Systems and methods are disclosed for detecting node outages in a mesh network. A tracking node in the mesh network detects a set of signals originating from a tracked node in the mesh network. The set of signals includes beacons or communication messages transmitted by the tracked node. The tracking node determines that a threshold number of the beacon intervals have passed since receiving the most recent signal from the tracked node. The tracking node performs outage validation based on data received from another node in the mesh network and updates the status of the tracked node. Based on the updated status, the tracking node outputs a ping to the tracked node requesting a response to the ping. When the response to the ping is not received from the tracked node, the tracking node transmits an outage alarm message to a next topologically higher layer of the mesh network.

An electric meter in a utility box is capable of detecting arcing conditions between meter blades and a meter socket in the utility box at a premises. The electric meter includes a current-transformer structure forming an enclosed space. An arc detection antenna can be placed in the enclosed space along with the current transformer.

A method for detecting electric meter installation issues includes: determining an initial orientation of an electric meter based on initial acceleration measurements from an accelerometer positioned in the electric meter. Subsequent acceleration measurements from the accelerometer may be continuously monitoring, and a subsequent orientation of the electric meter may be determined based on the subsequent acceleration measurements. A difference between the initial orientation and the subsequent orientation based on the initial acceleration measurements and the subsequent acceleration measurements may be determined and compared to a threshold value. Based on the difference exceeding the threshold value, a notification of a change in orientation of the electric meter may be generated to a head-end system.
