Is there an update on this issue?
I noticed that on the FAQ page it says:
Do I need to install the 200A Main sensors for the 50A sensors to work?
No, the 200A Main clamps for the Vue are not necessary for the individual circuit sensors to work and the 200A sensors can be used to monitor another circuit.
In my case, I want to use the 50A sensors to monitor individual circuits and the 200A sensors to monitor a circuit that goes to a subpanel.
