I have 2 charts running in my office all day. One is energy load and one is energy pricing. I also have the current energy price displayed on a screen in our kitchen. This has worked to change our habits pretty well. For instance we now consider it “expensive” to run the dishwasher during the day. We’ll do it if necessary but there is now a mental barrier to doing so.

This is amusingly interesting to me. I’d love to know more about your setup and the results make sense (I’ve considered installing a second dishwasher to be able to handle an entire days worth of dishes overnight) but it also seems somehow slightly dystopian. I agree with the note later in the thread that the solution is powerwall like things for demand smoothing / moving.

  The screen in my kitchen is a dakboard (https://dakboard.com/site https://dakboard.com/site) we largely use it as a digital picture frame and calendar but it supports querying/parsing json out of the box. So to get the price on it I have it hit my providers json api https://hourlypricing.comed.com/hp-api/ https://hourlypricing.comed.com/hp-api/. For the charts in my office I have a Prometheus/Grafana setup at home for a variety of things and built a bridge to the comed data for Prometheus (https://github.com/kklipsch/comed_exporter https://github.com/kklipsch/comed_exporter). For usage data I have a neat gadget called a Rainforest Automation Eagle (https://www.rainforestautomation.com/compare-emu-and-eagle/ https://www.rainforestautomation.com/compare-emu-and-eagle/) that reads my smart meters radio signal. It exposes an xml api and I wrote a bridge to Prometheus (https://github.com/kklipsch/reagle https://github.com/kklipsch/reagle). Once it’s all in Prometheus the Grafana dashboards are pretty straight forward affairs.
