I just installed the latest emoncms SD image on my RasPi 3B and started setting things up.
When I went to inputs, a bunch were there - all five of my nodes were represented with fresh data. I assume that the inputs were created automatically when the data came in. I set up a few of them with feeds.
But then, I realized that in my previous installation, my inputs had names I had assigned, so I wanted to do that here. I discovered that I could change the name by checking the box by the input, hitting the edit icon, changing the name, and saving it.
I did this with two inputs.
Then I noticed that my inputs had no data, but new inputs had appeared, each with the old name, and had data. The feeds for my renamed inputs also now show stale data, and the new inputs have no feeds.
Hence, it appears that renaming an input disconnects it from the data coming in, and when that data appears, since it is unrecognized, new inputs are created.
Is this a known bug? Is there a way around it other than hacking the SQL database or something?
