In the Keygenerator Platform the encryption keys for the wMBus modules RFM-TX1, IWM-TX3, IWM-TX4 and for the Hydrosplit-M3 devices aren't available, wich is why the only way to obtain them is during configuration via BMetering Software or BMetering NFC Config (except for the TX1 modules wich keys are only available via BMetering Software).
The procedure to export the keys via NFC App is as follows:
- Open the BMetering NFC Config App
-
In the home page, enter the settings by opening the gear icon on the top right:
-
From this page it will be possible to view and/or edit the global encryption key, which can be put in the meters during configuration. Insert the key in the box and press the "Save" button
-
It will also be possible to export the key of already configured modules by pressing on the share icon
- From here, it will be possible to choose where to download the .Keys file, which will have to be imported on the BMetering Software
To export the keys from the BMetering Software instead, do as follows:
- Open the BMetering Software
- Without moving from the registry page press "Export keys" to obtain the .Keys file (the file that will later be used to import the keys) or "Export keys to CSV" to have them in a .CSV file
To import the file in the BMetering Software or the Hydrolink APP, view the following manual: IMPORTING WM-BUS KEYS IN THE BMETERING SOFTWARE
