Answer

No, there will be no interference. When you synchronize the Display to the Sensor, they each get a unique address so they only receive signals from the sensor they are synchronized to.

However, please be aware the display must be located within 60 feet of the meter and going through only 1 exterior wall. In large apartment complexes where the meters are more than 60 feet away and/or have several exterior walls between the meter and the apartment, the power monitor will not be able to receive a signal.
