What I'm trying right now is to get the "Zone Air Temperature" for "Thermal Zone 1" and the "System Node Temperature" of my "Setpoint Node".

zone_air_temperature = api.exchange.get_variable_handle(state, u"ZONE AIR TEMPERATURE", u"Thermal Zone 1")

setpoint_node_temperature = api.exchange.get_variable_handle(state, u"SYSTEM NODE TEMPERATURE", u"SETPOINT NODE")

If i call api.exchange.get_variable_value on them it always returns 0. Am I doing this wrong?

Thanks in advance.
