Just got a 2 pack of these plugs today. Plugged it into an outlet with nothing connected just to configure it. It took a few tries, but I finally got it configured and showing results in Home Assistant. I moved it and connected a computer to it. No good. The LED is just flashing blue (don't know if that's what it's supposed to do or not) and can't see it on Home Assistant. It does show up on the router as being connected. Any ideas?
