SmartPuls gives your PLC access to electricity prices, temperature, and precise time – without network connections, API integrations, or complex setup.
What is the box?
SmartPuls is a small unit mounted directly on the DIN rail inside the electrical panel.
It has a built-in SIM card and automatically delivers data to your control system – without the need for network access, IT involvement or complex setup.
All communication takes place via a single 24VDC digital output, which is connected to a PLC input.
This makes the solution simple to install and easy to use in existing automation systems.
With SmartPuls, you can easily start and stop equipment, optimize operation and document energy consumption – fully automatically.
Electricity prices in 15-minute intervals – today and tomorrow
Weather data for the local location via GPS – hour by hour, today and tomorrow
CO₂ intensity in g CO₂/kWh every 5 minutes – for display in SCADA and documentation in ESG reporting
Current time – used as a precise time server
Error signal in case of missing data
Simple, secure and NIS2-compatible data delivery

That is roughly equivalent to a passenger car driving almost twice around the world.
Payback is based on SmartPuls Complete 4G at 5.450 kr. plus 12 months of subscription at 99 kr./month — excl. VAT.
CO₂ estimate based on an assumed difference of 50 g CO₂/kWh between high- and low-price periods — the actual difference varies over time.

Retrieves electricity prices, weather data, CO₂ data and time from external data sources.
Converts the data into a simple digital signal.
The PLC receives the signal through a digital input.
The data is displayed and used for control, alarms and optimisation.
SmartPuls delivers external data to PLC and SCADA — without direct network access to the automation system.
Installation in practice
Simple installation in the control cabinet
SmartPuls is mounted directly on the DIN rail and connected to the PLC through one 24 VDC digital signal.
The built-in 4G connection means no network access to the automation system is required.
Direct DIN-rail mounting
One 24 VDC digital signal to the PLC
No network access to PLC or SCADA
Suitable for both new installations and integration into existing control cabinets.
Examples from different plant types
See how SmartPuls can be used in district heating, biogas and wastewater applications.
Start and stop electric boilers and heat pumps based on electricity prices — reduce operating costs during high-price periods.
Dynamic load control: Scale heat pumps, pumps or electric boilers in steps according to price level, e.g. 100% / 50% / 0%.
Electricity consumption logging: Get an accurate picture of when and how much electricity is used — and what it costs.
Accurate electricity cost calculation: Combine operating times and electricity prices to analyse the efficiency of individual machines or processes.
Automatically switch between heat-producing units based on electricity prices — for example between heat pumps and gas or wood-pellet boilers.
Time-based operation: Synchronise the PLC with an accurate clock — important for scheduled switching and documentation.
Temperature-based control: Adjust heat-pump start, stop and load steps according to both price and outdoor temperature.
Gas engine control: Start and stop gas engines based on current electricity prices and maximise the economics of power generation.
Compressors and pumps: Optimise operating times for energy-intensive equipment — run during low-price periods and avoid high-price periods.
Gas storage: Delay the use of stored biogas until periods with higher electricity prices, when generation provides the best return.
Time-controlled PLC operation: Synchronise the PLC system with the built-in time server and avoid deviations in control logic.
Automated energy management: Activate functions automatically during low-price periods — without manual intervention.
Tank mixing: Reduce or postpone mixing during high-price periods where the process allows it — and save energy.
Weather-compensated operation: Use local temperature data to adjust strategies such as gas-engine loading or heat recovery.
Pump control: Adjust pumping in sewer systems and pumping stations according to electricity prices and postpone non-critical pumping to low-price periods.
Mixing and aeration: Run aeration tanks and mixers more intensively when electricity is cheap and reduce operation during high-price periods.
Sludge dewatering and transport: Schedule dewatering, polymer dosing and sludge pumping during low-price periods.
Carbon filters and UV systems: Adjust operating times for UV disinfection and carbon filters where operationally appropriate.
Heat pumps: Optimise wastewater-based heat-pump operation according to price level and reduce energy costs.
Temperature-controlled aeration: Adjust mixer and aerator operation based on water temperature and outdoor temperature.
