What it does
Small device, whole site.
- Reads any vendor: meters, analysers and sensors over Modbus/RS485, directly or through protocol and signal converters.
- Edge computing: firmware built for energy, utilities and environment metering: analysers, flow and concentration calculators.
- Decentralised: independent of the site's gateways, controllers, hubs, IT and cabling. The main monitoring path on site.
- Open: works with BOX2M OS or any MQTT platform.
- Secure: “Falx class” local security mechanism; provisioned and tested with the BOX2M Build & Test platform.
- Grey-label: produced under your brand on request.
