From Data to Energy Management

How QLines works: energy systems, IoT and SmartHome devices, and bills and meter readings feed the two QLines products. EnergyOS covers energy data analysis, energy management and connected devices; UtilityControl covers consumption analytics. Both are used in the web browser, in the iOS app and in the Android app. Energy systems IoT and SmartHomedevices Bills and meter readings EnergyOS Energy data analysisEnergy managementConnected devices UtilityControl WebiOSAndroid Energysystems IoT andSmartHome Bills andreadings EnergyOS Energy data analysisEnergy managementConnected devices UtilityControl WebiOSAndroid

Sample figures for an example single-family house (150 m², 20,000 kWh gas and 4,000 kWh household electricity a year). Prices per kWh: gas 11 ct, electricity 32 ct, heat pump tariff 27 ct, feed-in 7.7 ct. CO₂: 0.20 kg per kWh gas, 0.38 kg per kWh grid electricity. Lifecycle cost = investment + 20 years of energy cost at constant prices. Not a quote: a real report uses your building's data.

FAQ

Questions

What is QLines Energy Intelligence?

A platform that connects three steps: analyzing building and consumption data to plan measures, managing devices and energy systems remotely, and comparing predicted with measured results to improve them.

How do I try it?

EnergyOS and UtilityControl each have a free plan and are open for sign-up, no credit card required. For Energy Intelligence projects, request a meeting.

Which devices and protocols are supported?

IoT and SmartHome devices with the lightweight QLines agent, and inverters, heat pumps, batteries, EV chargers and smart meters through Modbus, SunSpec, EEBus, OCPP, M-Bus and SML or DLMS/COSEM. Partners integrate through a REST API over HTTPS.
