Pentair Intellitouch Plugin

OK. Thanks! I'm going to go with the Autelis system because it doesn't require you to sign in to "their" servers to get remote access. Call me paranoid, but I'd rather not have to rely on someone else for my pool control!

Guys,

After not hearing from the engineer since that one and only call, I called today and got him at his desk. He told me that he had broached the subject with Pentair about exposing their ScreenLogic 2 API to customers, but that Pentair considers that protocol proprietary and will not share that information.

Such a shame that I and others have spent considerable money on their products only to get this type of response. It's almost enough for me to go reverse engineer the protocol and create a domain name to give away the secrets of the protocol.

Couldn't much blame the engineer. He carried the water bucket, so to speak, and that's the answer he received. I guess it's time to make calls to other folks there.

any chance we can reverse engineer it from their app?

I too am interested in reverse engineering it. I've done a ton of research on this online. I've bought an RS 485 ->232 adapter + wifi adapter, and am telnetted into the system. It is spitting back ???'s in text:

Code: Select all

[~] tornado% telnet 10.0.1.222 5000
Trying 10.0.1.222...
Connected to 10.0.1.222.

???????~~???????????~??


switching to Hex I'm getting:

Code: Select all

[~] tornado% telnet
telnet> set termdata
Will print hexadecimal representation of terminal traffic.

I've hit the following sites but am hitting somewhat of a wall as the codes I'm receiving are not consistent with what these other folks have dug up:

I'm hopeful the collective nerd brain on here (myself included) can possibly crack this so we don't have to resort to $270 Autelis (http://www.autelis.com/pool-control-for-pentair-intellitouch-easytouch.html) or $600+Pentair converters (http://www.poolsupplyworld.com/Pentair-520442-i-Link-Home-Automation-Adapter-Interface-for-IntelliTouch/520442.htm) to get it to work with Indigo.

Hopefully some of you can pile on here! Happy New Year!

P.S. Boisy - love your MacTech articles!

tornado:

I am happy to help but would need alittle help to provide whatever information you need. I am connected only thru the screenlogic adapter. I do not have a 485-RS232 connection setup.
Just let me know what you need from me.

Thanks!

When you say you're connected thru the screenlogic adaptor - are you talking about the iLink device or the newer one that has a proprietary protocol?

Thanks,
Joe

The new screenlogic2

Yeah I have that one too - but I can't decipher that protocol either.... I don't think anyone has figured it out yet based on my Googling but I'm hoping I'm wrong.

I don't see that pattern in my output unfortunately. I wonder if it was changed by Pentair?

Using the plugin with Pentair's RS232 Serial interface; is there a list of the items you can control and how they can be controlled (example: intelliflo pump 0-100% or Heating: 80-106 degrees)?

Pentair's serial protocol is published online. There's no provision to change the pump speed, but you can change the temp set points.

Serial protocol is linked in 4th post of this thread.

Yes I read the protocol in the guide. I was hoping I was missing something. I wonder why they offer heat but not pump speed control? Does anyone know of a way to use indigo and control pump speed.

I have an Intellitouch system, but only a single speed pump. How do you control the pump manually? Is it a button on the keypad? I wonder if the panel can be wired such that an aux relay would control the speed. Like off=low and on=high. Then you could control it from Indigo.

As far as I can tell, you can't even control the pump speed directly with the intelliflow handset. You can do it directly from the panel on the pump though.

I wonder if you can set up a custom pump speed and save it as an auxiliary circuit or something. If you could, then that could be activated with Indigo.
