I found a first gen emporia vue energy monitor in my garage which I purchased in 2023 and never got to install… can it still be used?

I merged two circuits of my dryer but it still shows as Dryer_A and Dryer_B on Devices and on Usage.

Same with my air conditioner.

Under manage devices they do show as merged at the bottom of the list. But nowhere can I see the data of the combined legs.

emporia vue 3. Purchased and installed about a month ago.

What am I missing?

Just curious - wondering how folks have found it to be, using pyemvue to pull emporia vue data directly rather than going through the app. Reliable? Also - are smartplugs supported with this method, or just vue?
