That all seems fine.
When did you last run an update ?
Can we see your emonpiupdate.log?
Did you do anything around the time the data stopped, eg using the sync module, updating, change any settings etc?
[edit]
I also noticed that your server info showed the buffer as “loading…” is that still the case? Looking at one of your previous posts (Input list doesn't load - #10 by ivancaregnato) that has previously showed a status like “60 feed points pending write” but I do not know if this is significant.
Plus, have you recently updated the OS packages using apt-get? It’s just I notice you are now running Mosquitto v1.4.14 where as the images installed version was originally 1.4.10 (also seen in your previous post), but again I have no idea if this is significant yet.
