Setpoint temperature Z-TRM2, LUA command (HC2)

[knuth 29]

I am writing a scene which needs to set the setpoint temperature of my Z-TRM2 thermostats using a LUA command in HC2. I plan to address each thermostat individually, not through heating panels. 

The current value is succesfully retrieved by this command:

where id is the id for the setpoint sub-device of the thermostat. This works as expected.

 

However, when I try to change the setpoint through this command:

nothing happens, as shown by a subsequent getValue call. There is no error message, but the setpoint remains unchanged. I have tried to use the numeral 18 in stead of a string, and I have also tried with a variable name.What am I doing wrong in my fibaro:call command? The syntax is taken from the LUA API documentation, where this example is given:

Is the required command for the Z-TRM2 module different?

To supplement my question above: Seeing that there are 3 actions listed for this device ("Reconfigure", "SetSetpointMode", and "SetThermostatSetpoint") I have now tried this command:

but the result is the same: no change.

I found the solution by making a block scene and converting it to LUA. This is the correct call:

The "1" missing from my first attempts evidently indicates that this is a heating set point. 

 

Problem solved!
