How It Works
Terminal. Base Station. Skills.
Terminal
Field I/O at the sensor. 4-20 mA and 0-3.3 V analog inputs, dry contact via relay, and an H-bridge output for valves and motor control. Wireless to the Base Station — no trenching, no SIMs.
Base Station
An on-site ARM64 server, one per site, running the full stack: dashboards, alerting, historian, user accounts (RBAC), and audit log. No cloud dependency. Open egress over MQTT, REST, and Prometheus; Modbus TCP integration here.
Skills
Vertical application plugins that turn raw telemetry into operational outcomes. CIP Monitoring for water treatment, Irrigation Intelligence for agriculture. From $20 per Terminal per month, billed annually.

Why Self-Hosted
Running entirely on your site.
Your data never leaves the site.
Single-tenant, on-premise. No telemetry, no phone-home. The Base Station runs the full stack on your hardware, on your network — nobody else sees it.
No subscription hostage.
Skills degrade, they do not disable. If a license lapses, the Skill goes read-only and your sensors keep reporting. The platform never bricks.
Works air-gapped.
Deploy with no internet at all. AES-128 encryption on the LoRa link, TLS on the web UI, JWT with RBAC and an audit log throughout.
See it running on your equipment.
