I’ve been using an EmonPi/EmonCMS for a few years with no issues. I have recently started to get an error in the logger relating to a feed not existing
Did you delete some default feeds, or do you have any other idea what would have caused this? It sounds like something is still trying to read from an old feed for some reason.
Did you try a reboot.
I am not an expert, I am just trying to help. We need more information.
If you look at the Feed List page, it lists the feed IDs of each feed down the left-hand side. So it should be easy to see what these feeds are if they exist, or otherwise confirm that they don’t exist.
The error message is more likely to be caused by something looking for a feed that no longer exists, eg feeds were deleted that are still referenced in the input processlists or in dash/graphs etc. Or perhaps a external script eg node-red? is trying to query those deleted feeds.
