I have been working on the tweet-a-watt project and everything has been going great. However I have noticed some problems with a couple of the tweet a watts. After plugging them into the wall and running the python code in debug mode in order to calibrate them. Some of them don't show consistent current numbers. There is nothing plugged into these kill a watts.
Also when I was checking the tweet a watts I noticed that the VA reading was not at zero when I was testing them, also with nothing plugged into them. I didn't check the kill a watts before installing the transmitter chip. So I am not sure if its a problem with the kill a watt or if I maybe short circuited something?
This is the data I get in debug mode.
