Platform

Everything your device needs.
Nothing you have to build.

PumpLink handles the infrastructure. You handle the hardware.

Remote activation

Turn any connected device on or off from anywhere. Set a duration and it stops automatically — no manual intervention required.

Scheduling & recurrence

Schedule one-off or recurring activations days in advance. The scheduler fires reliably even after server restarts, skipping missed ticks rather than bursting.

Multi-user access

Invite your whole team. Assign roles. Revoke access instantly. Users are always free — you only pay for devices.

Full audit trail

Every activation logged with who triggered it, when, and for how long. Nothing happens invisibly.

Per-device security

Each device gets its own MQTT credentials. Topic-level ACL ensures device A cannot touch device B's topics — enforced at the broker layer.

Device status

Check whether each device is on, off, or mid-activation, right from the dashboard.

Daily runtime limits

Set daily runtime limits independently per device. Quota state persists across server restarts — no silent resets, no surprise overruns.

Push notifications

Get notified when a device activates, completes, goes offline, or hits its quota limit. Stay informed without watching a dashboard.

Multi-tenant

Complete tenant isolation. Each organisation sees only their own devices, users, and logs. Built for teams and businesses from day one.

Device access control

Assign specific devices to specific users. Control exactly which team members can activate, schedule, or view each device in your fleet.

Integration

Connected in under 30 minutes.

No custom backend required. Wire your hardware to PumpLink and get everything else out of the box.

Create your account

Add your device in the dashboard. PumpLink generates unique MQTT credentials scoped to that device only.

Flash the starter firmware

Clone our ESP32 firmware repo, paste in the credentials from step 2, and flash. Once it boots and connects to the broker, it's ready to receive activation commands.

Control from anywhere

Activate on demand, schedule in advance, or let your users control their own devices — through the web dashboard or the iOS app.

Pricing

Pay for devices. Users are always free.

Start free. Upgrade when your fleet grows. No per-seat fees, ever.
