The Sengled NB-7 (zigbee) has been a reliable choice for me, and are pretty darn cheap ($). I also use a couple Aeotec Smart Switch 7's (z-wave) for some power reporting - they work great, very reliable and are highly customizable, but oy, they are pricey.
But I've also had really good luck with the 2 Zen 15's I have, so I would've (otherwise) heartily recommended those too.
ETA -- INNR also makes a power-reporting plug (234 model), and it initially had bad firmware, but an available firmware update has supposedly fixed that (but I don't have any first-hand experience with those -- but I do use a lot of the 224-model INNR plugs and have been very happy with those, so I'd consider the 234 for any future needs)
These are all plug in devices. Since I am replacing the wall receptacle, I wanted to replace it with a smart receptacle that reports power from each outlet. Oh, and there are no neutrals.
weird i have 4 zen 15s and 3 are in basement and one in office for ac.. none have ever dropped out.. what does your routing to them at time of failure show..
I'm not aware of any in-wall smart outlet receptacle that has both outlets smart -- all I've ever seen with those is one smart outlet and one dumb outlet.
But no matter what you replace the Z15 with, make sure it can handle the power load of its respective appliance -- washers & dryers are appliances that can potentially draw more power than many smart devices are rated for, so check those numbers carefully.
I know it misses the mark on everything on your wish list, but a wifi Kasa plug would work great. The wifi has a lot more bandwidth for power reporting and there's a built in integration. Although for some reason the plugs aren't listed on the supported devices list... not sure what's up with that.
