hello energy gets energy & sustainability data from smart meters for electricity, gas, and water. This data is used to provide an energy monitoring system (EMS) and to visualize energy on screens. In order to enable digital reading, all meters in and around the building need to be smart and digital (no pulse). All generating systems (e.g. solar, wind) and charging stations (for electric transport) must have their own electricity meters. It is important these meters are equipped to send data with the right connectivity.

Data (& connectivity)

For all smart meters the following requirements apply:

✔️ All data supply is the responsibility of the metering company (for official main meters) or the installation company (for submeters). Both to be called “supplier”.

✔️ Availability: the data must be available at the latest the next day at 06:00 (local time).

✔️ Interval time: the data must be available at a fixed interval of 15 minutes.

✔️ Time stamp: the data must be validated and provided with a time signature in UTC (00:00:00 (hh/mm/ss).

✔️ Time signature: explanation whether the data relates to the period prior to or following the timestamp.

✔️ Unit and factor: the data’s unit and factor should be clear

✔️ Data type: it should be clear whether the provided data is a readout of the value at a certain point in time, or the value difference between two consequent timestamps.

✔️ Data format: value with 3 decimals.

✔️ Data validation: the data is checked for validity. The supplier will indicate how this will be realized.

✔️ Data labeling: to make sure the data is recognized correctly, data need to be labelled using a unique ID, consisting of: client, city, building id, source, location, unit. (Example: Prologis Tilburg DC5 Electricity, hal A, kWh -> “TBDC5ELhalAkWh”)

✔️ Transport: data can be included in the hello energy platform in four ways:

✔️ Push: database link (API), by which the data is pushed to the hello energy database to an URL defined by hello energy.

✔️ Pull: data link (API), in which the hello energy database retrieves the data from the database on a daily basis. This requires a secure login.

✔️ (s)FTP server: if required, hello energy can make available a FTP server location

✔️ Email: a daily email is sent including a .csv file (which fulfills the requirements mentioned above) to an email address provided by hello energy.
