Error when getting data from HEM into RM

I’ve started getting an odd error when loading data from my Aeotec Gen 5 Home Energy Monitor (HEM) into RM.

I am using the following driver for the HEM:

In RM, some of the data that I am trying to load is shown as “?”:

However, we can see that the device does display this Energy and Cost data:

Device Events

The following are the logs that are generated from the rule above: (The warning can be ignored as it is from something else and I forget to filter before taking the screenshot)

If I try to instead use a Sensor Value, I get an error as soon as I select the device from the “Energy meter” selection box (in the existing or in a new rule):

I’m at a loss as to why this Rule has stopped working. It has worked for me for at least a year (triggers every 30 minute) without fail. Suddenly however, it has stopped working.

I have tried a soft reset and restoring a backup from yesterday, but the problem persists. I am at a loss as to what to do next to try to resolve this… Will get back at it tomorrow, but would love to get input/recommendations…

Changing the driver to another one available from HPM seems to have resolved the issue.
