Subscription Activate

In this article, you will create Robonomics parachain accounts and buy an IoT subscription.

To control Home Assistant with Robonomics, you need 2 accounts on the Robonomics parachain. For one of the accounts (OWNER), you will buy a Robonomics subscription. The second account (CONTROLLER) will control all Home Assistant processes (such as telemetry) and will give access to other users. These accounts will provide security for your Home Assistant.

If you don’t have an account, check this article and create the OWNER account. The Controller account will be created automatically during setup.

In the article, a Polkadot.js extension wallet is used for working with accounts, but you can use another wallet that is convenient for you.
