What We Do

The overall system is a typical IoT system where the sensors gather data and send it to the server in the cloud that visualizes energy consumed and produced, sets a price for energy, sends this price back to the end devices, and keeps track of energy bought and sold.

 


Physical layer

The sensors are the first step of the IoT system and gather all the data that is later used by the server. In this case that is the electricity consumed and produced, as well as battery levels. The sensors are part of the charge controller that can communicate with the server via the communication layer.

 

 

Network Layer

The network layer depends on the project. Wattero uses one of the following options:
Cellular data or LoRaWAN.

LoRaWAN is a way of sending data using radio frequencies.

Regardless of option, the data ends up in a database in the cloud.

 

Application layer

From the database, the data can be accessed by both the dashboard and the backend algorithm. The dashboard consists of a user access management system and a user-friendly display of the data, including the consumption data and calculated price. It has preset ways to visualize the data in a simple manner. The dashboard also generates reports and gives alerts.

The algorithm continually sets a price for the energy that is sent to each end device and is used to calculate the balance of payments for each household each month. The price varies throughout the day and depends on the supply and demand of electricity in the grid.

Benefits 

  • Optimise the use of each solar panel in a microgrid
  • Optimise use of energy storage 
  • Increase the overall availability of electricity in the grid
  • Create a recurring revenue by charging a fee on each trade
