unreadable 'data' output from node

[cdevereu]

Both my Tuya devices update their status to the node output automatically but the data is not human readable. It looks like this:

{"data":"3.3\u0000\u0000\u0000\u0000\u0000\u0000I�\u0000\u0000\u0000\u0001��Y#����\u0014�?��\u0013�-�/�\u00048���[�Q�d��","deviceId":"bf5aaa50aff2a5d15cirx9","deviceName":"Oil Tank"}

The deviceName and deviceId are fine.

Any ideas why the 'data' value is not in plain text?

OK I've been reading up more from other people with similar issues and by changing the version from 3.1 to 3.3 the payload.data became readable.

{data: "3.3�
[�?�,�r�U�e�?�)���x�Pt(��_o�����.�O#���Irj�tu}���e�d�" deviceId: "bf72b73d01c0d0cdfbyh6j" deviceName: "Smart Meter "}

I changed "Tuya Protocol Version, Default : 3.1 (don't change if you are not sure)" to version 3.3 but it didn't help please advise
