About

Atlantic Cozytouch connects Atlantic Cozytouch heating, cooling and hot water devices to Home Assistant through the vendor's cloud. It is installed as a custom repository in the Marketplace and set up in the UI with a Cozytouch username and password. It adds climate entities for rooms, air conditioners, central heating and heat pump zones, plus calendars for heating, cooling and hot water programs. Switches cover modes such as away, boost, eco, quiet and domestic hot water, and number and select entities handle target temperatures, override times and air circulation speed. Actions turn away mode on or off, and read a week's program or set a day program. Device triggers fire when a program changes or is overridden, and options set the refresh interval in seconds and whether to dump received data to a JSON file.
