Thank you for checking! Really appreciate the help.
It might be a while before I can update to 2.3.8. I currently run 2.3.5, which has been really, really stable for me. I have a razberry2 and a RPI3+ (as I was hoping to have a secondary controller, but without lifeline updates, the secondary controller isn't that useful), so what I might do is;
- exclude the FLS100+ from my 2.3.5 network.
- format my RPI3+ with the razberry2. Then install 2.3.5 and include the FLS100+
- see if the same behaviour happens.
- upgrade to 2.3.8-rc6 and see if the problem has been fixed.
The shell script workaround is solving my current problem, but definitely want the proper fix in place!
