When is a boolean not a boolean???

[Si67]

I am having an issue that has me stuck.

I have a script which checks a group of thermostats, if any call for heat the scrip generates a boolean to a GA.

The script works and the change to the GA shows in the logs and bus monitor etc.

The problem is that this boolean does not switch the actuator.

The weird thing is that from ETS a GA write changes the boolean and the actuator changes state.

Equally using the set value from the wiser for knx objects tab changes the GA boolean and the actuator changes state.

So why is it that a boolean generated from a script which switches a GA boolean is incapable of changing an actuator state???

Hi Si67,

hmm, something seems to be wrong.
Can you share more informations like pictures, the script, your architecture etc. please?

You probably use grp.update in your script, this will write the value on IP (that is why you see it in the monitor) but not on the TP (due to the limited bandwidth on TP) so the actuator will not receive anything, change grp.update to grp.write
