Yeh I have this, I started a thread a while ago but couldn’t find the cause EmonHUB Crashing - #24 by Dave
The way I overcame this is by putting a watchdog on NodeRED that monitors the update of my emonpi and if it exceeds 60 secs it restarts emonhub service and pushes me a message.
Every now and again thou it crashes and the watchdog doesn’t pick it up.
Just import the below code into NodeRED…

Dave
