The future in System Monitoring and Data Collection

The Listo:Portal is an intuitive Web Interface that manages storage of collated data on the 'Listo:Portal Cloud'. Information is harvested by our intelligent Interface Modules or customer equiment and transmitted to the cloud. 'Alarm' notifications are forwarded by E-mail or SMS to recipients; 'Events' such as Alarms and pump status changes are logged on the portal for historical reporting.

Stored data such as logging and status information can then be securely viewed via the internet on any web-enabled device to allow user-friendly real-time observation and interrogation of information. The system offers users full control of numerous settings via the portal including but not limited to:

  • Interface Module Setup/Disable
  • Running set Points
  • Event Logging Configuration
  • Alarms Notification Configuration
  • Override On/Off of individual Event logging & Alarm notifications
  • Run reports to screen and CSV file download/export

Through an intensive R&D programme and end-user collaboration we have designed a comprehensive yet straightforward viewing platform for all our customers. Listo offers complete hardware, software and support packages for monitoring, control and reporting systems.

Listo design and manufacture our own PCBs, enabling us to build a catalogue of dedicated hardware and supplementary products to interface with Customers' existing equipment to ready data available for collection and upload to our Listo:Portal cloud servers. With on-going development, support and continuing system upgrades we offer a fully future-proofed monitoring and reporting package for the end-user.

Listo:Portal Features

Monitoring of Signals

Any measured variable can be collected, either automatically or manually from entry to the web page or from spreadsheets.

Equipment Status

Any equipment with digital status can be logged, either as an event or alarm condition.


Critical readings can be displayed as highly visual clear dial gauges with coloured sections to highlight out-of-tolerance readings.


All water qualities, power usage, and water usage logged can be viewed as trends or tabular data. The data can be filtered to display the latest data or back into history to track any events.


Equipment service history can be logged. Allowing for running hours, for example pump running time or UV bulb running time. Events can be set to trigger messages for service intervals. Water quality calibration readings can be stored to give a history of probe calibrations.

SMS / Email Alarm

Measured values, equipment status and service events can be either emailed or sent as SMS messages. The system will repeat the messages at a user defined interval until the alarm condition has been acknowledged.

Utility Usage

Water, gas, air usage can be monitored to track usage. Costings per unit can be entered into the system to give the usage as an actual cost.

Downtime Escalation

When monitoring production lines the system can contact different levels of management over a period of time to escalate the fault.

Power Monitoring

Site power can be monitored to allow for costs to be allocated to separate plant sections. Changes in power usage can be highlighted and the system can be used to monitor power saving changes for benefits. Costings per unit can be entered into the system to give the power usage as an actual cost.
