BEPOSITIVE 2025 in Lyon, where wherever SIM was an exhibitor this year at the end of March, clearly demonstrated this: The demand for reliable, wireless IoT connectivity in the energy and building sector is growing rapidly. Whether for operators of photovoltaic systems, in the HVAC sector or in the context of building automation, connectivity is becoming a key factor for successful digitalization.
Decentralized systems that are difficult to access in particular need a secure and scalable connection. And without complex and cost-intensive cabling. This is exactly where M2M and IoT SIM cards come in: They connect machines, sensors and systems via mobile communications - worldwide, fail-safe, controllable at any time and, above all, wireless.
Application examples: M2M SIM cards provide the right connection here
Power generation & grid integration
- Ground-mounted PV systems: Photovoltaic systems in rural areas are often difficult to reach. This makes a stable connection for monitoring, fault diagnosis and grid integration all the more important. M2M SIM cards enable remote access to inverters, data loggers and sensors without local infrastructure and expensive cabling.
- Transformer stations & energy distribution: Secure energy distribution includes numerous networked operating resources: transformer stations, grid changeover switches, storage solutions. These units can be monitored securely, redundantly and independently of the grid via M2M SIMs - even at remote locations.
Intelligent buildings & technology
- HVAC & building automation: Heating, ventilation and air conditioning technology (HVAC) and smart building solutions need reliable connectivity - especially for complex systems with many decentralized components. With IoT SIMs, these devices can be connected easily and securely, even in existing buildings or temporary installations.
- Typical applications:
- Control & regulation of HVAC components
- Energy consumption monitoring
- Integration into central building management system
- Facility management: Large property portfolios present facility teams with the challenge of monitoring plant technology centrally across locations. M2M SIM cards offer an IT-independent solution for reliably connecting sensors, maintenance units or alarm systems.
- Typical applications:
- Condition monitoring & limit value messages
- Remote diagnostics & maintenance planning
- Retrofitting existing buildings
Temporary & mobile applications
- Smart Construction: Construction sites are digital black boxes - if there is no connectivity. M2M SIMscreate temporary, ready-to-use data connections for construction containers, mobile energy supply, sensors or monitoring systems - project-based and flexibly scalable.
- Typical applications:
- Construction site monitoring & access control
- Energy consumption measurement on site
- Device tracking & logistics
