System and method to monitor and control pool equipment

A system for monitoring and controlling a multi-node pool equipment network, comprising:

• a main control unit configured as a master node to support a serial communication protocol across a plurality of nodes;
• and
• a first relay node connected to the main control unit by a serial interface configured for power and data transmission between the master node and the first relay node;
• a cloud server configured to:
• implement one or more machine learning algorithms to automatically minimize the carbon footprint of the system by scheduling operation of the connected pool equipment during a low carbon phase of a local power grid;
• connect to one or more power grid API services to retrieve carbon emission rates to the local power grid and identify one or more low carbon phases of the local power grid;
• wherein the main control unit is configured to send a command or a query to the first relay node over the serial interface using the serial communication protocol;
• and
• wherein the first relay node is configured to:
• switch a relay or a load connected to the first relay node;
• report a status of connected pool equipment to the main control unit;
• and
• report a measurement of the output of the connected pool equipment to the main control unit.
