During the week I was not convinced that the Safale-S04 yeast had come to life, after 3 days the RRD-tools graphs stopped generating....
A bit of late Friday evening hacking to get Kibana for the temperature graphs. I was hoping to use a spare raspberry pi for this - but got a bit frustrated with ARM vs x86 architecture. So instead gone with a crude python script to subscribe the multicast temperature data and republish it direct to logstash.
From there it's pretty basic ELK stack, albeit running on something beefier than really required.
I'll either just spin up an old laptop to provide Kibana for the crucial weeks of fermentation *or* compile the ELK stack on ARM.
