I have been using an OWL device which clips onto the live tail (meter to CU) and sends wireless reading to a remote display. Yesterday the meter installers gave me a display which reports lots of information about my usage and ongoing bill. (This communicates remotely with the meter). This morning the Owl reads 305W and the Smart sender reads 206W. Which do you think is correct? I'm only using a few lights, standbys and the TV at the moment so they are both credible. Could they possibly conflict?
