CHESTER
Stop losing revenue to unmonitored equipment, spoiled inventory, and compliance gaps. Deploy industrial IoT monitoring in days - not months - with a platform that survives -40 to +85 degrees.
Where other IoT platforms fall short
Vendor Lock-in
Closed firmware you can't inspect or modify. You're stuck on the vendor's roadmap.
Slow Time-to-Field
Building from scratch on a bare MCU takes 6-12 months before first deployment.
Fragmented Stack
Sourcing parts separately creates integration risk and finger-pointing when something fails.
Not Field-Ready
Consumer-grade electronics fail in industrial conditions - condensation, vibration, extreme temperatures.
Three steps to your first deployment
Pick or Configure
Choose from 15+ catalog applications or customize with our open SDK. We help you match the right configuration to your use case.
Deploy in Days
Install CHESTER on-site with zero infrastructure. Battery-powered, cellular-connected - no wiring, no gateways, no IT tickets.
Monitor and Scale
See data in HARDWARIO Cloud within minutes. Set alerts, integrate with your systems via REST API, and scale from pilot to thousands of devices.

Where It Works
Cold Chain Compliance
Continuous temperature monitoring for pharmaceutical storage, cold rooms, and food warehouses. Audit-ready records for GDP and HACCP compliance.
Grain Storage Monitoring
Early detection of temperature anomalies in silos and storage facilities. Prevent spoilage worth thousands with real-time hotspot alerts.
Machine Activity Tracking
Non-invasive current monitoring reveals machine utilization, cycle times, and unplanned downtime across your production floor.
Energy Sub-Metering
Track energy consumption at circuit level across buildings and portfolios. Identify waste, validate ESG targets, and reduce costs.
Smart City Infrastructure
Weather stations, flood monitoring, and waste level tracking for municipalities. Battery-powered and LPWAN-connected for city-wide coverage.
Indoor Air Quality
Monitor CO2, temperature, and humidity in schools, offices, and warehouses. Improve occupant comfort and meet ventilation regulations.
