Glad to help.

Terry also has some great Nordic 2.4 GHz devices, with the basic starting at $4.75 and 200 feet range.
I've ordered a couple because Xbee is REALLY expensive here.

Plus the USD is really favourable at the moment.

Cheers

hey quick question for you. Why do I need the goldline control if I have an arduino??  Why did you interface with yours if you are using an arduino?

I'm probably missing the point.

No, you're not missing the point.  Decoding the Goldline protocol and using it is only a step in a whole lot bigger project that I have in mind.  See, I don't understand the chlorinator yet and have to use the goldline controls for motor and such to make it work.  Eventually, I'll get rid of the Goldline entirely and control everything with my own controller.  Meanwhile, I tried to get Goldline to tell me about the protocol and they stonewalled me.  That kinda ticked me off, so I decoded a sizeable hunk of their protocol and put it on the web.   8)

I think I'll start my own controller off with a simple set of controls for the lights, fountain and waterfall.  Then expand it to the solar heater; leaving the chlorinator and motor control on the goldline.  Then I'll start trying to create my own chlorinator.  When that works, I'll have a complete system.  The lights and stuff are basically easy except for setting up the timers and such.  That requires some kind of menu control, and having done them before, don't really like writing that code even a little bit.

As to why I have the goldline at all.  It came with the pool.

Quick update on this:

we met a few pool vendors and we're about to pull the trigger. I decided to go ahead with my "sump" in the shed. I'll get a local steel fabricator to build it, and the pool installer agreed to help me in my project. I'm not getting a P4 and will only get the chlorinator since I'll be making the controller myself. I'm also gonna get a variable speed pump.

right now i'm struggling with my arduino on a few things. those being: ethernet module (enc28j60) being a real b*tch to work with. I'm gonna have to get a "real" w500 one I believe. I also received my phidget probe adapter and I tested them. They seems to work fine but until I get both my Ph and ORP probe there's no way to tell. I'm also having some difficulties with a relay boards I got which was suppose to turn on/off 110V electricity based on 12V input and 5v signal but I'm not sure why it is not working. I just received a few SSD relays that I'll try right after this post. Last problem in the queue is a set of LM35 I've ordered. out of 5, only 1 "seems" to work "ok". Shitty crap from china. I knew 3$ for 5 sensors out of ebay was too good to be true!!

nothing really relevant to anybody reading this post but just to let you know that i'm moving forward and that you should expect some nice pics of the building. I've started working on the enclosure, my water level code is done, if the SSD relay works tonight I should have the initial release ready to show you.

stay tune.

The 5100 has its own problems, but it is much easier to use and takes far less code space.  There's tons of examples out there on the web for this device so you should be fine with it.  As you go, make sure you can stand a board hanging up or rebooting unexpectedly.  Power failures happen and the arduino will hang up from time to time for no apparent reason.  The reason is almost certainly bad code, yours or something in a library somewhere, but you may never find it.  So, get familiar with the watchdog timer and resetting the time when you have to reboot.

I've played with three different temperature sensors now and the lm34 was the most accurate and easiest to use.  So, I'm surprised you are having trouble with the lm35.   Could be you're right about the quality, but everything I've gotten out of China has worked first try; lucky I guess.
