ComEd Hourly Pricing

The ComEd Hourly Pricing program is an optional program available to ComEd electric subscribers which charges customers a variable rate for electricity supply based on current demand rather than a traditional fixed rate. Live prices are published here and also via an API which we can integrate as a sensor in Home Assistant.

There are two price feeds available: the 5-minute price and current hour average price.

To use this sensor in your installation, add the following to your configuration.yamlThe configuration.yaml file is the main configuration file for Home Assistant.
