I have created a custom driver and Dashboard Tile to poll the ComEd Website and get the Hourly and 5-minute rates. I use these values to create rules to turn off appliances and adjust my thermostat settings—this way, when the rate is $1.63 per kilowatt, you're not running your air conditioning.
I’d be interested. I’m currently doing all kinds of automations based on the rates but can only get them via home assistant. A direct feed option is always preferred.
