The charger Octopus pushes hardest for Intelligent Octopus Go households, and for good reason — its own smart-scheduling already targets your cheap-rate window, so pairing it with Home Assistant is mostly about layering extra automations (solar-aware boosts, notifications) on top rather than replacing what it already does. Ohme now has an official core Home Assistant integration (no HACS install needed), which puts it on firmer footing than community-maintained rivals like the Hypervolt entry also on this site — though it's still entirely cloud-dependent, same as every EV charger catalogued here.
In Home Assistant
The dan-r/HomeAssistant-Ohme integration (installable via HACS) polls Ohme's cloud API — session data every 30 seconds, device settings every 30 minutes — exposing charge state, session energy sensors, and basic start/stop/target controls. If your Ohme account was created via Apple/Facebook/Google sign-in, you'll need to set a password via Ohme's password-reset flow first, since the integration authenticates with email + password rather than social login. No local control path exists; it depends entirely on Ohme's cloud. NOTE: this description was written for the community HACS integration — Ohme now also ships an official core Home Assistant integration (see verification_notes), and the polling/auth specifics above should be re-checked against that before publishing.
