Water Heater / EV Charger / Mower Charging -- Nord Pool Price-Based Blueprints

Hi all,

I built a small set of Home Assistant Blueprints on top of the native Nord Pool integration, for anyone in the Nordic/Baltic electricity markets (FI, SE, NO, DK, EE, LV, LT) who wants price-based automation without writing their own templates from scratch.

Four Blueprints so far, all free, all open source:

  • Price Alert — notify when price crosses a threshold you set
  • Water Heater / Boiler Timer — run during the cheapest hours (or under a price ceiling), with a safety fallback so you’re never left with cold water on an expensive day
  • EV Charger Scheduling — same idea, plus a deadline mode (“charge X hours, ready by 7am”)
  • Robot Mower Charging — same as above, tuned for mower charging docks

They only need your existing Nord Pool sensor and a switch entity (smart plug or your device’s own charging switch) — no separate account or service required.

Repo + one-click imports: GitHub - saveelectro-app/ha-blueprints: Home Assistant Blueprints for SaveElectro price-based automations (price alerts, water heater scheduling, and more) · GitHub

If you’ve got an idea for another use case, there’s a pinned issue on the repo for suggestions — happy to build more if there’s demand.

(Small disclosure: I also run SaveElectro, a WordPress plugin (listed as “Save Electro” in the plugin directory) for displaying/alerting on these same prices outside of HA — not required for any of this, just flagging the connection since I’m not a neutral third party here.)
