Hi all,
I have now published this to the Plugin Store, and it seems very stable but it has only been tested by me. This version supports updates via the API which you can get with a "free" account from Glowmarkt, or for real time energy usage direct from your smart meter the MQTT version that requires you to purchase the Glowmarkt IHD/CAD that connects to your UK smart meter. You get real time electricity usage, and near real time cost and usage for electricity and gas. It utilises FlyingDivers excellent MQTT plugin that does the heavy lifting for MQTT.
https://github.com/neilkplugins/Glow-IHD-CAD-indigo-plugin/wiki for the documentation.
Any questions, problems or requests let me know. It also works incredibly well with the Grafana plugin, and I am also embedding the Grafana dials in my control page for energy usage.
Here is the ugly control page
and my Grafana Dashboard (not all of it)
Just adding some new functionality to the Octopus Energy plugin as well so that it calculates the best time to run a load for 30m, 1hr, 2hr, 3hr or 4hr to get the lowest rates and a new version will be published that also gets at your usage data.
