The tariff-savings specialist.
Ohme Home Pro & ePod
Ohme is built around one idea: charge when electricity is cheapest and greenest. It plugs deeply into smart and dynamic tariffs and shifts your charging into the cheap half-hourly slots without you lifting a finger. The range comes in two shapes: the Home Pro, a tethered unit with a built-in cable and a 3-inch colour screen, and the ePod, a compact untethered box for tighter spaces. Both share the same tariff brain, and both carry their own built-in mobile SIM (data covered by Ohme for the first three years), so they keep working without leaning on your home Wi-Fi. The choice between them is really about cable style, screen and size. If your main goal is to cut the running cost of your car, this is the range that leans hardest into that.

Who the Ohme suits
Drivers who are on, or moving to, a smart or dynamic electricity tariff and want the charger to do the cost-cutting for them automatically.
In short: Pick Ohme if cutting your overnight charging bill on a smart tariff is the main event: the Home Pro for a built-in cable, the ePod for a compact untethered unit.
Ohme is the tariff-savings specialist, and on a supported smart EV tariff it shifts charging into cheaper slots automatically while staying online through its built-in SIM. Buy the tethered Home Pro if you want a built-in cable and an on-unit colour screen, or the compact untethered ePod if space is tight and you are happy to plug in your own lead. Eligible installations also offer Solar Boost and Solar Only, so having panels is a reason to check the setup rather than rule Ohme out. Confirm the installation, app and CT requirements, how the selected mode uses grid power, and support for your actual NI tariff before choosing.
What stands out
The strengths that tend to matter when people choose the Ohme.
Deepest tariff integration
Connects directly to smart tariffs (including dynamic, half-hourly pricing) and charges in the cheapest windows automatically, on both the Home Pro and the ePod.
Set a target, walk away
Tell the app the charge level and time you need the car ready, and it works out the cheapest way to get there overnight.
Two units, one brain
Choose the tethered Home Pro for grab-and-go convenience, or the smaller untethered ePod where wall space is tight; both run the same smart-charging software.

The two Ohme units
Same charging smarts, different bodies. Here is how they differ and who each one suits.
Ohme Home Pro
The Home Pro is the tethered unit in the range, and the one to pick if you want grab-and-go with nothing to plug in each night. It is the larger of the two at 170mm tall by 200mm wide (about 4kg), and its headline feature is a 3-inch colour screen on the front, so you can see and set charging from the unit itself as well as from the app. The built-in Type 2 cable comes in a 5m or 8m length, and the enclosure is rated IP55 for an outdoor wall. It suits a household that wants the convenience of a fixed cable and likes having a screen and buttons on the wall rather than reaching for a phone every time. The tariff smarts are identical to the ePod, so you are choosing on cable style, screen and size, not on charging ability.
Ohme ePod
The ePod is the compact, untethered unit, and it is one of the most-searched home chargers in the UK for good reason: it is tiny, roughly the size of an A5 notebook at 230mm by 140mm and just 1.5kg, so it sits discreetly where a bulkier charger would dominate the wall. It is a Type 2 socket rather than a fixed cable, so you bring your own lead (most EVs come with one), which keeps the wall tidy and lets you swap lead lengths if your parking changes. There is no screen, just a five-colour status LED strip, so you control it from the Ohme app, and the enclosure is rated IP54. It suits tight spaces, tidier installs and anyone happy to plug a cable in each time in exchange for the smallest possible unit. It runs the identical smart-tariff software as the Home Pro.
Smart features & tariffs
This is Ohme's home turf. It supports smart tariffs, including those where the price changes every half hour, and reschedules your charging live to hit the cheapest slots. Paired with a good EV tariff it can be the difference between charging at peak rate and charging for a fraction of it. Support for a GB tariff does not establish NI availability: confirm your actual supplier, tariff and integration before relying on it.
EV tariffs in NI explainedSolar charging
Solar-aware charging is available on most Home Pro and ePod chargers with a complete setup installed from January 2023 onwards, app version 2.10.2 or later and a CT clamp providing a reading. Solar Only waits for at least 1.44kW of surplus and has no ready-by target; Ohme notes about 15 seconds of grid use when solar is interrupted before charging pauses. Solar Boost can use grid power to meet a scheduled target and, where available and selected, to top up low solar. Ask the installer to confirm eligibility and settings for your exact setup.
Compare with the ZappiTethered or untethered?
The two units split the choice for you. The Home Pro comes with a built-in (tethered) cable, so there is nothing to carry and nothing to plug in each night. The smaller ePod is untethered: you bring your own lead, which keeps the unit compact and the wall tidy, and lets you swap cable lengths if your parking changes. Same charging smarts either way, so pick on cable style and size, not on features.
Electrically it makes no difference: it's a 7kW charge either way. Tethered is grab-and-go convenient; untethered keeps the wall tidy and your cable flexible. If you're unsure, note it on your quote and the installer will advise for your driveway.
Things to weigh up
No charger is right for everyone. The points below aren't dealbreakers, just the trade-offs to factor in.
- The big wins come when it is paired with a smart or dynamic EV tariff; on a flat-rate tariff you lose most of its advantage.
- Solar support depends on the model and complete installation, including a working CT reading and app version 2.10.2 or later; do not assume an older Ohme qualifies.
- Decide between the tethered Home Pro and the untethered ePod before you book: they charge identically, but the ePod means keeping a cable to hand while the Home Pro is bulkier on the wall.
Whichever charger you choose, the install must be notified to NIE Networks, which is a legal requirement in NI. Our registered installers handle that paperwork as standard. See the full cost breakdown, check your grant, or see how comparing 3 quotes works.
Ohme Home Pro & ePod review
Our neutral assessment, drawn from the manufacturer's specifications and widely-reported owner experience. We do not sell or fit hardware, so this is a buyer's-eye view, not a sales pitch.
Two units, one tariff brain
The thing to understand about Ohme is that the Home Pro and the ePod charge identically. Both are 7.4kW, both integrate with smart and dynamic tariffs, and both carry their own mobile SIM so they stay connected without your home Wi-Fi, which is a genuine advantage for a detached garage where signal is thin. The differences are physical: the Home Pro is the larger tethered unit with a 3-inch colour screen, the ePod is the compact untethered box with just an LED strip. Choose on cable style and size, not on features.
Tariff behaviour: the reason to buy
This is where Ohme earns its reputation. It integrates directly with smart and dynamic tariffs, including the half-hourly kind where the unit price changes through the night, and it reschedules charging live to land in the cheapest slots. You tell the app the charge level and the time you need the car ready, and it works out the cheapest route there. Paired with a good EV tariff, owners commonly report this is the feature that pays the charger back. On a flat-rate tariff, though, you lose most of that advantage, so the value is tied to the tariff you are on.
Solar setup and trade-offs
Eligible Home Pro and ePod setups support Solar Boost and Solar Only, subject to the installation, app and CT requirements above. Solar Only waits for surplus without a ready-by target; Solar Boost can import grid power to meet a target or supplement low solar, depending on settings. Check the daytime rate before enabling grid top-up. The design is functional rather than a statement, and the ePod in particular is plain (which is the point).
Who should skip it
If solar surplus charging is essential, confirm that the quoted Ohme setup qualifies before buying; an older installation or missing CT reading needs an installer check. If you have no solar and are staying on a flat-rate tariff, or want a design-led charger, weigh the alternatives. For tariff savings, confirm support for the tariff you can actually get in NI, then pick the Home Pro or ePod on cable and size.
Ohme: common questions
Is the Ohme tethered or untethered?
Tethered or untethered. The two units split the choice for you. The Home Pro comes with a built-in (tethered) cable, so there is nothing to carry and nothing to plug in each night. The smaller ePod is untethered: you bring your own lead, which keeps the unit compact and the wall tidy, and lets you swap cable lengths if your parking changes. Same charging smarts either way, so pick on cable style and size, not on features.
Is the Ohme good for solar panels?
Solar-aware charging is available on most Home Pro and ePod chargers with a complete setup installed from January 2023 onwards, app version 2.10.2 or later and a CT clamp providing a reading. Solar Only waits for at least 1.44kW of surplus and has no ready-by target; Ohme notes about 15 seconds of grid use when solar is interrupted before charging pauses. Solar Boost can use grid power to meet a scheduled target and, where available and selected, to top up low solar. Ask the installer to confirm eligibility and settings for your exact setup.
Does the Ohme work with EV electricity tariffs?
This is Ohme's home turf. It supports smart tariffs, including those where the price changes every half hour, and reschedules your charging live to hit the cheapest slots. Paired with a good EV tariff it can be the difference between charging at peak rate and charging for a fraction of it. Support for a GB tariff does not establish NI availability: confirm your actual supplier, tariff and integration before relying on it.
