Monitoring a sub panel?

[kevin1]

I have a second Sense that I use for two dedicated circuit monitors, because I’m in the same situation as you - already have solar and my main Sense is tapped out. Second Sense works just fine with the following caveats.

• Requires a second Sense account, so the results are not combined in the Sense app. I use Home Assistant to combine.
• My setup uses Flex Sensors on second Sense for DCM, with the primary set of CTs on the mains. There might have been a way to use the primary CTs to monitor a third 240V circuit, if the circuit has power flowing continuously.
• You might need to connect with Sense support because using for sub-panels, without seeing the solar feed-ins confused the Sense auto-setup.

Dedicated Circuit Monitoring (DCM) if you already have Sense Solar?

Several Sense Solar users, including @andy, have raised the question fo how they might take advantage of DCM, since their second monitor port is already occupied with solar monitoring. I have done a little experimenting and been able to test an approach for Solar users, by using a second Sense monitor for its DCM capacity. I currently have 2 x 240V devices monitored by my new Sense, a Tesla charger and sub panel for all my floor heating coils. A few caveats upfront: Pricey - you have to buy a…

ps: If you have a Square D/Wiser smart load center (breaker box), I think you can get the green Wiser version of the Sense monitor to meter all the smart breakers in the panel. Wiser Energy is the Wiser / Square D variant of the Sense energy monitor.
