Monta back-office · default pick

Monta is the most widely used OCPP back-office for small UK commercial and hospitality sites. Smart Wall connects out of the box. Set tariffs in the Monta web portal — per-kWh, per-session, time-of-day tiered, member-vs-visitor pricing. Customers pay through the Monta app or scan a QR on the unit. Settles weekly to your bank account. Typical Monta fee around 7–12% depending on plan tier.

Three authentication methods

RFID tap (cards pre-registered to staff, members, regulars), QR code scan (Monta or other back-office app captures the unit ID and authorises payment), roaming app (Octopus Electroverse, Bonnet, Plugsurfing connect via OCPI to your back-office). Configure all three or just the one that fits your site model.

Tiered tariff structures

Set different rates for different user groups. Staff RFID card: free (charging as a workplace benefit). Member RFID: discounted per-kWh rate. Visitor app scan: full per-kWh rate plus a per-session connection fee. Configurable per RFID group in the back-office without firmware changes — adjust pricing weekly if energy costs change.

Time-of-day pricing

Higher rate during peak demand (evening 4–7 PM matching the grid peak), lower rate overnight (when your business closes and the charger can absorb cheap grid). Useful for sites that want overnight charging by staff at near-cost while charging visitors a premium during business hours. Configured per-tariff in the back-office.

Real-time monitoring

Back-office dashboard shows live session status, monthly revenue, utilisation rate, fault alerts, and energy cost reconciliation against your electricity bill. Critical for hospitality sites where the charger is an amenity — if a customer can't charge, the back-office tells you before the customer complains at reception.

CSV / API session export

Every session exportable — driver ID, RFID, start/end time, kWh delivered, revenue, cost. CSV download for monthly accounting, REST API for automated integration with Xero, QuickBooks, Sage, or custom revenue dashboards. Critical for fleet operators where mileage-and-cost reconciliation must integrate with company-car-tax reporting.

Roaming networks

Monta and most other back-offices include OCPI roaming — your Smart Wall appears on the Octopus Electroverse map, Bonnet network, Plugsurfing, Chargemap. Drivers using any of these apps can charge at your site; the roaming network handles payment and settles to you net of their roaming fee. Useful for sites in destination locations (hotels, restaurants, retail) where casual visitor traffic justifies network exposure.

Whole-site load management

CT clamp on the site's main supply lets the Smart Wall throttle output when other site loads peak. Restaurant kitchen at lunch service, gym fitness class evening peak, office HVAC midday — the Smart Wall coordinates so total site demand stays within main fuse rating. Particularly important for retrofit installs on existing commercial supplies.

Multiple chargers · same back-office

A single Monta or Driivz account supports unlimited chargers. Add a second Smart Wall as your site grows, scale to a Smart Wall Triple 66 kW for higher-traffic sites, or expand across multiple property locations — all on one account, one settlement schedule, one set of tariff configurations. No per-charger account proliferation.

1 · Type 2 socket

IEC 62196-2 socket — the European standard for AC EV charging. Identical to the home Octa Wall socket. Untethered means drivers bring their own Type 2 cable; some commercial sites add a tethered cable option for guest convenience (configurable at order). Seven pins: three live phases, neutral, earth, Control Pilot, Proximity Pilot.

2 · AC supply terminals

Three live phases (or single phase if that's what the site has), neutral, and earth. Wired in copper SWA cable from a dedicated 32 A or 40 A breaker in the commercial consumer unit. Cable size sized to the run length and ambient. Type B RCD typically installed for DC fault protection on commercial premises (built-in 6 mA DC detection on the charger satisfies most installs).

3 · CT clamp · site load

CT clamp on the site's main incoming supply. Measures total commercial load in real time so the charger can adjust output when kitchen, HVAC, gym equipment, or office loads peak. Without the CT clamp the charger runs at fixed maximum rate — fine for sites with plenty of headroom, problematic for retrofit installs on tight 100 A supplies.

4 · 4G LTE module · standard

4G LTE backup is fitted as standard on Smart Wall (optional on the home Octa Wall). Critical for billing: if the site Wi-Fi drops out, the OCPP back-office connection drops, sessions can't authenticate or settle. 4G LTE maintains the back-office link independently of site internet. SIM included; pay-as-you-go top-up via the OCTA app.

5 · OCPP 1.6J endpoint

The unit speaks OCPP 1.6 JSON natively — the industry-standard protocol for EV charger billing. Connects to any compliant back-office via WebSocket. Endpoint URL configured at commissioning. Authentication via API key or certificate. Once connected, the back-office handles all session lifecycle: authentication, metering, billing, settlement.

6 · RFID reader

Mifare Classic and DESFire RFID reader built into the unit. Reads ISO 14443-A cards — the same standard used by hotel key cards, gym membership cards, Transport for London Oyster, and many corporate ID systems. Existing membership cards can often double as charging access cards with back-office configuration, no card reissue required.

ORDER CONFIGURATION
7 · Cable: Tethered vs Untethered

Untethered (Socket) — £1439 total. Customers bring their own Type 2 cable. Flexible for hospitality and gym sites where drivers vary widely; cable lives off the wall when not in use, no maintenance liability for damaged cables. The right pick for boutique hotels, gym member parks, BTR landlord car parks, and most workplace amenity bays.

Tethered (with Cable) — £1439 total. Fixed 5 m or 7.5 m Type 2 cable permanently attached. No friction for customers without their own cable, no risk of cable theft from boot, more professional impression at premium hospitality sites. The right pick for driving instructor businesses (cable always to hand), premium hotels where guest convenience is part of the brand, and dealership demonstrator-handover bays where the customer may not have their own cable yet.

3 year manufacturer warranty

OCTA warrants the Smart Wall for 3 years from commissioning. Covers the unit electronics, the Type 2 socket, the OCPP firmware, the 4G LTE module, and the RFID reader. Extended warranty to 5 years available where the system is on CleverBloom's commercial monitoring service plan. Spare parts hold in UK stock through the distributor channel.

UCP commercial heritage

The same UCP platform runs Smart Wall installations at Volvo, Jaguar, and Land Rover dealership sites — commercial operating intensity proven across years of customer-facing use. The home Octa Wall is the same DNA scaled down; the Smart Wall is the platform in its native commercial environment. Lower failure rates than the consumer-only EV charger brands.

4G LTE redundancy

The 4G LTE backup connection (standard on commercial spec, optional on home) keeps the unit online when site Wi-Fi drops. Critical for billing — every offline hour is sessions that can't authenticate and revenue that can't settle. Site internet drops happen; the 4G fallback means the charger doesn't care.

Workplace Charging Scheme grant

The UK government Workplace Charging Scheme (WCS) provides up to £350 per socket (max £15,000 per applicant) for businesses installing EV charging. The Smart Wall is OZEV-approved and WCS-eligible. CleverBloom submits the application on your behalf as part of the install scope — paperwork handled, grant credited against your invoice.

SYSTEM PROTECTOR
Back-office tariff vigilance

Tariffs that don't track wholesale electricity cost are the silent killer of commercial charger economics. If your business pays 35p/kWh and you charge customers 30p/kWh, you're subsidising EV drivers from your hospitality margin. Review tariffs quarterly against your supplier bill — CleverBloom's commercial service plan includes this review as part of the monthly check.

SYSTEM PROTECTOR
Signage and driver guidance

A charger no driver understands how to use is a charger that loses revenue and frustrates customers. QR code signage beside the bay, brief instructions on how to start a session, contact details for support — these are 60-minute install details that determine whether your utilisation rate sits at 5% or 35% across the first year. CleverBloom installs basic signage as standard.
