Industrial IoT (IIoT): from sensor to cloud
End-to-end IIoT systems from hardware to cloud: ESP32 edge nodes, Modbus and MQTT, Docker servers, safe OTA updates and predictive maintenance. A live example: HS-IIoT.
Most facilities here run good equipment that is silent: nobody knows what is happening unless they are standing in front of it. I build the layer that makes it talk: an edge node that reads and filters, a secure link, a server that stores, and a dashboard that warns before the failure. HS-IIoT was built exactly this way, from hardware to cloud.
What I do
Connecting existing equipment
Adding monitoring to existing generators, panels and pumps over Modbus and RS485 without modifying them.
Server and cloud
Docker, MQTT, MongoDB, Node-RED and WireGuard tunnels, on your server or in the cloud.
Reliability and predictive maintenance
Safe OTA updates with automatic rollback, and load-unbalance analysis that predicts faults before they happen.
Standards

FAQ
What is the Industrial Internet of Things (IIoT)?
Connecting industrial equipment and sensors to a network that collects and analyses their data, so you know the state of the facility in real time and act before failures. It differs from consumer IoT in its reliability, security and harsh-environment requirements.
Can old equipment be connected to a monitoring system?
Usually yes. Most generators, meters and panels have a Modbus port or can take external sensors, then connect to an edge gateway without modifying the equipment.
Where is the data stored?
On a server inside your facility or in the cloud, as you prefer. Either way the data travels through an encrypted tunnel.
What happens when the internet drops?
The system is designed so the edge node keeps working locally and local control never depends on the internet; data flows again when the link returns.
