Providing Metering Data

At Otark you can upload metering data to metering points and assign them to your assets & demands. The metering data is then shown on the asset/demand detail page (after getting access) and allows prospects and yourself to view & compare the data to see if an asset or demand would be a good fit. To get the load data into Otark we currently support a manual CSV upload in the Otark admin.

General Requirements

One smart meter per file: Each CSV file can only contain data for one smart meter. Uploading data for multiple smart meters via one file is not supported at this time. If this is a requirement please get in touch with us.
Each row must represent a 15‑minute measurement interval.
The first row in the file must be a header row containing the column field names.
Field separator: Semicolon (;).
Character encoding: Automatically detected (use UTF‑8 if unsure).
