Thanks for making this available. I installed influxdb and grafana on my Ubuntu system and had data logging and charted in less than an hour. The influxdb logging app on my HE installed without a problem.
Here's a sample set of graphs: one is to help me verify the correct functioning of some rules that control how a hot water recirculation pump is cycled; and the other shows various temperature sensors around the house.
Thanks again for a great addition to my home automation system.
