MClimate Enterprise and LoRaWAN Building Devices

MClimate is a company based in Sofia, Bulgaria that develops IoT hardware and software for energy-efficient buildings, built around the LoRaWAN wireless protocol. It addresses the need to monitor and control heating, cooling, air quality and electricity use in existing buildings without rewiring.

The portfolio covers climate and energy control devices (Vicki radiator thermostat, 16A Switch & Power Meter, fan coil thermostat), sensors for CO2, temperature, humidity and occupancy, and water leak control. Devices connect through one LoRaWAN gateway per building to the MClimate Enterprise platform or to any building management system. Case studies include UK retirement homes, Danish schools and a German office.

• 16A Switch & Power Meter: relay with real-time and historical energy metering, schedules and remote switching over LoRaWAN.
• Vicki and thermostats: smart radiator, wireless and fan coil thermostats for room-by-room heating and cooling control.
• Sensor range: CO2, temperature, humidity, light and PIR occupancy sensors, including the PIR mini launched in 2026.
• MClimate Enterprise: platform for monitoring, dashboards, analytics and reports with a customizable end-user app.
• BMS integration: open protocol and gateway exposing data through Modbus, BACnet and KNX.
• Maintenance features: over-the-air firmware updates and AES encrypted communication.

Hotels in Vietnam can meter and switch guest-room loads and monitor CO2 with one gateway per building. Office towers can add occupancy-driven HVAC control to an existing BMS. Schools and hospitals can track air quality and heating by room.

Retrofit-friendly devices that fit behind wall switches and need no rewiring. Open protocol with no vendor lock-in and direct BMS integration. One LoRaWAN gateway per building can serve more than 1000 devices. Real-time and historical power metering on the 16A switch supports room-level energy tracking.

Building owners increasingly retrofit existing stock with low-power wireless sensors to cut energy costs and meet efficiency targets. LoRaWAN suits this because of long range and low maintenance. In Vietnam and Southeast Asia, growing commercial and hotel stock and rising electricity prices raise interest in room-level monitoring.
