Indra Smart PRO vs Ohme ePod: British Built vs Smart and Tiny

British Engineering vs the UK's Smallest Smart Charger

Choosing a home EV charger in 2025 often comes down to what you value most: robust hardware with everything in the box, or cutting-edge software in the most compact package possible. The Indra Smart PRO and Ohme ePod represent two genuinely different philosophies, and if you're torn between them, you're probably asking yourself whether it's worth paying more for included extras — or whether a cheaper, smarter unit is the better long-term bet.

The Indra Smart PRO is a proudly British-designed and manufactured charger from Malvern-based Indra, a company with deep roots in vehicle-to-grid (V2G) technology. It comes tethered with a 6-metre cable, includes a surge protection device (SPD) as standard, and bundles a CT clamp for solar diversion — all for £599. The Ohme ePod, meanwhile, strips things back to the absolute essentials: a tiny 1.48 kg untethered unit with industry-leading smart tariff integration and built-in cellular connectivity for just £409. Two very different propositions at two very different price points.

In a nutshell:

• Indra Smart PRO (£599): A tethered, British-made charger that includes SPD and CT clamp as standard, saving you money on installation extras.
• Ohme ePod (£409): The UK's smallest and lightest smart charger, with best-in-class tariff integration and built-in 4G — but you'll need to buy your own cable.

Spec Comparison

Smart Tariff Integration

This is where the Ohme ePod genuinely shines. Its integration with Octopus Intelligent Go is arguably the best on the market — the charger communicates directly with Octopus Energy to access the full off-peak window (typically around 7p/kWh), automatically scheduling your charge sessions to hit the cheapest slots. It also works with Octopus Agile's variable 30-minute pricing, OVO Smart Charge, and British Gas Electric Driver. The "Ready By" scheduling and price cap features mean you can set a maximum price you're willing to pay per kWh and let the charger handle the rest.

The Indra Smart PRO also offers smart tariff integration with major UK providers, and users on forums like speakev.com report that its tariff mode works reliably — you input your tariff details and the charger starts charging when the off-peak rate kicks in. However, the integration isn't as deep or as automated as Ohme's. Where Ohme talks directly to your energy supplier's API, the Indra relies more on user-configured time windows. For someone on a simple off-peak tariff like Octopus Go (7.5p/kWh between 00:30 and 04:30), both chargers will do the job. But if you want to squeeze every penny from Agile's half-hourly pricing, the Ohme ePod is the stronger choice.

At typical off-peak rates of 7p/kWh versus the current price cap of around 24.5p/kWh, smart charging can save a typical UK driver (7,400 miles/year in a Tesla Model 3) roughly £300–£350 annually. Both chargers unlock these savings — but the Ohme makes it more effortless.

Solar Diversion

Both chargers support solar integration, which is increasingly important as more UK homeowners pair rooftop panels with their EVs. The Indra Smart PRO includes its CT clamp in the box at no extra cost, and as electriccarguide.co.uk notes, its solar matching feature lets you divert surplus generation to your car rather than exporting it to the grid. According to topcharger.co.uk, the Indra is considered one of the best chargers for solar integration.

The Ohme ePod offers Solar Boost and Solar Only modes, giving you the flexibility to either top up solar generation with grid power or charge exclusively from your panels. Both approaches work well, but the Indra's bundled CT clamp is a genuine cost advantage — you won't need to source or pay for one separately.

If you have a 4kW solar array and charge during peak generation, you could realistically add 15–20 miles of range per day for free during summer months. Both chargers handle this well, but the Indra edges it on out-of-the-box solar readiness.

Build Quality and Design

These two chargers couldn't look more different on your wall. The Indra Smart PRO is a more substantial unit at 340 × 240 × 115 mm and around 5 kg, with a tethered 6-metre cable ready to go. It carries an IP54 weatherproof rating and IK10 impact protection — that IK10 rating, confirmed by electriccarguide.co.uk, means it can withstand serious knocks, making it ideal for driveways where it might catch a wing mirror. The RFID lock adds a layer of security if your charger is accessible to passers-by.

The Ohme ePod is astonishingly small — at just 1.48 kg and 230 × 140 × 100 mm, it's barely larger than a paperback book. This makes it the most discreet smart charger on the UK market by a considerable margin. The trade-off is that it's untethered, so you'll need to buy a separate Type 2 cable (typically £100–£200 for a decent 5-metre cable) and find somewhere to store it. Some owners love the flexibility of carrying their cable for destination charging; others find the plug-in-and-go convenience of a tethered unit hard to beat, especially in the rain.

Both units share an IP54 rating, so they're suitable for sheltered outdoor installation, though neither matches the IP67 rating of Indra's premium LUX model.

Installation Considerations

Here's where the Indra Smart PRO claws back significant value. It includes a surge protection device (SPD) as standard — a component that since the 18th Edition wiring regulations is required for most UK EV charger installations. If your consumer unit doesn't already have one, your electrician will typically charge £100–£150 to supply and fit an SPD. With the Indra, that cost is already covered.

The Ohme ePod's installation is quoted from £300–£600, while the Indra sits at £400–£600. However, the Ohme's built-in 3G/4G SIM means it doesn't need Wi-Fi connectivity at the installation location — a genuine advantage if your charger is at the far end of a long driveway or in a detached garage with poor Wi-Fi signal. The Indra relies on Wi-Fi and Bluetooth, so you may need a Wi-Fi extender in some situations.

Both chargers are OZEV-approved, so eligible renters and flat owners can claim up to £500 off installation costs.

Price and Value

On paper, the Ohme ePod looks cheaper — and it is, if your installation is straightforward and you already own a Type 2 cable. But once you factor in a cable purchase and the Indra's included SPD, the real-world gap narrows considerably. For a typical installation, you're looking at roughly similar total costs of around £1,000–£1,100 for either charger.

The value question really comes down to what matters more to you: the Indra's hardware extras (SPD, CT clamp, tethered cable, RFID lock) or the Ohme's software sophistication (deeper tariff integration, cellular connectivity, OTA updates).

Who Should Buy Which?

Buy the Indra Smart PRO if:

• You want a tethered charger with everything included — no extra cables to buy
• Your consumer unit needs an SPD and you'd rather save £100–£150 on installation
• You have or plan to install solar panels and want the CT clamp included at no extra cost
• You value British manufacturing and want to support a UK-based company
• You want RFID security for a charger accessible from a public footpath

Buy the Ohme ePod if:

• You're on Octopus Intelligent Go or Agile and want the deepest possible tariff integration
• You want the smallest, most discreet charger available in the UK
• Your charger location has poor or no Wi-Fi — the built-in 4G SIM solves this completely
• You like the flexibility of an untethered socket and carrying your own cable
• You want the lowest upfront unit cost and already own a Type 2 cable

Our recommendation: For most UK Tesla owners, the Ohme ePod edges it — its tariff integration is genuinely best-in-class, and the annual savings from perfectly optimised smart charging will quickly outweigh the cost of buying a separate cable. The built-in cellular connectivity also means one fewer thing to troubleshoot. However, if you're installing in a location without existing surge protection and you have solar panels, the Indra Smart PRO offers better total value once you account for the included SPD and CT clamp. Both are solid choices — this is a decision between two good chargers, not a case of avoiding a bad one.
