Remote climate control doesn't make too much sense on self-charging hybrids.
AC would not be unworkable as AC doesn't need anything but electricity from battery. But heating is not an option as it's provided by ICE. Heating the car is faster when driving and I would see it as highly not-eco to run the car while parked. It would not align with push for eco.
Yes, a pure electric or a plug-in hybrid car would have a heat pump that runs only on electricity. So in that case it make total sense! Think about turning on heat pump or AC while plugged in the charger. So one would not use any electricity from the battery.
But in case of a self charging car, none makes sense!
Think about a normal car parked in the sun. Temperature in the car will be way higher than outside. So it makes total sense to open the doors for a couple of minutes to "cool" it down, before turning on the engine so AC will start operating.
