Yeah maybe - I just was curious that it could run so long, and then crash after a restart.
Hopefully I don’t have to put some more effort in it 
This night it ran flawlessly.
This morning I now did:
- Reduce the number of HTTP Caches to one (thanks to @vzorglub with [SOLVED] Use jsonPath in JavaScript transformation? - #9 by vzorglub)
- Updated OpenHAB to 2.4.0
So let’s see - first 20 minutes look god, hopefully next 20 days too.
