      Where can I find my P1 port and what should I do if it's already occupied?

      Your P1 port is the connection on your smart meter that can be used to read your energy consumption. Read below how to recognize it and what you can do if it's already in use.

      Where do I find the P1 port?
      • Usually on the side or bottom of your smart meter. There may be a protective cap in front of it.  
      • Recognizable by an RJ12 connector (similar to an internet cable, but narrower)
      What if the P1 port is already occupied?

      No problem! Our WattsOn has a built-in P1 extender:
      1. Connect your current device to the WattsOn's “P1 OUT” port
      2. Connect the WattsOn itself to the P1 port of your smart meter, please follow those instructions
      3. Done - now you are reading both your existing device and the WattsOn without any problems
      Note: Do not forget to remove the protective cover of the “P1 OUT” port with a screwdriver.
