This thread is meant to share information related to the emerging field of smart appliances and their coordination. 'SMART' can mean different things to different people, and consumers have different devices and different priorities. E.g., one person may be focused on keeping their home energy flowing during a grid outage. Another person may be focused on storage arbitrage. My interest is in maximizing home PV generation for highest efficiency and least output to the grid. The common ground (hah!) is appliances have to modify their own supply dependent in part on what every other appliance is doing, the state of home generation now and for the next day, and environmental conditions of the home and outside.

Sales 'smart breakers.' Each breaker is a wi-fi device that can turn the breaker on/off via phone app control. The app

• Has scheduling options at the breaker level
• Cannot island the PV generation from the grid
• Cannot be used to set up an off-grid profile

Span
Is IIRC a spin-off from Tesla. An entirely new panel replaces the one in place to offer both breaker level control and grid control. Control is via user preference using an app and allows

• On/off and scheduling at the breaker level
• Islanding of home generation to continue when the grid is down
• The user to designate an off-grid profile that takes both PV and battery into account

Legrand (NetAtmo)
As of 2/2021, only available in Italy and France. In addition to wi-fi controllable breakers, this vendor has an open API and supports the other leading home comm protocols from Apple, Google, and Amazon and IFTTT. It is on the dev track I hope to see advance.
