Put every field device on the SLDC SCADA feed — instantly, and securely.
Wattmon SLDC Bridge is a secure gateway that takes real-time telemetry from your wind, solar or other renewable energy loggers over MQTT and delivers it straight into your State Load Despatch Centre's SCADA system as a fully compliant IEC 60870-5-104 feed — with dual redundant links, mutual-TLS device security, and self-service onboarding for every new site.
One bridge, from field device to grid operator
Modern loggers and inverters speak MQTT and JSON. SLDC's SCADA systems speak IEC 60870-5-104. Wattmon SLDC Bridge sits in between, so neither side has to change.
Every site's data flows continuously to both the primary and backup SLDC masters at once — exactly as mandated, with no manual failover.
Connect a device
Point any MQTT-capable logger at the bridge and publish JSON readings. Wattmon devices work out of the box; third-party devices just need the same simple JSON structure.
Onboard the site in seconds
Assign a Site ID, and the bridge auto-allocates an IEC 104 Common Address from your own reserved range and issues a unique device certificate immediately.
Go live on SLDC's feed
The bridge answers General Interrogation and streams spontaneous updates to both the primary and backup SLDC master, continuously, with no further setup.
Built for how SLDC compliance actually works
Every feature below is a real, running capability — not a roadmap item.
Instant, secure MQTT communication
Mutual TLS on every device connection, a unique certificate per logger, and automatic disconnection the moment any device tries to publish under an identity that isn't its own.
Direct, compliant SLDC feed
A native IEC 60870-5-104 outstation that answers interrogation and streams live values — with simultaneous primary and backup master connections, as SLDC requires.
Effortless onboarding
Self-service site setup with automatic Common Address assignment from a reserved range, and instant certificate issuance — no manual protocol configuration, ever.
Full Wattmon compatibility
Works natively with Wattmon data loggers, and with any third-party device that can publish a simple JSON payload over MQTT.
Multi-site, multi-tenant
A role-based dashboard lets an operator manage dozens of sites directly, or hand self-service control of specific sites to the teams that run them.
Built-in reporting & audit
Download CSV reports for any site and period, built from the exact same data points sent to SLDC — plus live connection and security-event logs for field troubleshooting.
Who it's for
Anyone who has to get real-time generation data to a grid operator without building a SCADA integration team.
meeting SLDC's real-time telemetry mandate across a growing fleet of sites.
managing SCADA compliance for multiple asset owners from one dashboard.
who need a drop-in IEC 60870-5-104 endpoint without building one themselves.
who need new sites to go live in minutes, not weeks of protocol work.
