Change climate temperature

Hi! Im trying to change the setpoint of my heater with node red.
I can change within the integration in HA, but not in node red.
See pictures below:

I can send turn_on and turn_off. But when I try to change temerature I get an API error.
tried both set_temperature and set:aux_heat.

Any ideas??

Sorry, I suspect that this is more about HA than Node-RED. You may be better off asking in their forum as most people here don't bother with HA.
