Introduction
To register a new user, you need a registration code. You can generate it yourself at: https://feili.omniai.org/admin.
With the registration code, you can generate a new account at https://feili.omniai.org and then login with this new account.
For a new account, the contents should be empty. There should be some mobile machine that you can buy and add to your account. But here you cannot buy it because they are only for development currently.
What you can do is use the REST API to add a new sensor and then verify that sensor. When the sensor is registered, you can add some data to that sensor.
This process can be run with postman:
You can download the APIs from here, and then import this file to your postman account.
