In order to the tag be able to download the historical data from eWON’s DataMailbox, the tag setup in the points must have historian enabled on it. Otherwise, the driver will not try to download the historical data.

| To avoid conflicts when saving historical values, it is recommended to disable the "save on change" and "save trigger" in the historical table configuration. Otherwise, it will store the values downloaded from the driver and the values generated by the value change and trigger. |
