IoT Capability

Device fleets that stay online

T7 Solution builds custom IoT device monitoring and management platforms — provisioning, health, OTA updates, remote control and diagnostics — for fleets from 100 to 1M devices.

Overview

Field devices die silently: bad SIMs, firmware regressions, tampered enclosures, dead batteries. Without a proper device management layer, field ops finds out from angry customers.

We build device management platforms with zero-touch provisioning, live health, OTA firmware updates (staged, rollback-safe), remote diagnostics and end-of-life workflows.

Deployments cover cellular, LoRaWAN, NB-IoT, Wi-Fi and wired gateways — with vendor-agnostic device SDKs and a policy engine for fleet-wide operations.

What we ship

Zero-touch provisioning

Device claims itself on first boot; certificates and config pushed automatically.

Health monitoring

Connectivity, battery, signal, uptime, error rate and tamper — one heartbeat per device.

OTA updates

Staged rollouts with canary, rings, health gates and one-click rollback.

Remote diagnostics

Live logs, config pull, on-demand reboot and remote shell — with full audit.

Policy engine

Fleet-wide rules by device group, region, firmware, tenant — no per-device clicks.

Certificate lifecycle

mTLS certificates issued, rotated and revoked as a first-class flow.

How we're different

Vendor-agnostic

Cellular, LoRaWAN, NB-IoT, Wi-Fi and wired — one platform, not four.

OTA done safely

Canary, staged rings, health-gated promotion and instant rollback — bricking a fleet is not an option.

Certificate-first

mTLS, per-device identity and rotation as a workflow, not a spreadsheet.

Field-ops friendly

Ops teams get bulk actions, saved views and audit — not just device-by-device screens.

Frequently asked questions

How big a fleet can this handle?

Our stack scales from hundreds to a few million devices per tenant with broker clustering and horizontal partitioning.

Which brokers do you use?

EMQX, AWS IoT Core, Azure IoT Hub or HiveMQ — chosen per scale, latency and regulatory profile.

Is OTA rollback automatic?

Yes — health gates auto-halt the rollout and roll devices back if error signals cross thresholds.

Can it handle intermittent connectivity?

Yes — store-and-forward on device, idempotent server ingest and reconciliation on reconnect.
