Linux daemon to control Aqualink RS pool controllers. Provides web UI, MQTT client & HTTP API endpoints. Control your pool equiptment from any phone/tablet or computer. Is also compatible with most Home control systems including Apple HomeKit, Samsung, Alexa, Google, etc.
Binaries are supplied for Raspberry Pi, Has bean, and can be compiled for many different SBC's.

It does not, and will never provide any layer of security. NEVER directly expose the device running this software to the outside world; only indirectly through the use of Home Automation hub's or other security measures. e.g. VPNs.


If you like this project, you can buy me a cup of coffee :)

AqualinkD forum now open (Please use this for questions / issues / problems).

For Bugs, please use issues link on top of page.

Please see Wiki for installation instructions

For information on Control panel versions and upgrading the chips.

Here's where I started to document what I know about the Jandy RS485 protocol.

AqualinkD built in WEB Interface(s).

Default web interfaceSimple web interface
Both Interfaces
  • If loading the web page in a mobile device browser, you will need to save to desktop where an app will be created for you.
  • The order and options shown are configurable for your individual needs and/or preferences.
Default Interfaces
  • The layout and functionality are from the Apple HomeKit interface. This works in any browser or on any mobile device.
  • Customizable tile icons & background images. (Tiles not used can be hidden).
  • Thermostat, SWG & Light tiles have more options (ie: setting heater temperature, salt generating percentage and light mode etc). These options are accessible by pressing and holding the tile icon.
  • Supports live background images (ie: poll camera for still image every X seconds).
In web browser/tablet


Designed to mimic AqualinkRS6 All Button keypad and (like the keypad) is used to fully configure the master control panel

In Apple Home app.

  • (NOTE: Salt Water Generator is configured as a Thermostat. It is the closest homekit accessory type; so °=% and Cooling=Generating).
  • Full support for homekit scenes: ie: Create a "Spa scene" to: "turn spa on, set spa heater to X temperature and turn spa blower on", etc etc).

In Home Assistant

All Web interfaces.

ToDo (future release)

  • Allow selecting of pre-defined VSP programs
  • Timed based actions / programs (undecided on cron & AqualinkD or use Jandy programs )
  • One off timed actions (ir turn pump on for 2 hours)
  • Put back some form of Jandy panel simulator. (existing was removed in V2.2.0)
  • Add RS Serial protocol. AqualinkD has all Jandy control protocols except RS Serial.
  • Update homekit-aqualinkd to use new API & features.
  • Add light programming to Aqualink Touch protocol.

Update in Release 2.2.2

  • Fixed some Web UI bugs
  • Color lights now quicker when selecting existing comor mode.

Update in Release 2.2.1

  • Supports serial adapter protocol rssa_device_id, (provides instant heater setpoint changes & setpoint increment)
  • Can use seperate threads for network & RS485 interface. (optimisation for busy RS485 bus implimentations)
  • Display messages now posted to MQTT
  • Finilized all pre-repease work in 2.2.0(a,b,c)
  • Optimized the USB2RS485 Serial adapter logic.
  • Logging bitmasks to focus debugging information
  • Serial Logger changes to test for speed / errors & busy network bus
  • Changed raw RS485 device reading, to specific devices rather than all
    • Change read_all_devices & read_pentair_packets to read_RS485_swg, read_RS485_ePump, read_RS485_vsfPump
    • Since you can now target specific device, I've reverted back to displaying the real information of the device & not trying to hide it like the panel does. please see wiki config section for more details
  • Can link Spa Mode and Spa Heater (web UI only). add var link_spa_and_spa_heater = true; to config.js

Update in (Pre) Release 2.2.0c

  • Cleaned up Makefile (and adding debug timings).
  • Changed loggin infrastructure.
  • Added expermental options for Pi4.
  • 2.2.0a (had some issues with compiler optimisation), please don't use or compile yourself.
  • Fixed RS-4 panel bug.
  • Fixed some AqualinkTouch programming issues.
  • Increased timeout for startup probe.
  • This release WILL require you to make aqualinkd.conf changes. Make sure to read wiki section
  • Extensive work to reduce CPU cycles and unnesessary logic.
  • iAqualink Touch protocol supported for VSP & extended programming.
    • This protocol is a lot faster for programming, ID's are between 0x38 & 0x3B extended_device_id, use Serial_logger to find valid ID.
    • If your panel supports this it's strongly recomended to use it and also set extended_device_id_programming=yes
  • New panel config procedure VERY dependant on panel type, you must change config, must set panel_type in config.
    • Buttons (specifically) heaters will be different from previous versions. (all info in wiki link above)
  • Simulator support removed for the moment.
  • Few changes in RS protocol and timings.
  • Fixed bug with Watts display for VSP.
  • Fixed bug with colored lights.
  • RS16 panels no longer require extended_device_id to be set
  • More compile flags. See notes in wiki on compiling.
  • Extensive SWG logic changes.
  • AqualinkD startup changed to fix some 'systemctl restart' issues.
  • More detailed API replys.

Update in Release 2.1.0

  • Big update, lots of core changes, please read wiki section
  • Full Variable Speed Pump support. (Can read,set & change RPM,GPM)
  • Full support for all Colored Lights (even if Jandy Control Panel doesn't support them)
  • Chemlink pH & ORP now supported. (along with posting MQTT information)
  • There are some configuration changes, make sure to read wiki (link above)
  • RS12 & RS16 Panels now supported. (RS16 will also need extended_device_id set for full AUXB5-B8 support)
  • New UI option(s) turn_on_sensortiles = true & show_vsp_gpm=false in config.js
  • Added compile flags. If you make your own aqualinkd and have no need for PDA or RS16 support, edit the Makefile.
  • Completley new API.

Update in Release 1.3.9a

  • Improved Debugging for serial.
  • Added panel Timeout mode support to UI and MQTT
  • Fixed SWG bug while in Service & Timeout modes
  • Cleanded up SWG code and MQTT status messages for SWG and SWG/enabled
  • Fixed SWG bounce when changing SWG %

Update in Release 1.3.8

  • Fixed PDA mode from 1.3.7
  • Added SWG Boost to PDA
  • More updates to protocol code for Jandy and Pentair.

Update in Release 1.3.7

  • PDA Note:- Due to changes to speed up programming the control panel, PDA mode does not function correctly, I will come back and fix this, but I don't have the time for this release.
  • SWG updates
  • Simulator update
  • Added boost functionality for SWG. (Web UI & MQTT only, not Apple homekit yet)
    • MQTT boost status is aqualinkd/SWG/Boost
    • MQTT boost on/off is aqualinkd/SWG/Boost/set
    • Web UI, long press on SWG icon for boost & percent options
    • Simple Web Ui, extra button called Boost
  • Changed how programming works. (Please test fully things like, changing heater setpoints, SWG percent etc, be prepared to role back)
  • Added raw RS485 logging

Update in Release 1.3.6

  • Can now debug inline from a web ui. (http://aqualinkd.ip.address/debug.html)
  • Fix SWG in homekit sometimes displaying wrong value. Note to Homekit users, Upgrading to 1.3.5c (and above) will add an aditional SWG PPM tile, (look in default room). You'll need to update homebridge-aqualinkd to 0.0.8 (or later) to remove the old PPM tile (or delete you homebridge cache). This is due to a bug in homebridge-aqualinkd < 0.0.7 that didn't delete unused tiles.
  • Logic for SWG RS486 checksum_errors.
  • Fixed pentair packet logging, missing last byte.
  • Support for two programmable lights. (Note must update your aqualinkd.conf).
  • Can now display warnings and errors in the web UI (as well as log).

  • AqualinkD will now automaticaly find a usable ID if not specifically configured.
  • Support for reading (up to 4) Variable Speed Pump info and assigning per device. (Please see wiki for new config options).
    • At present only Pentair VSP is supported, if you have Jandy VSP (ePump) and are willing to do some testing, please post on forum as I'd like to get this supported as well.
    • For VSP you will need to check configuration for read_all_devices = yes & read_pentair_packets = yes and assign RS485 Pump ID to Device ID in configuration. serial_logger should find ID's for you.
    • WebUI will display Pump RPM only. RPM, Watts and GPH information is also available from MQTT & API.

Update in Release 1.3.2c
