Ohme Home Pro vs Indra Smart LUX: Smart Tariff King vs UK-Built Tank
The Tariff Whisperer vs the British-Built Bruiser
If you're shopping for a smart home charger in 2025, you've probably noticed that the market has matured dramatically. Gone are the days when "smart" just meant you could tap a button in an app. Today's best chargers actively save you money, divert solar energy, and shrug off whatever the British weather throws at them. The Ohme Home Pro and Indra Smart LUX represent two slightly different philosophies in this space — and choosing between them comes down to what you value most.
The Ohme Home Pro has carved out a reputation as the go-to charger for drivers on smart energy tariffs, particularly Octopus Intelligent Go. It's the charger Octopus Energy themselves recommend, and its deep tariff integration is genuinely best-in-class. The Indra Smart LUX, meanwhile, is a proudly UK-designed and manufactured unit from Worcestershire that leads on build quality, with the slimmest profile and toughest protection ratings of any home charger on the market. Both are 7.4kW tethered units with solar diversion and smart tariff support — so the devil really is in the details.
In a nutshell:
- Ohme Home Pro (£535): The undisputed champion of smart tariff integration, with built-in 4G and Octopus Intelligent Go optimisation that can cut your charging costs to as little as 7p/kWh.
- Indra Smart LUX (£615): The UK's slimmest smart charger with tank-like IP67/IK10 protection and integration with over 1,000 energy tariffs — built for exposed installations and drivers who want maximum durability.

Smart Tariff Integration
This is where the Ohme Home Pro truly shines — and where the comparison gets interesting. The Ohme is officially recommended by Octopus Energy for their Intelligent Go tariff, which offers electricity at roughly 7p/kWh during off-peak hours. The charger doesn't just schedule charging during cheap windows; it communicates directly with Octopus's platform via API, meaning Octopus can dynamically extend your off-peak window and the Ohme responds automatically. As viablepower.co.uk notes, the Ohme can even postpone charging if energy prices spike unexpectedly, always hunting for the lowest rate without you lifting a finger.
The Indra Smart LUX takes a broader approach, claiming integration with over 1,000 UK energy tariffs including Octopus Agile's half-hourly variable pricing. That breadth is impressive and means you're unlikely to find yourself on an unsupported tariff. However, it lacks the same depth of direct partnership that Ohme enjoys with Octopus — that "recommended by" endorsement matters because it unlocks features like extended off-peak windows that other chargers simply cannot access.
For a driver on Octopus Intelligent Go — arguably the best EV tariff in the UK right now — the Ohme's advantage here is decisive. If you're on a different tariff or prefer Agile's variable pricing, the Indra's wider compatibility narrows the gap considerably.
Build Quality and Design
The Indra Smart LUX wins this round convincingly. At just 78mm deep, it's the slimmest tethered smart charger on the UK market — noticeably thinner than the Ohme's 100mm depth. Mounted on a wall, the difference is visible: the Indra sits almost flush, which matters if your charger is on the front of your house rather than tucked away in a garage.
More importantly, the Indra boasts IP67 and IK10 ratings. IP67 means it can survive temporary submersion in water — not just rain and jet washing, but genuinely extreme conditions. IK10 is the highest impact resistance rating available, meaning it can withstand 20 joules of impact energy. The Ohme's IP65 rating is perfectly adequate for outdoor UK installations (it handles rain and dust without issue), but if your charger is in an exposed coastal location, a busy driveway where it might get knocked, or anywhere particularly harsh, the Indra's protection is in a different league.
The Indra also comes with built-in SPD (surge protection device) and PEN fault detection as standard, which can simplify installation and potentially reduce your electrician's bill. The Ohme counters with its colour LCD display — a genuinely useful feature that shows real-time charging status at a glance without needing to open an app. The Indra uses a turbine-style LED indicator instead, which looks elegant but conveys less information.
App and Connectivity
Here's a critical difference that could swing your decision. The Ohme Home Pro includes built-in 4G connectivity with a 3-year SIM card in the box. If your Wi-Fi signal doesn't reach your driveway — a surprisingly common problem in UK homes, as evenergyhub.com highlights — the Ohme keeps working perfectly via mobile data. Your smart tariff scheduling, solar diversion, and app control all function regardless of your router situation.
The Indra Smart LUX relies on Wi-Fi as standard. If you need 4G backup, it's available — but at an eye-watering £250 extra. That's nearly half the price of the charger itself, and it pushes the total cost well above the Ohme. Ethernet is also available as an option for the Indra, which could be a practical alternative if you can run a cable, but most installations won't have that luxury.
Both apps offer energy tracking and session-by-session cost breakdowns. The Ohme app is widely praised as one of the most powerful in the UK market mcnallyev.uk, with detailed savings reports that show exactly what you've saved compared to standard rates. The Indra app supports OCPP 1.6, RFID and QR code authorisation, and remote locking — features that are more relevant if you're sharing the charger or want additional security.
Solar Diversion
Both chargers support solar PV diversion, making them solid choices if you have panels on your roof. The Indra includes a CT clamp in the box for monitoring your solar generation and diverting surplus energy to your car rather than exporting it to the grid. The Ohme also offers built-in solar diverting capability. In practice, both will achieve the same goal: topping up your Tesla with free sunshine during the day, then switching to cheap off-peak grid power overnight. Neither charger has a clear advantage here — it's a draw.
Price and Value
| Cost Element | Ohme Home Pro | Indra Smart LUX |
|---|---|---|
| Unit price | £535 | £615 |
| Typical installation | £400–500 | £300–500 |
| Total installed (estimate) | £935–1,035 | £915–1,115 |
| After OZEV grant (if eligible) | £435–535 | £415–615 |
| 4G connectivity | Included (3-year SIM) | +£250 |
| 5-year warranty | Not available | +£100 |
On paper, the Indra's lower installation estimate (from £300) partly offsets its higher unit price, thanks to built-in SPD and PEN fault detection reducing the electrician's work. However, if you value 4G connectivity — and you should if your Wi-Fi is patchy — the Ohme delivers it for free while the Indra charges £250 extra. Add 4G to the Indra and you're looking at £865 before installation, versus £535 for the Ohme. That's a significant gap.
The Ohme also comes with a longer standard cable on the Indra (6m vs 5m), though the Indra offers a generous 10m option. If you need a long cable run to reach your parking spot, the Indra's 10m version could save you the cost of a cable extension.
Who Should Buy Which?
Buy the Ohme Home Pro if:
- You're on Octopus Intelligent Go (or planning to switch) and want the deepest possible tariff integration
- Your Wi-Fi doesn't reliably reach your charging point — the included 4G SIM is a genuine lifesaver
- You want a colour display showing real-time charging status without opening an app
- You prefer to keep costs down — it's £80 cheaper at the unit level and includes 4G for free
- Detailed cost-per-session tracking and savings reports appeal to your inner accountant
Buy the Indra Smart LUX if:
- Your charger will be in an exposed or vulnerable location — IP67/IK10 protection is unmatched
- You want the slimmest possible profile on your wall (78mm vs 100mm)
- You value UK design and manufacturing — the Indra is built in Worcestershire
- You need a longer cable — 6m standard with a 10m option beats the Ohme's 5m
- You're on a niche energy tariff — support for 1,000+ tariffs means you're almost certainly covered
Our recommendation: For most UK Tesla owners, the Ohme Home Pro is the smarter buy. Its unrivalled Octopus Intelligent Go integration, included 4G connectivity, and lower price make it the charger that will save you the most money over its lifetime. At 7p/kWh on Intelligent Go, you're looking at roughly £2.85 to add 100 miles of range to a Model 3 — that's the cheapest motoring available in the UK today. However, if your charger is going on an exposed wall, a busy commercial forecourt, or anywhere it needs to survive serious weather and knocks, the Indra Smart LUX's tank-like build quality justifies the premium. It's a brilliant charger — it just faces stiff competition from the Ohme's unbeatable tariff savings.
