Per-item results
A batch never fails silently: each reading is accepted, flagged as duplicate, or rejected with a reason such as unknown sensor or timestamp in the future.
Technology
- IIoT
- SSE
- RFC 8628
- Tenant isolation
Industrial IoT, built to be trusted at the asset.
Hydris is a multi-tenant platform: edge gateways push telemetry over HTTPS, the platform validates and evaluates it, and a realtime stream delivers exactly the right context to the console and to each pair of glasses.

Idempotent & ordered
Message IDs make retries safe; out-of-order readings are stored by observation time, not arrival time.
Alarm evaluation
High, high-high, low and low-low rules with deadband hysteresis and on-delay, evaluated as readings land.
/02Context awareness
The right context for the right operator.
- Who
- One operator per device at a time. Reassignment clears the previous operator’s context and is audited.
- Where
- Only the sites and areas the operator is permitted for; events from other sites are never delivered.
- What
- The assets on the current round, their latest readings with freshness, open alarms and approved documents.
- When
- Values age visibly: live, delayed, stale, no data. A frozen number never masquerades as a healthy one.
/03Device pairing & identity
Pairing modelled on the device authorisation grant (RFC 8628).
Glasses have no keyboard, so they never handle a password. The QR code carries no reusable credential; challenges are single-use, expire after five minutes and are rate-limited against guessing.
- 01
Glasses request a challenge
The device asks for a pairing challenge and receives a short user code plus a separate device secret that is never displayed.
- 02
QR + 8-character code
The viewport shows XXXX-XXXX and a QR link. The alphabet avoids look-alike characters (no 0/O, 1/I/L).
- 03
An authorised person approves
Signed in to the console on another device, they confirm the code and assign the glasses to an operator and sites.
- 04
Device claims its credential
The glasses poll (no faster than every 3 s) and, once approved, exchange their secret for a short-lived device credential.
Lifecycle: unregistered → pending pairing → paired → assigned → connected / disconnected. Any device can be suspended or revoked from the console.
/04Offline-capable sync & realtime
Dead spots are part of the plant.
Degraded mode, stated plainly
When the network drops, the viewport says so and every value shows its age.
Local step queue
Inspection responses queue on the device and sync in order on reconnect.
Server-Sent Events
One long-lived HTTPS stream per client, with the token in a header — never in the URL.
Replay after reconnect
Last-Event-ID replay closes gaps; sessions are re-validated every 30 s so revoked devices are disconnected.
Safety & reliability
Advisory only. Hydris never actuates pumps, valves or dosing.
Advisory only
No write path to SCADA, PLCs or field devices. Hydris shows context and records observations; operators act through your existing controls and permits.
Tenant isolation
Every query runs in the caller’s organisation context, enforced in the database. Realtime events are authorised per connection.
Audit trail
Pairing approvals, device assignments, alarm actions, inspection reviews and permission changes are recorded with who and when.
Least privilege
Role- and site-scoped permissions. Devices get their own short-lived credentials and only see approved documents.
Session tokens
Short-lived access tokens held in memory; refresh tokens are httpOnly, SameSite=Strict cookies and rotate on use.
Gateway keys
Per-site gateway keys are stored as hashes and can be revoked instantly from the console.
Synthetic data separation
Simulator data is only accepted in demo tenants and is labelled synthetic wherever it is shown.
Account provisioning
Accounts are invited by an administrator; there is no self-registration into a customer tenant.
/05Integrations
What connects today, and what is planned.
| Integration | How it works | Status |
|---|---|---|
| Edge gateway → HTTPS ingestion | JSON batches (≤ 500 readings) with a per-site API key; per-item accept / reject results; idempotent by message ID. | Available now |
| Manual & laboratory entry | Field and lab results entered in the console with source and timestamp provenance. | Available now |
| Realtime stream (SSE) | Server-Sent Events to console and glasses, authorised per connection, Last-Event-ID replay. | Available now |
| History export | Per-sensor history and CSV export for reporting and regulator submissions. | Available now |
| MQTT adapter | Edge adapter subscribing to existing broker topics and forwarding to ingestion. | Planned |
| OPC UA adapter | Edge adapter reading tags from OPC UA servers. | Planned |
| Native glasses adapter | Device packaging for Meta Ray-Ban Display class glasses; today the viewport runs in a browser. | Planned |
/06Future: computer vision & more
Computer vision is planned — and labelled that way.
We are exploring gauge reading and visual anomaly prompts from the glasses camera. Any such feature will suggest, never decide: the operator confirms what is recorded. None of it is available today.
Available now
In this release- Glasses viewport (web) + browser simulator
- Live asset context with data freshness
- Guided inspections, rounds & maintenance checklists
- Alarm rules with deadband and on-delay
- Approved SOPs for operators and devices
- QR + short-code device pairing, fleet management
- HTTPS edge-gateway ingestion, manual & lab entry
- Realtime (SSE), audit trail, CSV export
Planned
Not yet available- Computer visionGauge reading and visual anomaly prompts from the glasses camera — always confirmed by the operator.
- VoiceHands-free notes and navigation for gloved, wet work.
- Predictive maintenanceEarly warnings from vibration, motor current and runtime trends.
- MQTT & OPC UA adaptersEdge adapters so existing brokers and servers can feed Hydris without custom code.
- Native device adapterPackaging the viewport for Meta Ray-Ban Display class glasses with neural-band input.
Planned items describe direction, not committed delivery dates. We will tell you plainly what exists when you evaluate Hydris.
Talk to an engineer, not a script.
A 30-minute walkthrough: the glasses viewport, the operator console and how your gateway telemetry would reach both. We will be clear about what is available today and what is planned.
