How to manage things with the registry

  • Note
    We don't recommend using personally identifiable information in your thing names.

Thing types

  • Note
    You must wait five minutes after you deprecate a thing type before you can delete it.

Static thing groups

  • Note
    We don't recommend using personally identifiable information in your thing group names.
  • Important
    Keep in mind the following limits when creating thing group hierarchies:
    A thing group can have only one direct parent. The number of direct child groups a thing group can have is limited. The maximum depth of a group hierarchy is limited. The number of attributes a thing group can have is limited. (Attributes are name-value pairs you can use to store information about a group.) The lengths of each attribute name and each value are also limited.
  • Important
    You can add a thing to a maximum of 10 groups. But you can't add a thing to more than one group in the same hierarchy. (In other words, you can't add a thing to two groups which share a common parent.)
    If a thing belongs to as many thing groups as possible, and one or more of those groups is a dynamic thing group, you can use the https://docs.aws.amazon.com/iot/latest/apireference/API_AddThingToThingGroup.html#iot-AddThingToThingGroup-request-overrideDynamicGroups flag to make static groups take priority over dynamic groups.
  • Note
    This operation is eventually consistent. In other words, changes to the thing group might not be reflected immediately.

    If you try to delete a thing group that has child thing groups, you receive an error:

    You can attach a maximum number of two policies to a group.
  • Note
    We don't recommend using personally identifiable information in your policy names.

Dynamic thing groups

  • Note
    We don't recommend using personally identifiable information in your dynamic thing group names.
  • Note
    After you create a dynamic thing group, you can use the group, regardless of its status. Only dynamic thing groups with an ACTIVE status include all of the things that match the search query for that dynamic thing group. Dynamic thing groups with BUILDING and REBUILDING statuses might not include all of the things that match the search query.
  • Note
    If you have permissions to query the fleet index, you can access the data of things across the entire fleet.
