I got curious, dug through my notes. > Zigbee SE is the official name for the standard. Good luck w/ your Utility Company. > Clamps would work, or the optical connection. But unsure if that's disabled. If the optical connection isn't disabled, I'd go that route. Clamps are a _pain_ if the space is cramped or the installer did a poor job of keeping things tidy. The upside to clamps is that you get per-circuit and in real time. If you have a dedicated circuit for big appliances, integrating the clamp into Home Assistant is a cheap way to get a "is the dishwasher done?" signal, for example.
