Smart building energy management: how EnerGroup enabled wireless room-level heating control with ThingsBoard

EnerGroup is a Swiss energy and automation integrator specializing in smart building technologies, energy renovation projects, and IoT-driven supervision platforms. The company supports residential and commercial building owners in reducing energy consumption, improving occupant comfort, and gaining full visibility into their technical installations.

EnerGroup delivers end-to-end solutions covering renewable energy production, heating and domestic hot water systems, building automation (MCR), IoT connectivity, and digital supervision through its proprietary platform EnerMon, built on ThingsBoard.

With a strong focus on real-world renovation constraints, EnerGroup emphasizes scalable, open, and non-intrusive solutions that can be deployed in both new and existing buildings.

What problem did they face?

Challenges

Before the renovation, the Pyxis residential building faced several challenges.
Decentralized electric domestic hot water systems in each apartment, resulting in high energy consumption.
No centralized monitoring or control of heating and energy usage.
Limited visibility for the building operator.
Constraints related to renovation works in occupied apartments.
Lack of flexibility for future optimization.

Key results

Centralized renewable heat and DHW production using heat pumps.
Wireless room-level heating control without intrusive cabling.
Improved comfort for tenants with individual temperature control.
Centralized supervision of technical and energy systems.
A scalable digital foundation for future optimization and analytics.

How ThingsBoard powers the EnerGroup?

Wireless room temperature monitoring

Energroup deployed battery-powered Milesight WT401 thermostats in every room of each apartment. These devices continuously measure room temperatures and transmit data via LoRaWAN to the backend systems. ThingsBoard collects, stores, and visualizes this data, enabling real-time monitoring and historical analysis.

Heating loop control via LoRaWAN actuators

At the heating manifold level, Milesight WS558 actuators were installed to control individual heating loops. ThingsBoard manages the bidirectional communication between room demand and hydraulic actuation, ensuring precise and responsive temperature regulation across the building.

Centralized supervision with EnerMon

Energroup uses EnerMon, its branded platform based on ThingsBoard, to provide a unified view of the entire installation. The platform aggregates data from heating systems, domestic hot water production, and energy sources, offering both tenant-level interfaces and operator dashboards.

Secure and scalable IoT infrastructure

ThingsBoard is deployed on a dedicated server and integrated with a ChirpStack LoRaWAN Network and Application Server hosted by Energroup. This architecture ensures data security, high availability, and independence from proprietary cloud ecosystems.

How ThingsBoard helps smart buildings improve operations with IoT

Custom dashboards

ThingsBoard dashboards provide intuitive visualizations for both tenants and operators, including room temperatures, setpoints, heating status, and system overview screens.

Asset and device hierarchies

The platform models the building structure using assets (building → floors → apartments→ rooms), allowing Energroup to organize data logically and scale the solution easily to larger portfolios.

Rule engine and automation

ThingsBoard’s rule engine enables automated data processing, condition-based actions, and integration with external systems, forming the basis for advanced regulation and optimization strategies.

Role-based access control

Different user roles ensure that tenants can only access their own apartment data, while operators have full visibility and control over the entire installation.
