Here's one more vote for buying a second one. I have two Refoss EM16P's, to monitor my 21 circuits. Started with one to monitor 16, but I hated having the "untracked usage" gray blob on the usage chart, so I finally gave in and installed the second one. I justified it by saying that if I add a new circuit down the road, it'll be really easy to throw on another plug around the wires and I won't have to buy anything extra to start monitoring it. I've been super happy with how well the EM16P's work with Home Assistant. Admittedly, I bought them when they were on sale - each was $159.99, but it looks like they just went up a bit literally this morning (so maybe there's another coupon coming soon?
