For completeness, and as these issues remain and may or may not not be resolved until the next update, I’ve described how I get around these problems.
Unfortunately the post processing module also has issues which need to be resolved. Here’s an example:
No “OK” button. Strangely, the problems encountered with the Post Processing module differ at random. (I know the [Return] key has to be pressed for the [OK] button to appear.)
Also, unable to use Virtual Feeds to create calculated feeds as only physical inputs may be used as inputs to the Virtual Feed and many calculated data need virtual feeds as input.
To conclude Post Processing and Virtual Feeds come up short and I don’t have the knowledge to resolve this myself.
In my opinion not having the ability to create ‘calculated feeds’ is a ‘dent in the armour’ of EmonCMS and greatly reduces its usefulness in converting Data to Information. I must also say that EmonCMS is great and the work that has been put into it is commendable, I hope I’m not perceived as being too critical.
Currently the only way I know how to do what I need to do is to use Node RED for the UI, send any data needed back to EmonCMS via MQTT for data storage only, and do all calculations in Node RED.
Best wishes,
