Thank you !
I grabbed your code, and of course, it compiled first time. Then I modified your buttons and sensor definitions to fit my case and recompiled it. It died the first time because I had trash left over from other tests, So I cleared it and reloaded and it worked right away … except for what you just described above about the converter.
Then, I went looking for the data directory. I can’t find that thing anywhere. I have HAOS, and I did find the config file, but it didn’t have an entry for the data directory. Sigh … I’ve encountered this problem before; none of the directories are where they are supposed to be and each description of where they are seems to be different.
I’ll report back here after I play a bit more… and Thanks Again for the help so far.
