It can be used by anyone, regardless of whether they are IAMMETER-cloud users.

EFSS & IAMMETER

EFSS currently offers two main functionalities:

  1. It calculates the actual electricity bill based on the customer's real electricity consumption and feedback, helping to identify the most cost-effective electricity tariff.
  2. It analyzes the benefits and return on investment (ROI) of introducing an energy storage system based on the customer's actual electricity usage data.

Please note that you can use EFSS regardless of whether you are an IAMMETER user. The only difference is that IAMMETER users can directly import the hourly kWh data (from grid, to grid, yield) required by EFSS. Non-IAMMETER users need to prepare this data themselves and upload it to EFSS according to the CSV file format.

For instructions on how to use EFSS, please refer to the EFSS User Manual.

For any questions about using EFSS, you can communicate directly with us through our official forum.

Let IAMMETER Help You Save Money

IAMMETER provides a comprehensive set of energy monitoring and management hardware and systems that help customers better understand their electricity usage and avoid unnecessary energy waste.

Moreover, IAMMETER is committed to offering specific methods for users to gain more benefits from monitoring their energy usage. This is the concept we advocate: "Monitoring is just a means; saving money is the goal."

With IAMMETER, you can control your electric vehicle charging and your boiler heating. If you have a photovoltaic system, you can set IAMMETER to charge your vehicle or heat your boiler using only solar surplus, thereby maximizing the self-consumption rate of your photovoltaic system.
