I'm not expert in programming, but I like to do it for fun, it's like a puzzle!
So I've started to write my own app for efficiency purpose, since some of my somewhat complicated RM were a significant load for my hub. By writing dedicated custom apps, it reduces significantly the time spend to do the job in comparison to an equivalent RM as mentioned here: Writing your own "rule" apps worth it?
One of my RM is logging information into a txt file for further analysis with another computer. However, for what I understand, it is not currently possible to write local file into the hub with custom app since java.io.File cannot be imported. I'm sure this is for security reason.
Another nice guy has developed a way around: [BETA] Hubitat File Driver (HFD) but it still not solves my problem, since this method is based on a RM to write the file. The RM that I want to replace is currently a significant load for my hub.
So, my request/question, could it be possible to allow custom app to write file only into the File Manager? Although not mandatory, it will be a nice to have!
Just to clarify, in no way I want to diminish the RM app, it is super impressive all of the thing that we can do with it.
