Red LED-No ssid available for Iotawatt

The Iotawatt unit was working unmounted but connected to 5v supply soon after arriving.
However, I unplugged it to install it.
Now I just see a red light.
I went into my router to look for it.
It is not showing in the device list.

I am a new user.
Any help would be greatly appreciated.

The AC reference must be plugged in. It also sounds like it is not connected to WiFi. Try powercycle and watch for RGG led for the first 3 minutes, then it goes to Red if not connected. While it is RGG you should be able to configure WiFi as in the docs for anew unit.
