Using write function

[GZPERRA]

First of all make sure that your model DERCtlAC (DER AC controls model, id=704) is available on your target device.
You can check that by printing the models dictionary print(d.models) and looking for two keys: 704 (model ID) and DERCtlAC (model name).

• If you didn't find any of those keys, then your device doesn't have this model.

• If you found the ID (704) but not the name, then you forgot to include the model definition file: model_704.json. Copy its content and put it here: sunspec2/models/json/model_704.json.

Now to change your value, it's recommended to do it this way (using the class Point):

# Enabling power factor when injecting active power.
d.DERCtlAC[0].PFWInjEna.value = 1 # The value has changed in the object
d.DERCtlAC[0].PFWInjEna.write() # The value has changed in the device

Hope it helps, although I'm late :/.
