ista provides real-time temperature data, allowing you to ensure comfort, optimize heating efficiency, and respond quickly to deviations without unnecessary service visits.
With real-time temperature data at room level, administrators can quickly deal with complaints and deviations. The solution integrates with other ista devices, supports data-driven energy management, and increases the efficiency of heating systems.
Balanced heating, high comfort, and fair energy management with documented temperature measurements.
Provide tenants with comfort and transparency.
Verify complaints quickly with transparent temperature data.
Manage multiple buildings remotely with one system that ensures comfort and energy efficiency.
The ista T‑Logger measures room temperature with high precision and sends data directly to the administrator via radio.
When a resident reports a temperature problem, the administrator can immediately check the measurements and see if the temperature is within the expected range.
The result is fewer unnecessary interventions, higher resident satisfaction, and consistent energy consumption across the building, with lower costs, better efficiency, and increased comfort for all parties.

Our room temperature monitoring provides accurate measurements and documents whether the heat level is within the legally required comfort range. This means fewer unnecessary inspections – and instead clear insight and efficient administration.
Our room temperature monitoring measures ambient temperature in each room where a device is installed and transmits the data via radio. Managers can access this information remotely, allowing them to verify comfort levels and detect potential heating inefficiencies without on-site inspections.
Yes. Our room temperature monitoring is fully compatible with ista’s metering ecosystem, including heat cost allocators, heat meters, and data collection systems. This ensures seamless integration for a complete, data-driven energy management solution.
The monitoring devicesare equipped with a long-life battery that lasts up to 12 years, ensuring reliable operation and minimal maintenance.
Yes. All temperature data is transmitted wirelessly and can be accessed remotely, allowing managers to monitor comfort levels in real time — without manual readings or site visits.
Temperature data is primarily available to administrators or facility managers to support system optimisation and resolve comfort complaints. However, transparent reporting ensures that residents are informed about indoor comfort levels.
Absolutely. Ista's monitoring devices meet all relevant Danish and EU MID standards, ensuring accuracy, safety, and compatibility.
While specific temperature monitoring in every apartment is not currently mandatory, upcoming regulations will require advanced building management systems to continuously monitor indoor climate data from June 2026.
