Charger review
Ohme Home Pro review: the smartest charger for Octopus Energy users.
The Ohme Home Pro is built around tariff intelligence. It connects to your energy account and schedules charging in the cheapest windows automatically: no manual setup needed. For Octopus Agile users, it is unmatched.
Verdict
The Ohme Home Pro is the right charger for drivers on smart tariffs, particularly Octopus Agile or Go. Its energy account integration is the best of any home charger: it reads your tariff pricing directly and schedules charging without you having to configure anything beyond your desired departure time and target state of charge.
If you are not on a smart or overnight tariff, the Ohme's main advantage over a Pod Point Solo 3 is reduced. And if you have solar panels, the Zappi has deeper solar integration. The Ohme sits squarely in its own lane: the most intelligent charger for the standard grid + overnight tariff use case.

Tariff integration: how it works
Ohme's standout feature is what it calls "intelligent charging." During setup, you link your energy account directly to the Ohme app. The charger then reads your tariff pricing automatically:
- Octopus Go / fixed overnight tariff: Ohme reads your cheap-rate window and schedules charging within it automatically. You set a departure time and target charge level; Ohme works backwards to start charging at the right time.
- Octopus Agile: Agile prices change every 30 minutes based on wholesale electricity rates. Ohme reads the upcoming price schedule and automatically selects the cheapest windows to charge your car overnight, within the constraints of your departure time and target charge. No manual configuration needed as prices change.
- Octopus Flux / time-of-use tariffs: same principle: Ohme reads the pricing structure and optimises within it.
The practical result: on Octopus Agile, Ohme typically charges in the 2–4am window when wholesale prices are lowest. Over a year, Agile users regularly achieve average charging rates below 10p/kWh, and occasionally negative (when grid electricity is free or paid for during surplus renewable generation periods).
What the Ohme does well
- Best-in-class tariff integration: connects directly to your energy account and schedules automatically
- Octopus Agile support: charges in the cheapest half-hour windows without manual configuration
- Clean, compact hardware: slimmer than Zappi and Pod Point
- Transparent cost reporting: shows exactly what each session cost and how it compares to peak rates
- Solar divert available via CT clamp (not as deep as Zappi, but functional)
- OZEV approved: eligible for the EV Chargepoint Grant
Where it falls short
- Tariff integration requires sharing energy account credentials with Ohme: a privacy consideration for some users
- Solar divert is CT clamp only, not direct inverter integration like Zappi
- App occasionally shows connectivity issues reported by some users (usually resolved by router reboot)
- Less established ecosystem than myenergi: no equivalent of the Eddi/Libbi pairing
- If you are not on a smart tariff, most of Ohme's key advantages over Pod Point disappear
Solar divert on Ohme
The Ohme Home Pro supports solar divert via a CT clamp on your main supply. It monitors net import/export and routes surplus solar generation to the car. This works reliably for the core use case: diverting solar surplus when available: but it is not as sophisticated as the Zappi.
Where the Zappi has three distinct modes (fast, eco, eco+) and can combine solar divert with minimum charge rates and time-of-day grid backup, the Ohme's solar handling is more binary. It is good enough for most solar owners who primarily want to avoid exporting at a low rate, but Zappi remains the better choice if solar optimisation is your main priority.
The Ohme app
The Ohme app has consistently been the best-reviewed app of the main charger brands. It shows real-time cost per session (not just kWh), projected savings against peak rate charging, and a clear tariff calendar showing when cheap-rate windows are scheduled. The design is clean and the information is presented in terms that make sense to drivers, not engineers.
Some users have reported intermittent connectivity issues: the charger showing as offline in the app when physically working fine. These are usually resolved by restarting the home router and appear to be related to specific router/Wi-Fi configurations rather than a systematic hardware fault.
Cost and the OZEV grant
The Ohme Home Pro typically costs £850–£1,050 installed. After the OZEV grant (75% up to £500 for eligible renters and leasehold flat owners), the net cost is typically £350–£550.
See the OZEV grant guide for eligibility and how to apply.
Who should buy the Ohme Home Pro?
- Octopus Agile users: the Ohme's automatic Agile optimisation is genuinely valuable and not easily replicated by other chargers.
- Octopus Go / fixed overnight tariff users: Ohme makes tariff setup automatic; Pod Point also works but requires manual window configuration.
- Drivers who want the best app experience: Ohme's cost reporting and UI are ahead of the other main brands.
- Solar panel owners who also want great tariff integration: Ohme handles both, though Zappi handles solar better.
- Standard tariff users with no overnight rate: the Ohme's main advantages do not apply: save money with a Pod Point instead.
Common questions
Do I need to be on Octopus Energy to use an Ohme?
No. Ohme integrates with Octopus, E.ON, British Gas, EDF, Ovo, and several other suppliers. The depth of integration varies by supplier: Octopus has the deepest integration, particularly for Agile. On other suppliers, Ohme can still read your tariff window and schedule accordingly.
Is it safe to link my energy account to Ohme?
Ohme uses read-only API access to your energy account via standard authentication flows: it cannot modify your account or place orders. The connection is used purely to read tariff pricing data. Some users prefer not to share account credentials with third parties, which is a reasonable position; in that case, Ohme still works but requires manual tariff window configuration.
What happens if the Ohme loses internet connection?
The charger continues to charge at the last scheduled time, but cannot update if tariff prices change. For fixed overnight tariffs this is a minor issue. For Octopus Agile (where prices change daily), a temporary loss of connectivity means the charger may not access the cheapest windows until connection is restored. Pod Point's built-in SIM provides a fallback that Ohme lacks.
Can the Ohme work with vehicle-to-grid (V2G) in future?
Ohme has indicated V2G capability is on its roadmap. As of 2026, it is not available on the Home Pro. V2G requires bidirectional hardware that the current unit does not support.
