to hear your input, so that we can develop it fit most people's need. If most people like to see more temperature sensors, we can add more temperature sensor support on WebControl8, if people like to see more digital I/O, we can make option I/O board and add logic to that, too.
We want to make this as flexible and useful as possible.
Please let us know what you think we should add first.
Thanks
