Intex Salt-Water Chlorine Generators (SWG) — Home Assistant Integration

Connect an Intex ECO 6220 / CG-26670 / QS500 Salt-Water Chlorine Generator to Home Assistant over a fully local REST API.

Prerequisite Hardware

The generator lacks built-in networking.
Install an custom ESP32 board flashed with the firmware from https://github.com/NemoN/intex-swg-iot and place it between the SWG display panel and the main board. The ESP32 serves JSON on port 8080 - this integration talks to that API.

Features

Category	Description
Telemetry	shows diplays status, uptime, free heap
Status / Alarms	boost, sleep, ozone generation, low-flow, low/high salt, service, working, programming, display on/off
Control	Power ON / OFF / STANDBY buttons
Watch-dog	optional scheduled reboot every n minutes (default 720 min)
Power sensor	map any existing wattage sensor into the SWG device card
Local-only	iot_class: local_polling — no cloud involved

Installation (HACS)

1. In HACS → Integrations → ⋯ Custom repositories add https://github.com/NemoN/ha-intex-swg as type Integration
2. Install “Intex Salt Water Chlorine Generators (SWG)” from the list.
3. Restart Home Assistant.

OR

Restart your instance and head over to the integration overview (Or use this link to directly go to the configuration of this component) to start configuring the integration.

Configuration

Modify settings any time under Settings → Devices & Services → Intex SWG → ⋯ Configure.

Option	Default	Purpose
Host	—	IP address of the ESP32 board
Port	8080	REST API port
Scan interval	30 s	Polling period
Enable auto-reboot	false	Toggle the watch-dog
Reboot every	720 min	Minutes between reboots
Power entity	—	Home Assistant sensor providing watts

Entities per Generator

• Sensors: display_brightness, display_code, uptime, free_heap, power (optional)
• Binary sensors: display_on, boost_mode, sleep_mode, o3_generation, low_flow, low_salt, high_salt, service_alarm, working, programming
• Buttons: reboot_esp32, power_on, power_off, power_standby
