Is anyone aware of any other OSHW alternatives to this? Preferably with Ethernet. ESPHome would be preferable.

The clones I can find are roughly the same price as the "original" hardware.

ATM90E32AS seems to be ~$1 per channel on JLCPCB, so I'd imagine this could be pretty cheap with SMT assembly. My use case is like ~60 circuits.



You can install esphome on Emporia Vue. https://github.com/emporia-vue-local/esphome (not used this myself). Vue V3 has wired ethernet support too.


The main one I'm away of is IotaWatt, which I've had running in my panel for the last few years without incident.


Eh, that's even more expensive. I think I'll end up having to develop my own hardware, even with Vue blowing $1500 for energy monitoring is a bit too much given how cheap the hardware can be.


for 60 circuits, you would need 4 units at 16 circuits each. which would be around $700 at current Amazon prices.


Many people flash the emporia vue with espHome
