Shelly driver input monitoring?

I'm using the custom Shelly Plus driver by Scott Grayban. It works great. However It only controls the Shelly output... has anyone found a way to monitor the input of a Shelly Plus 1?

Try alternative driver in the same thread. It is not tested on Shelly Plus 1, but on Shelly Plus i4 and Shelly Pro 2PM. Should scale automatically.
