What goes where
ET-Cloud has separate public, customer, device, and admin parts. This keeps customers away from backend controls while devices keep using native MQTT.
Marketing, service overview, pricing contact, and links to customer portals.
Customer-safe MQTT setup details, topics, device usernames, and support information.
ESP32, ET-Bus, and field devices connect here using MQTT over TLS.
The admin dashboard stays off Cloudflare and is used only by Electronicstech.
Built for real installs
ET-Cloud keeps the customer experience simple while the private backend handles broker setup, certificates, device onboarding, Home Assistant discovery, and operational checks.
Devices connect to a managed broker endpoint with per-device credentials and isolated topic paths.
ET-Bus devices can be published into Home Assistant with discovery, availability, telemetry, and commands.
Each customer gets a clean portal page with broker details, topics, setup steps, and support details.
Managed MQTT for small IoT fleets
Start with pilot devices, then scale by customer, site, and device. The public site can go on Cloudflare; the admin app remains private on the LAN.
