Error - The call for sensor L3 experienced a timeout. You are probably not in the same local network as the FLM.‏

Hello,

i have a big problem with a flukso electrical sensor. In the minute display i get every time the error: "Error - The call for sensor L3 experienced a timeout. You are probably not in the same local network as the FLM.‏"

Is the sensor L3 broken?
