I’ve had a couple of occasions where, usually after doing a system update, my emonpi has stopped processing inputs. I’ve only noticed after a few hours when I happen to login and spot it. At that point, I can see on either the input or feeds page that the age is highlighted in red and out-of-date.
I’m thinking that there must be a simple way to check for aged feeds, which I could set up to monitor externally. Is there a RESTful call I can use to see this, or perhaps something with MQTT? Or is it readily scriptable to push something out from the Pi? Sorry if it’s an obvious facility I’m missing, but I couldn’t find it either by searching or trawling through the docs. It seems unlikely that I’m the first person to want to do this
