Industrial telemetry on your own infrastructure

ctrl32 telemetry collects measurements from devices, PLCs and gateways, stores every value as a verifiable record and turns the data into alarms, reports and exports. Self-hosted, multi-tenant and free of charge for every deployment.

Connectivity
MQTT over TLS with per-device tokens, HTTP, LoRaWAN through ChirpStack and OPC UA polling of PLCs and servers. Client libraries for Arduino, ESP-IDF and STM32.

Device management
Provisioning with claim codes, firmware campaigns with rollback, remote console, commands with acknowledgement and shared attributes.

Records you can prove
Append-only observations with device and server timestamps, gap detection, a hash-chained audit trail and integrity-checked exports.

Alarms and reports
Warning and action limits with hysteresis, e-mail notification, CSV and JSON Lines exports and PDF reports built from blocks or your own templates.

Organizations and access
Separate tenants on one server, roles and permissions, two-factor authentication, 19 languages, your logo and colours.

Operations
One-command installer for Linux and Windows, TLS, WireGuard for devices, backups, updates and server settings from the UI. The data stays with you.
