Note the protocol is a binary protocol (not ASCII text based) and in order to view the communication packets, one must use a program capable of a binary/HEX mode.

Once you have the interface connected to your system, it is best to test basic connectivity. To use a symbolically linked device, add the following line to /etc/default/openhab EXTRA_JAVA_OPTS='-Dgnu.io.rxtx.SerialPorts=/dev/ttyRS485' Note: If you are on a Linux system, the framework may not see a symbolically linked device (i.e. Note: This is the setup utlized for the majority of my testing of this binding. If your openHAB system is physically located far from your Pentair equipment or indoor control panel, you can use a Raspberry Pi or other computer to redirect USB/serial port traffic over the internet using a program called ser2sock (see Reference section).Īn example setup would run the following command: 'ser2sock -p 10000 -s /dev/ttyUSB1 -b 9600 -d'. The binding includes 2 different bridge Things depending on which type of interface you use, serial_bridge or ip_bridge. # Connecting adapter to your systemĪ USB or serial RS-485 interface or IP based interface can be used to interface to the Pentair system bus. I have cited several of those in the References section below. Pentair does not publish any information on the protocol so this binding was developed using the great reverse-engineering efforts of others made available on the internet. It is a standard RS-485 bus running at 9600,8N1 so any RS-485 adapter should work and you should be able to buy one for under $30. This bus/wire runs between the Pentair control system, indoor control panels, IntelliFlo pumps, etc. This binding requires an adapter to interface to the Pentair system bus. IF YOU DECIDE TO USE THIS BINDING TO INTERFACE TO A PENTAIR CONTROLLER, THE AUTHOR(S) CAN NOT BE HELD RESPONSIBLE.

IT IS NOT ENDORSED BY PENTAIR AND COULD VOID WARRENTY. REQUISITE DISCLAIMER: CONNECTING 3RD PARTY DEVICES TO THE PENTAIR SYSTEM BUS COULD CAUSE SERIOUS DAMAGE TO THE SYSTEM SHOULD SOMETHING MALFUNCTION.

The binding was developed and tested on a system with a Pentair EasyTouch controller, but should operate with other Pentair systems. It is based on combined efforts of many on the internet in reverse-engineering the proprietary Pentair protocol (see References section).

This is an openHAB binding for a Pentair Pool System.
