In order to get an Hayward Aquarite integration in Home Assistant with Tasmota we’ll go through several steps including wiring the ESP32 to the Aquarite and then the Home Assistant configuration.

Hardware : ESP32

Step 1 : Prototype

We’ll use :
– ESP32 from AZ-Delivery
– RS485 to TTL adapter

The wiring will be done as follow :

Step 2 : Final version

For the final version, we’ll use an M5stack ESP32 with a RS485 tail, in order to have a clean, small and 10v powered device.

Software : Tasmota

With the “Sugar Valley NeoPool module” Tasmota support natively this salt chlorinator.
This option is not compile in the standard version, we’ll need to compile Tasmota in order to compile this functionality.

#ifndef USE_NEOPOOL
#define USE_NEOPOOL

Then compile and upload :

platformio run -e tasmota32 --target upload --upload-port /dev/ttyUSB0
