Methods and systems of enforcing a demand reset in a meter (114a) that communicates via a wireless network. When billing data is received by a server (206), it is accompanied by a demand reset counter. The counter is compared to a counter stored on the server (206). If they received counter is less than the server counter, it is determined that the meter (114a) missed a demand reset. The server (202) then instructs the meter (114a) to perform a demand reset to ensure that accurate demand data is recived by the server (206).
