     * and Comfort Cloud app only set the target temperature.
     *
     * Option 1: Don't map the AUTO setting in HomeKit to AUTO on ComfortCloud (CC),
     * but switch to COOL or HEAT on CC depending on the current room temperature.
     * In that case, we could process the heating and cooling threshold accordingly.
     * Caveat: HomeKit set to AUTO would show up as HEAT or COOL in the CC app, i.e.
     * we would produce an inconsistent state across control interfaces.
     *
     * Option 2: Map AUTO in HomeKit to AUTO on CC and set the temperature which was set last
     * as target temperature. The user would have to drag both sliders close to each other
     * and treat it as one bar.
     * Caveat: We cannot replace a range slider in HomeKit by a single value. Any user
     * who doesn't read this note might be confused about this.
     *
     * Current choice is option 2 because the only implication for the user is wrongly set
     * temperature in the worst case. Option 1 would offer full functionality, but decrease
     * the compatibility with the Comfort Cloud app.
