Setting up multiple IotaWatts

I am installing two colocated IoTaWatts. One on a main panel and one on an adjacent direct fed sub-panel. I have three somewhat related questions:

  1. Can the two (or three) IoTaWatts share a single voltage reference transformer without causing problems? I.e. use a splitter cable.

  2. Can the IoTaWatts be powered from a single multi-port charger of sufficient capacity?

  3. I have an UPS nearby. Does powering the IoTaWatt monitors when the voltage reference goes away cause any problems?

Thanks again to this wonderful community.

I suggest The IoTaWatt forum is a better place to ask a question that is specifically about the operation and use of IoTaWatt. That is managed by Bob Lemaire, its creator, and he and the other users there are more likely to have the specific knowledge to help you.

The IoTaWatt forum uses the same software as this, but you must register a new account there. If the user name you have here is not taken, it might be helpful to have the same user name in both places.

If you post your question there, I’m sure he or somebody will get back to you quickly.
