Smart Wi-Fi Module
for Air Conditioners
Intelligent Control for Daikin and Mitsubishi Electric Units
Enhance your air conditioning system with our smart Wi-Fi module for seamless wireless control using your smartphone, tablet, or smart home platform. It is fully compatible with Daikin and Mitsubishi Electric air conditioners. Whether you are using Home Assistant or the Tuya Smart app, our module provides fast, reliable, and flexible aircon control both at home and remotely.
By making your air conditioner smart, you can integrate temperature sensors and other smart devices to automate cooling based on real-time conditions. This allows precise climate control, energy savings, and a more comfortable environment without manual adjustments.
These smart modules are also ideal for commercial environments where automated scheduling and remote management improve energy efficiency and reduce costs. They are perfect for offices, retail stores, clinics, classrooms, warehouses, gyms, small server rooms, and other spaces where air conditioners are often left running unnecessarily. With centralized control, sensor-based automation, and scheduling, businesses can ensure cooling is activated only when needed, helping to prevent energy waste and lower electricity bills.

Compatible Air Conditioners
The Smart Wi-Fi module currently works with a wide range of Daikin and Mitsubishi Electric wall-mounted and cassette air conditioners that are equipped with an external control interface on the main board.
MITSUBISHI ELECTRIC
The Wi-Fi module is compatible with most Mitsubishi Electric inverter air conditioners, including both wall-mounted and ducted systems. As a general rule, if your indoor unit includes a CN105 connector, it is supported.
The CN105 port is typically located on the control board of Mitsubishi Electric indoor units and is used to interface with remote controllers or third-party modules. This makes it an ideal point of connection for the smart Wi-Fi controller.
Below is a reference list of commonly supported Mitsubishi Electric models. However, this list is not exhaustive. If your model is not listed, please contact us to confirm compatibility.

DAIKIN
The Wi-Fi module is compatible with a wide range of Daikin air conditioners, including wall-mounted and cassette-type indoor units. If your unit includes the S21 connector (for wall-mounted models) or X50A and X35A connectors (for cassette systems), it is supported by the smart Wi-Fi module.
Some Daikin models may require an additional Daikin interface PCB such as the BRP067A42 or BRP980B42. These are official Daikin accessories designed to enable smart control features and are fully supported by our system. We are able to supply these boards if needed, please contact us for more information.

FAQ
General
These smart Wi-Fi AC adapters and controllers are third-party devices and are not official products from the air conditioner manufacturers. They are designed to work independently, allowing users to control their air conditioners outside the original manufacturer ecosystem.
These modules do not integrate with official manufacturer apps. Instead, they give users the freedom to connect their air conditioners to popular smart home platforms like Home Assistant or Tuya, enabling advanced automation and control.
Yes, you can replace the original OEM Wi-Fi module. Our smart Wi-Fi adapter uses the same connection port as the official OEM adapters for Daikin and Mitsubishi Electric air conditioners, making it a direct replacement. By using our module, you can integrate your AC with Home Assistant or Tuya, unlocking advanced smart home features like real-time climate monitoring, smart thermostats, remote automation, energy-saving control, and more precise temperature management than the standard OEM module allows.
These smart Wi-Fi AC controllers and adapters are compatible only with select brands, including Mitsubishi Electric and Daikin. They are not universal, so make sure to check brand and model compatibility when purchasing a smart controller or Wi-Fi adapter for your air conditioner.
The Wi-Fi module can report power usage and energy consumption if your air conditioner model supports these features. Our smart adapter passes through all available data from the unit, meaning it will report at least the same information as the original manufacturer Wi-Fi adapter.
IR blasters can only send commands and rely on line-of-sight, guessing the AC’s status and needing external power. Our module plugs directly into the AC’s internal port, giving true two-way control, accurate status reporting, 100% reliable command, and a clean, clutter-free install with no extra power required, just like the official adapter but at a much lower cost.
Yes, our smart Wi-Fi modules have been rigorously and comprehensively tested on a variety of Daikin and Mitsubishi Electric air conditioner models. They are fully safe to install and use, ensuring reliable performance on supported units.
No, we do not offer installation services. However, installation is straightforward and we provide clear guides with videos.
