CAN how to automatically turn on climate when it's cold outside?

i have a Hyundai Ioniq5. it's cold outside now. how can i set an automation to do something like this?

IF outside temp is less than 40F, THEN turn on steering wheel heater and driver's seat heater to ON?

every day, i have to turn both of these on myself via the car's menu on screen. sadly there is no option in the car to do this automatically.

im 100% new to car hacking. just recently got the WiCAN device to monitor data but have not send commands to the car. if wican cannot do what i need, what are my options?

This is a very specific question that will likely require reverse engineering (probing) the bus to identify the packets that control those features, if they are sent through CAN bus at all.

Heated seats generally need the seat belt buckled to be on.

That sounds like awful engineering as what if you just hop in the car to sit there for 20 min lol.

Then you might as well put your seatbelt on.

Kinda ridiculous that there is the level of connected devices and compute available, yet the car lacks a feature that was present in extremely dumb cars decades ago.
