Ohme is a London-based EV charging company that takes a deliberately narrow focus: it makes smart EV chargers and builds the deepest tariff API integrations in the UK market, without venturing into solar panels, home batteries, or hot water diverters. If your priority is charging your car at the cheapest possible rate — particularly on Octopus Intelligent Go — Ohme is designed specifically for that goal.
For a broader picture of how charger-only ecosystems fit into the full home energy landscape, see our home energy ecosystem guide.
What is the Ohme ecosystem?
Ohme’s ecosystem is built on two components: the charger hardware (two models — Home Pro and ePod) and the Ohme app, which acts as both scheduler and tariff integration layer. The company was founded in London and has established itself as the charger brand most associated with Octopus Energy’s Intelligent Go tariff.
Rather than building its own energy management software for solar or batteries, Ohme’s strategy is to build the best possible connection between your charger, your car’s battery, and your energy tariff. The Ohme app pulls real-time half-hourly rate data from Octopus’s API and automatically schedules charging to minimise cost based on how much charge your car actually needs.
The Ohme product range:
- Ohme Home Pro — 7.4 kW, LCD screen, PIN lock, tethered cable
- Ohme ePod — 7.4 kW, compact, no screen, tethered or universal socket
Both are OZEV-approved for the EV chargepoint grant, and both include O-PEN (Open Protective Earth Neutral) fault protection.
Ohme Home Pro
The Ohme Home Pro is the flagship model, aimed at homeowners who want visibility of their charging cost and session data without opening their phone. The onboard LCD screen shows current draw, energy cost, session cost so far, and charging schedule at a glance.
Home Pro specifications:
- Charging output: 7.4 kW (single-phase 32A)
- Connector: Type 2 tethered, 5 m or 8 m cable options
- Display: LCD screen showing rate, cost, and schedule
- Security: physical PIN lock
- O-PEN fault protection: built in
- OZEV chargepoint grant: approved
- IP rating: suitable for UK outdoor installation
The PIN lock is a useful feature for households that share a driveway or want to restrict access to the charger. The Home Pro is the more premium-feeling unit: it is larger than the ePod and feels substantive at the wall, with the screen giving it a presence that the compact ePod lacks.
Ohme ePod
The ePod is Ohme’s second model — smaller, lighter, and without an onboard screen. All control and scheduling happens through the Ohme app. There is no physical PIN lock; access security is managed via the app only.
ePod specifications:
- Charging output: 7.4 kW (single-phase 32A)
- Connector: Type 2 tethered, or universal socket (untethered)
- Display: none — app only
- O-PEN fault protection: built in
- OZEV chargepoint grant: approved
The ePod is the more popular choice for renters and flat residents applying for the OZEV grant, partly because its lower price point makes the economics of the grant more favourable, and partly because its compact form factor suits a wider range of install locations.
Both models have the same core tariff integration capability. The choice between them comes down to whether you want an onboard screen and physical controls.
The Ohme app
The Ohme app is the centrepiece of the ecosystem. It handles:
- Automatic smart scheduling: The app pulls your tariff’s rate schedule and calculates the cheapest time windows to deliver the charge your car needs by your target departure time.
- Cost tracking: Session cost in pounds and pence, with a tariff-aware per-kWh breakdown.
- Charge Anywhere: A feature that allows you to log public charging sessions alongside home sessions, giving you a unified view of your EV energy spending.
- Integration management: The app manages the connection to Octopus, OVO, and other supported tariff providers.
The scheduling logic is sophisticated. Rather than simply starting at 23:30 and stopping at 05:30 (the standard Octopus Intelligent Go window), Ohme can extend the cheap window dynamically if Octopus grants additional cheap periods based on grid conditions. This means that on some nights your car receives extra cheap electricity beyond the standard window — a benefit unavailable to households using a manual schedule or a less deeply integrated charger.
Smart tariff integration
Ohme’s native Octopus Intelligent Go integration is the deepest in the UK EV charger market. The way it works:
- You connect your Octopus account to the Ohme app
- You tell the app your target departure time and the charge level you want
- The app communicates with Octopus’s API, which knows the available 7p/kWh windows for your meter
- Ohme schedules charging within those windows and pauses outside them
- If Octopus grants additional cheap periods (based on grid demand management), Ohme continues charging at 7p even after 05:30
This last point is important. Octopus Intelligent Go is a demand-management tariff: Octopus can extend the cheap window when the grid needs EV charging load to absorb overnight wind generation. Chargers with native API integration — Ohme being the primary example — benefit from these extensions automatically. Chargers on manual timers stop at 05:30 regardless.
Other compatible tariffs:
| Tariff | Integration type |
|---|---|
| Octopus Intelligent Go | Native API — deepest integration |
| OVO Charge Anytime | Native integration |
| EDF GoElectric | Schedule-based |
| E.ON Next Drive | Schedule-based |

Why Ohme has no solar or battery hardware
Ohme’s positioning is a strategic choice, not a gap. The company’s thesis is that for a large segment of UK EV owners — particularly those in rented accommodation, flats, or newer homes without south-facing roofs — the relevant question is not “how do I build a full home energy ecosystem?” but “how do I charge my car at 7p per kWh tonight?”
Ohme answers that question more cleanly than any competitor. You buy the charger, you connect your Octopus account, and your car charges cheaply. No gateway, no Hub, no inverter, no CT clamp survey required.
For households with solar panels, Ohme provides limited solar mode capability via a CT clamp configuration — it can reduce charging during solar surplus to avoid export — but it does not offer active solar diversion equivalent to Zappi’s Eco+ mode. If solar self-consumption is a priority, myenergi or Hypervolt are the stronger choices.
How Ohme compares
| Ohme | myenergi | GivEnergy | Hypervolt | |
|---|---|---|---|---|
| Charger models | Home Pro, ePod | Zappi | GivEnergy EV | Home 3 Pro |
| Battery | No | Libbi 5–20 kWh | AIO 13.5 kWh | No |
| Solar modes | Limited (CT clamp) | Eco+ / Eco / Fast | Solar Boost | Three modes |
| Octopus IG API | Native (deepest) | Compatible | Scheduler | Native |
| Octopus Flux | Compatible | Native | Scheduler | Compatible |
| Screen | Home Pro: yes, ePod: no | No | No | No |
The Ohme vs Hypervolt comparison is the closest, as both focus on the charger and tariff layer. The key difference: Ohme leads on Octopus IG depth; Hypervolt leads on solar mode sophistication. See the full ecosystem comparison for detailed guidance.

Frequently Asked Questions
What is the Ohme ecosystem? The Ohme ecosystem consists of an EV charger (Home Pro or ePod), the Ohme app, and deep integrations with smart energy tariffs, particularly Octopus Intelligent Go and OVO Charge Anytime. It is not a full home energy stack — Ohme makes no solar diverter, battery, or inverter hardware. Its focus is making EV charging as cheap as possible through intelligent tariff scheduling.
What is the difference between Ohme Home Pro and ePod? Both deliver 7.4 kW and include O-PEN protection and OZEV approval. The Home Pro has an onboard LCD screen showing charge rate, session cost, and current schedule, plus a physical PIN lock for access security. The ePod is smaller, has no screen (all control via the app), and is available in tethered or universal socket form. The core tariff integration capability is identical on both models.
Does Ohme work with solar panels? Ohme offers limited solar interaction via a CT clamp configuration — it can reduce its charge rate to avoid exporting surplus solar to the grid. However, it does not offer active solar diversion equivalent to myenergi’s Eco+ mode, which modulates charging between 1.4 and 7.4 kW in real time to match surplus exactly. If solar self-consumption is a primary priority, Hypervolt or myenergi Zappi are better matched.
Which tariffs work with Ohme? Ohme supports Octopus Intelligent Go (native API with automatic schedule extension), OVO Charge Anytime (native integration), EDF GoElectric, and E.ON Next Drive via schedule-based integration. Native API integrations automatically extend or adjust your cheap charging window based on real-time tariff data; schedule-based tariffs require you to set the charge window manually in the app.
Is Ohme approved for the OZEV chargepoint grant? Yes, both the Ohme Home Pro and ePod are on the OZEV approved product list. The grant of up to £350 is available to residents of flats and rented accommodation (tenants, housing association and social housing residents, and landlords who install for tenants). Check gov.uk for the current approved list and eligibility criteria before purchasing.
