Pool-Pi
Pool-Pi is a hardware+software system for interfacing with Goldline/Hayward Aqualogic pool control boards over WiFi via a Raspberry Pi. It adds wireless capabilities to non-wireless control boards and a web interface for viewing updates and sending commands.
Demo Video
This video shows multiple clients interfacing with the unit and demonstrates display updates, button presses, menu controls, blinking display characters, and LED updates.
Overview
Pool-Pi provides a web interface which emulates a local PS-8 display, allowing for the same controls accessible from the physical unit. The serial bus exposes all 14 aux relays regardless of local display, so emulation of a PS-16 display is possible, allowing additional relays to be added without purchasing a larger local interface. An RS485 adapter is used to read and send messages in accordance with the Aqualogic serial communication protocol, mimicking an OEM device. The system also adds logging, which is unavailable on the OEM unit. A simplified GUI is available to show the most frequently used commands.
Setup
Project requirements and instructions can be found in docs/SETUP.md.

Questions
How big is the Pool pi v1.1 PCB?
It measures 65 × 56.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pool pi v1.1 use?
28 parts, built around the MAX485ED, LM2596S-5.0 and DMG2305UX-13. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Pool pi v1.1 KiCad files?
From the ChaseDurand/Pool-Pi repository on GitHub, at the commit this page was made from: the board is docs/pcb/pool_pi_v1.1.kicad_pcb and its schematic docs/pcb/pool_pi_v1.1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pool pi v1.1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask ChaseDurand before reusing the design.
