Makers connecting their own heating or cooling equipment gain a standard climate interface in ESPHome. The new template component forwards commands from Home Assistant to custom actions, so a temperature setting or fan change can reach hardware through the connection a project already uses.
The component can take temperature and humidity readings from existing sensors and show the equipment’s reported state. Makers can choose whether controls update immediately or wait for confirmation from the device; an unavailable sensor clears its reading instead of leaving an old value on display.
Ricardo Sanz contributes both the component and its guide—his first contributions to ESPHome’s code and documentation repositories. Reviewers j9brown and ssieb helped check the work, with ssieb approving it.
