During development using an iOS SDK, a control command was sent, but the device did not report its status. How can I solve the problem?

1. Check whether the data type of the data point is correct. For example, if the data type of the data point is a numerical value, the control command sent should be @{@"2": @(25)} instead of @{@"2": @"25"}. 2. Check whether the data point supports only data reporting, but not data delivery.
