Sign in with the Realer account that holds the control device's subscription. If you use or manage the resource, or own the device, but another account holds the subscription, ask that account's holder to manage it.
If the subscription belongs to you but you cannot find it through these paths, contact us.
If you are developing a new control device, register as a developer and follow the API-key guide to choose a plan. This requirement does not apply to managing or renewing an existing subscription billed to your account.
Subscriptions are monthly or yearly, per control device. Prices exclude tax; checkout shows the total including applicable tax before payment.
