I am glad it worked for you
The next step will be to include the driver in Hubitat Package Manager (HPM), so that the driver updates can be applied much more conveniently and quickly.
The reason for the repetitive 'amperage ' values shown on the device page was a bug (a trailing space in the name),
Next in my TODO list is to optimize the polling process. What is important and is most often used in HE automation rules/apps is the power value, which must be updated quickly enough. The voltage is (or at least should be ) relatively constant. The amperage depends on the measured power, so if the power measured doesn't change (or changes less than 5% for example), there is no need to read the amperage and the voltage again... Same for the energy, that has mostly statistical value.
These optimizations are needed because if you have a lot of outlets of this type that need polling, they could impact the Zigbee network performance... Polling such devices too often and for too many different parameters should be avoided, when possible.
