Please replace the following code (thermostat_card.lib.js)try, and feedback. Remember to clean up your browser cache after changes Thank you for your work.

  _updateColor(state, preset_mode) {

    if(Object.prototype.toString.call(preset_mode) === "[object String]"){

      if(state != 'off' && preset_mode.toLowerCase() == 'idle')
      state = 'idle'

      this._root.classList.forEach(c => {
        if (c.indexOf('dial--state--') != -1)
          this._root.classList.remove(c);
      });
      this._root.classList.add('dial--state--' + state);
    }
  }
