Sfella Legionella Prevention


IoT Device Management Platform – Van Mierlo Engineering

The challenge

The key to preventing Legionnaires’ disease is regular flushing of water systems. Public showers in sports centres, swimming pools are used irregularly and therefore run a higher risk. Monitoring temperature and flushing frequency is critical and is mostly done manually. The challenge for van Mierlo Engineering was to build a cost effective solution which can be installed easily and runs independently, while actively monitoring your different locations remotely and if needed even flush remotely.

Local independent flushing

Severinus care institute upgraded the existing pool showers with van Mierlo’s Sfella system. The location manager can set flush frequency and temperature limits. The Sfella enabled showers are monitored and controlled independently on location, using OpenRemote’s IoT Edge Gateway software. Alerts can be set for the manager to receive notifications in case of abnormal behaviour and the mobile application even allows for remote flushing.

Manage multiple sites

The Severinus care institute can manage multiple locations, either pool showers or related facilities. The central dashboard, delivered and hosted by van Mierlo allows for live reporting as well as receiving alerts for critical situations. If needed showers can even remotely be activated. A centrally hosted OpenRemote IoT platform is connected to the different OpenRemote Edge Gateways.

Alerting & Control

Risk of Legionella growth is anticipated, using OpenRemote’s rules and notifications feature on either the Local Sfella system or in the Central Dashboard. It sends alerts to the respective service organisations if automated flushing has not been activated locally. A remote flush can override the local system, even automatically.

Connected Sources

Local showers act as independent systems. Showers connect via a wireless mesh network to a Sfella Controller in each building. The controller includes OpenRemote’s Edge Gateway software. The Sfella Controllers are connected to the Central cloud based OpenRemote manager, which allows remote access, control, automation and reporting for multiple locations of the health care institute.

IoT Device Management for Manufacturers

Managing IoT devices can become complex for manufacturers distributing large numbers of products to customers, whether for your installer, distributor or service manager.

The OpenRemote IoT Device Management platform connects and controls different all your devices, using auto provisioning combined with MQTT broker, or its Edge Gateway. More importantly, alerts are set to monitor optimal performance as well as unexpected behaviour. Notifications are send to installers or end users to take action.

A dashboard for you as manufacturer, and mobile apps for installers and end users. All can be tailored to your specific context and identity, and hosted in your own secure environment.
