Home Assistant Power NI

A HACS custom integration that scrapes live electricity tariff prices from powerni.co.uk and exposes them as Home Assistant sensor entities.

All prices are the Best Deal incl. VAT for each tariff section and refresh every hour.

Why scraping?

Power NI does not offer a public API or data feed for tariff prices. There is no official Home Assistant integration, no unofficial community integration, and no machine-readable endpoint — pricing is only published on their website. Web scraping is therefore the only viable mechanism to retrieve this data programmatically.

A daily automated test monitors the live page and raises a GitHub issue automatically if the website structure changes and prices can no longer be extracted.
