Abstract
Various arrangements for handling delayed status update are presented. A network-enabled sensor unit may be used to measure an environmental condition. The sensor unit may determine, based on measuring the environmental condition, an environmental condition status has changed state. A network connection may be established that permits communication with a remote notification service system. This notification service system may maintain a remote status intended to be synchronized with the environmental condition status of the sensor unit. The sensor unit may determine that the environmental condition status has changed prior to communicating the environmental condition status to the notification service system. A historical status array may be transmitted to the notification service system in response to determining the environmental condition status has reverted to the first state prior to communicating the environmental condition status. The historical status array can indicate previous states of the environmental condition status of the sensor unit.
