+The __7M.24 energy meter__ communicates via the Modbus RTU on the RS-485 interface. The relay functions of Opta™ will control the relevant household appliances. To gather data and oversee power allocation, Opta™ carries out the following steps:
 
 - Procure voltage and current readings from the energy meter.
 - Gather three types of power readings from the energy meter: _Active Power Total - Pt (`W`)_, _Reactive Power Total - Qt (`var`)_, and _Apparent Power Total - St (`VA`)_.
 - Organize the collected data on Voltage, Current, and Power (Active, Reactive, and Apparent) into various categories to represent the _Actual_, _Average_, _Maximum_, and _Minimum_ values of each.
 - Access the Energy Counter figures in _`Wh`_ and _`varh`_ units.
 - Distribute power optimally to regulate selected household appliances based on the user's energy profile.
 
-While all these processes are handled by Opta™ locally, it is also connected to the Arduino Cloud through Wi-Fi®. This connection lets users view their energy usage and remotely control connected devices via the Arduino Cloud.
