A custom Lovelace card based on the native thermostat card that allows to control dual thermostats that create separate Heat and Cool entities.

Heat and Cool entities are updated depending on the active thermostat mode. The low point on the Auto mode controls the heat entity and the high point controls the cool entity allowing you to use a single card for both entities.

1. Download the repo as a zip or with git clone and copy contents of the /dist folder to the /www/dual-thermostat in your configuration folder.
2. Configure Lovelace to load the card:
