I recently did an apt-get upgrade (only for the Linux OS and Homegear - not OH2) and since then my (4 month old) OH2 Nighly 4.1 build is playing up.
It keeps forgetting the configured things (especially the Homegear things) and after each restart I need to add them again.
Anyone had similar issues or an idea what might be the reason?
On a Pi or other board based computer? That sounds a lot like the SD card is corrupting.
If not look through the logs for Uninstalled messages. If you see them then come back and we will continue to diagnose.
Yes a Raspi. I suspected sth. similar and changed the card. I also took the chance to switch to the stable version. Looks good so far.
