ThermoSense
Wireless Window AC Controller
The ThermoSense Wireless Window AC Controller adds remote control and scheduling to standard window AC units. It mounts externally, runs on 230V AC and links to a MachineSens gateway over NRF 2.4 GHz, up to 100 m away. BuildOT One then lets you monitor each unit, set schedules and limit setpoints from one screen.
A clever start to efficient cooling that helps decrease your energy costs.
MachineSens IoT® ThermoSense NRF Window AC controller is a high-tech intelligent device that offers centralized monitoring and management of heating and cooling system in offices, homes, and apartments. It is designed to work with a wide range of Window AC units.
These IoT-enabled intelligent controllers, compatible with various vendors and designed for most HVAC systems, offer automated and centralized energy management for your property, helping cut energy wasted by units left running.

System Architecture
Our intelligent gateway gathers near real-time data from all wireless Window AC controllers within its range.
It converts the raw data into a user-friendly JSON format and publishes it using the MQTT protocol.
This data can be transmitted to either a local or cloud MQTT broker through Ethernet, LTE (4G), or WIFI.
The individual Window AC units can be centrally controlled from MachineSens IoT Cloud Platform. The MachineSens IoT Cloud Platform enables: –
- Monitoring & Control: Wireless Split & Window AC IoT device enables remote monitoring and control of the AC equipment.
- Data Analysis: IoT devices transmit this data to a cloud based central software system for real-time analysis and notifications.
- Optimal Setpoints: The IoT solution (Hardware + Software) enables automated or centralized control of the AC units temperature to maintain comfort while minimizing energy consumption.
- Reporting: The system can generate energy usage reports (virtual metering), helping users understand their consumption patterns and make informed decisions.
- Programmed Schedules:
- Scheduling – Desired schedules can be programmed in the cloud-based software platform for control & monitoring. The IoT system can respond to demand response signals, reducing energy usage during peak periods. Specific times for system operation, such as when the HVAC should start or stop, temperature setting can be enabled or restricted.
- The AC units set points and operation can be optimized based on weather conditions.
