foXaCe/Fluidra-pool — reverse-engineered prompt

Build me a Home Assistant custom integration for Fluidra Connect pool equipment. I want to log in with my Fluidra account from the Home Assistant UI, including MFA codes if needed, then have it automatically find my pools and devices from the Fluidra cloud.

It should create normal Home Assistant controls for common pool gear like variable speed pumps, heat pumps, salt chlorinators, water analysers, heaters, and LumiPlus style pool lights. I want switches, sensors, climate controls, numbers, selects, lights, and schedule editing where the device supports it, so I can control pump speed, target temperature, chlorination level, pH and ORP setpoints, light colour, brightness, effects, and daily schedules.

Please make it HACS friendly, configurable from the UI, with a polling interval option, token refresh, re authentication when credentials expire, useful diagnostics with secrets hidden, and clear error messages. Add English plus French, Spanish, and Portuguese text if possible. Look up current Home Assistant integration docs online if you need to.
