It has 305 installs sharing analytics, needs the vendor's cloud and was last updated August 19, 2026. Ontario Energy Board is a Home Assistant integration that shows current energy rates for Ontario electricity and natural gas companies. It adds a device per configured company, with sensors for the current rate, the active peak period and the individual charges that make up a bill. Rates follow the Time-of-Use or Ultra-Low Overnight schedule through the day, including Ontario holidays, and the rate plan can be changed later in the options. A current all-in rate sensor can serve as a price source for cost tracking in the Energy dashboard, and next peak sensors let automations wait for cheaper power. Rates come from published open data of the Ontario Energy Board, so the integration needs a cloud connection, and it is set up in the UI. It is community-maintained and not affiliated with the Ontario Energy Board. Automatic summary of the README and code of jrfernandes/ontario\_energy\_board.
