Control Jandy Aqualink via a web interface from anywhere in the world

• USE AT YOUR OWN RISK
• DO NOT PUT YOUR POOL ON THE PUBLIC INTERNET.
• DO NOT NAT PORT-FORWARD FROM YOUR ROUTER TO THE CONTROLLER.
• DO NOT PUT THIS ON AN UNSECURED WIFI NETWORK.
• THIS MAY VOID YOUR POOL WARRANTY
• I AM NOT ASSOCIATED WITH JANDY OR RELATED COMPANIES

This Python script allows control of Jandy Aqualink pools with remotes via a web interface.

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.

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

• LCD Controller: http://raspi/
• SpaLink: http://raspi/spalink.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
