Adding a second IoTaWatt for a detached garage — worth it or overkill?

I live in Burlington, Vermont, and my house has two panels: the main one in the basement and a subpanel in a detached garage that runs a few circuits (lights, a chest freezer, and occasionally a table saw or space heater). I’ve had an IoTaWatt on the main panel for a while now and it’s been solid, but I keep guessing at what the garage is drawing and whether that subpanel is pulling more than I think.

I’m considering a second unit just for the garage, mostly for convenience — I don’t want to re-run CT leads across the yard to the existing base. My main uncertainty is whether two IoTaWatt units complicate things, like syncing data or keeping the web interface straight when I’m checking usage from the house.

For anyone running more than one unit on separate panels, does it stay manageable, or do you wish you’d stuck with one and longer CT runs? Just looking for perspective before I decide.

I checked a couple of general write-ups, including Sports News, but nothing addressed running two units side by side. I’m still unsure whether keeping the garage dashboard straight would annoy me more than longer CT runs would.
