Smart Charging Without Internet
100% reliable — even without an internet connection
Access, authentication, configuration, software updates, and billing — all without internet at the charging station. Updates reach the wallbox via users' smartphones. No connectivity needed — ever.
Free ConsultationSecureCharge
Patented offline charging management. Users tap in the app and connect via Bluetooth. Charging data is stored locally and syncs later when connectivity is available.
Bluetooth Authentication
Patented cryptographic protocols verify the user directly at the wallbox via Bluetooth. Instant access — without cellular or Wi-Fi.
Store-and-Forward Sync
Charging data is stored locally and syncs when connectivity is available — via gateway, smartphone, or scheduled transfer. Nothing is lost.
40–70% TCO Savings
No SIM cards, no connectivity fees, no network infrastructure. No more hidden costs eating into operator margins.
100% Reliability
Works in basements where connectivity fails. Every charging session starts, every time — even in the deepest underground garage.
Charge Offline. Pay Online.
Connect via Bluetooth
Users open the app and connect to the wallbox via Bluetooth. No cellular, no Wi-Fi needed.
Authenticate locally
Patented cryptographic protocols verify the user directly at the wallbox. Instant access, always.
Sync automatically
Charging data syncs with the cloud as soon as connectivity is available. Nothing is lost.
Fully managed — even offline
Manage your wallboxes through their complete lifecycle — from commissioning to software updates. Everything works without a permanent internet connection.
Installation & Commissioning
Mount the wallbox, configure via app, and start operating immediately. No network setup, no IT effort.
Daily Operation
Users charge via the Bluetooth app. Consumption data is captured locally and synced when convenient. 100% reliable.
Configuration Changes
Change access rights, load limits, and user groups remotely — updates reach the wallbox at the next user contact.
Software Updates
Firmware updates are delivered to the wallbox via users' smartphones. No technician on-site needed.
Monitoring & Reporting
Consumption, utilization, and status of all wallboxes in the admin panel — complete even with delayed synchronization.
Start Offline. Upgrade to Hybrid Online.
Start purely offline — and add smart online features when you need them. On day one or later. Without replacing wallboxes. And the best part: even in hybrid mode, the app still connects directly to the wallbox via Bluetooth — you keep industry-leading reliability. The best of both worlds.
