This Python script allows control of Jandy Aqualink pools with remotes via a web interface. Your existing setup needs to already have the new-style PDA, old-style square remote or SpaLink installed.

You will need a USB RS485 interface, a Raspberry Pi, and either a wireless or wired connection to your home network.

It emulates a LCD controller and a SpaLink control panel on the web interface as well as the RS485 bus.

Usage

With no parameters specified on the command line, it will attempt to use /dev/ttyUSB0 and run an auto-detect routine to see what controllers it can simulate. To manually specify which control models, or change the RS485 interface device, the following options are available:

  -h, --help            show this help message and exit
  --device DEVICE, -d DEVICE
                        RS485 device, default=dev/ttyUSB0
  --spalink, -s         Enable a SPALINK emulator at http://localhost/spa.html
  --pda, -p             Enable a PDA emulator at http://localhost/
  --aqualink, -a        Enable a AQUALINK emulator at http://localhost/

Install and run it from /etc/local.rc on a RaspberryPi and go to:

LCD Controller: http://raspi/
SpaLink: http://raspi/spa.html (where raspi is replaced with your RaspberryPi's IP or hostname)

There is no authentication, so anyone with access to your network has unrestricted access.

Some of the RS485 protocol routine was borrowed from https://github.com/ericbuehl/pyaqualink and some code on the excellent Trouble Free Pool forums: http://www.troublefreepool.com/threads/27391-Control-your-Jandy-equipment-from-your-PC-with-a-15-adapter The PDA style codes were uncovered by @johnnytaco.
