AqualinkD MQTT to control the pool

Tutorials & Examples Solutions
, ,

I see there is a pentair pool binding but I have an older pool controller with a PDA. I’ve been using AqualinkD for years and it works great. I’m new to openHAB and I’m trying to use the MQTT binding to control AqualinkD, There is information on the AqualinkD wiki for MQTT and instructions to set it up with homekit. Has anyone else connected AqualinkD to openHAB? Any advice? Is there a way to import the homekit2mqtt.json into openHAB?

There is no way to import a JOSN file for Homekit into openHAB. openHAB is not Homekit.

But that wiki page documents all the MQTT topics and the type of data that is publishes or expected on each one. So you’ll create a Generic MQTT Thing and set up a Channel for each topic you care about. Then you’ll link Items to those Channels and the rest of OH will interact with the Items.

See Adding Things - Advanced | openHAB for a brief example for creating a Generic MQTT Thing and Channels.

MQTT is a one of the lower level bindings. You have to do most of the set up by hand which makes it harder to use. But it makes it much more flexible and able to handle odd situations and cases where people use MQTT in odd ways.

A great tool to help building your Channels is MQTT Explorer (https://mqtt-explorer.com/).

There you see what’s going on and the actual topics and states. Then you can transfer them into the openhab configuration.
