Milesight WT101 Smart Radiator Thermostat

The Milesight WT101 is a smart LoRaWAN® radiator thermostat designed to help businesses, landlords, public sector organisations, and facilities management teams improve heating control across radiator-based buildings.

Traditional radiator valves can lead to overheating, temperature swings, unnecessary energy use, and limited visibility for facilities teams. The Milesight WT101 helps address this by using real-time temperature monitoring and automatic valve adjustment to regulate the amount of hot water entering the radiator. Milesight describes the WT10x range as delivering dynamic precision by monitoring room temperature and automatically adjusting valve opening for consistent comfort and improved energy efficiency.

For smart buildings and facilities management projects in Ireland, the WT101 is well suited to offices, apartments, commercial buildings, schools, public buildings, healthcare facilities, managed accommodation, and multi-room premises where heating control needs to be improved without major rewiring.

The WT101 uses LoRaWAN® wireless communication, making it suitable for large buildings, multi-site deployments, and retrofit projects where Wi-Fi coverage or additional cabling may not be practical. It can be deployed with Milesight LoRaWAN gateways and a Milesight cloud platform to provide remote monitoring, scheduling, and smart heating control.

Milesight lists key WT101 features including automatic temperature control, valve opening control, heat plans, freeze protection, open-window detection, tamper alarm, effective stroke, child lock, external sensor mode, FUOTA, and NFC configuration via mobile app or downlink.

The WT101 supports M30 × 1.5 mm default valve fitting, with optional adapters for RA, RAV, RAVL, Giacomini, and M28 valves, helping support a wide range of radiator installations. It is powered by 2 × 1.5V Li-FeS2 AA replaceable batteries, with Milesight listing battery life of around 8 years at SF7 EU868 or around 5 years at SF10 EU868 under stated laboratory test conditions.

TITAN can supply the Milesight WT101 Smart Radiator Thermostat nationwide across Ireland as a thermostat-only product or as part of a complete Milesight LoRaWAN smart heating solution, including gateway selection, configuration, cloud dashboard setup, and deployment support.

Irish Use Cases

Facilities Management

The WT101 gives facilities management teams greater control over radiator-based heating across buildings and rooms. It can help reduce overheating, improve comfort, and make heating control easier across offices, public buildings, managed properties, and multi-site facilities.

Smart Buildings

For smart building projects, the WT101 can be deployed as part of a wider Milesight LoRaWAN ecosystem alongside gateways, environmental sensors, IAQ sensors, magnetic contact sensors, and cloud dashboards.

Offices & Commercial Buildings

The WT101 is useful for commercial buildings where individual rooms, meeting rooms, shared spaces, or zones need better heating control without major changes to existing radiator infrastructure.

Apartments & Managed Accommodation

For apartments, student accommodation, serviced accommodation, and managed housing, the WT101 can support room-level heating control, scheduling, and better energy management.

Schools, Public Buildings & Healthcare Facilities

The WT101 can help public sector and healthcare buildings improve room comfort and reduce unnecessary heating by giving teams better control over radiator valves and schedules.

Retrofit Heating Control

Because the WT101 uses LoRaWAN® and battery power, it is suitable for retrofit projects where installing new wiring would be costly, disruptive, or impractical.
