Now the module works fine but since the last update on yesterday there is a Message on my MM that there is an update for your module available.
I did
git pull
npm install --omit=dev
in the module-folder from your module but the update-message is still shown in the MM
@bkeyport
I found an old Data backup from my Raspi SD-Card and restored it.
Now erverything works fine again (as long as I make no Raspi-update)…
Thanks for your help!!!
