CN105 smart control options
A Tuya CN105 WiFi adapter for Mitsubishi Electric air conditioning
Choose AcmeLink ME when your project needs Tuya Smart / Smart Life control on a confirmed compatible Mitsubishi Electric indoor unit. Use supported Tuya devices and scene functions to plan smart-home automation; availability depends on the devices, gateway and selected configuration.
WiFi, Zigbee or Modbus: choose the control route
The WiFi version uses a 2.4 GHz network. The separate Zigbee version uses a matched Tuya Zigbee gateway. For a BMS or custom host project, choose Modbus, WiFi + Modbus or Zigbee + Modbus and request the register map and serial settings. WiFi alone does not provide a Modbus BMS interface.
For a Mitsubishi split AC WiFi module or VRF WiFi controller project, confirm the complete indoor-unit model and CN105 interface against the tested list below. The product category or connector name alone does not establish compatibility.
Considering an alternative to a Mitsubishi Electric WiFi interface?
| Original interface reference | Manufacturer documentation | Before choosing AcmeLink ME |
|---|---|---|
| MAC-567IF-E | MELCloud setup documentation | Check the full interface suffix and indoor-unit model. |
| MAC-587IF-E | MELCloud WiFi interface | Compare the required app functions with the Tuya configuration. |
| MAC-597IF-E | MELCloud Home WiFi interface | Confirm whether the project requires MELCloud Home or a Tuya-based alternative. |
| MAC-577IF-E | Manufacturer model documentation | Provide a label photo: MAC-577IF-E and MAC-577IF2-E are distinct references. |
The references above help identify your existing installation. Manufacturer compatibility lists apply to the original interfaces; they are not the AcmeLink ME tested model list. Check the ME tested models below and send your exact indoor-unit model for confirmation.
If your project specifies MAC-567IF-E, MAC-587IF-E, MAC-597IF-E or MAC-577IF-E, send that reference together with the indoor-unit nameplate and required control functions. These are Mitsubishi Electric model references, not AcmeLink ME model numbers or a verified one-for-one replacement list.
AcmeLink ME provides a Tuya-based control route. Do not assume operation with MELCloud, MELCloud Home or every feature of the original interface. Confirm the exact unit, wiring, retained controller and required app/BMS functions before approving a sample. Project pricing depends on configuration and quantity.
Manufacturer references: Mitsubishi Electric MELCloud WiFi interfaces. AcmeLink ME is an ACMELEC aftermarket product; it is not a Mitsubishi Electric-branded interface.
Before choosing a sample, read the Tuya alternative selection guide and CN105 Modbus and BMS integration checklist.
Choose an ME configuration
Available ME configurations are WiFi, Zigbee, Modbus, WiFi + Modbus and Zigbee + Modbus. WiFi + Zigbee and WiFi + Zigbee + Modbus are not supported.
| Configuration | Control route to prepare | Additional RS485 wiring |
|---|---|---|
| WiFi | 2.4 GHz WiFi; Tuya Smart / Smart Life | None |
| Zigbee | Tuya Zigbee; confirm the gateway and pairing arrangement | None |
| Modbus | RS485 host or BMS; request the matching register map | A/B |
| WiFi + Modbus | 2.4 GHz WiFi; Tuya Smart / Smart Life | A/B |
| Zigbee + Modbus | Tuya Zigbee; confirm the gateway and pairing arrangement | A/B |
WiFi and Zigbee versions use the same wiring but different Tuya modules. Modbus configurations add two RS485 communication wires, A and B, to the indoor-unit connection. Specify the required configuration before ordering; these options do not mean one supplied unit includes every protocol or can switch between WiFi and Zigbee through a software setting.
For Modbus integration, request the register map and serial communication settings for the ordered configuration. Confirm compatibility with the intended controller or BMS. For a Zigbee order, confirm the required Tuya gateway and pairing arrangement before installation.
Enquire about a configuration: WiFi · Zigbee · Modbus · WiFi + Modbus · Zigbee + Modbus. Your selection will be carried into the enquiry form, where you can change it or ask for advice.

How to check your Mitsubishi Electric CN105 connection
Need a wall-mounted screen for room control? Compare the AE-5507 Mitsubishi Electric thermostat route with the AcmeLink ME gateway. The two product routes require their own model and wiring confirmation.
AcmeLink ME connects to CN105 on a confirmed Mitsubishi Electric indoor unit. The connection carries power and communication. CN105 identifies the connection point; it does not specify whether your ME order uses WiFi, Zigbee or Modbus.
- Read the full indoor-unit nameplate. Match the model and suffix against the tested model table. Record the indoor-unit model rather than relying on the outdoor-unit model or the system's sales name.
- Show the board label and connector together. Have qualified HVAC personnel isolate power before accessing the board. Supply a clear photo showing the CN105 marking, connector and surrounding board area; connector location and board layout vary by model.
- Record anything already connected. Include the original controller model and any existing adapter or cable at CN105. Ask for the confirmed connection arrangement before replacing an adapter or planning to share a connection.
- Specify the control route. Select one of the five ME configurations and identify the Tuya gateway or RS485 host where applicable. For an unlisted model or uncertain suffix, send the nameplate and connector photos for review.
AcmeLink ME is the Mitsubishi Electric model. For Daikin P1/P2 installations, review AcmeLink DK. For a project needing centralized control of multiple indoor units, compare the B19 and B27 gateway architectures before choosing hardware.

AcmeLink ME questions
Does a CN105 connector guarantee AcmeLink ME compatibility?
No. ACMELEC has completed testing for the PEFY, PEY and SEZ models and suffixes listed on the ME product page across WiFi, Zigbee, Modbus, WiFi + Modbus and Zigbee + Modbus. Match the full model and connector; other models need a compatibility review.
Does the Zigbee version need a gateway?
Use the appropriate Tuya Zigbee gateway and add the ME module as a sub-device. Confirm the gateway model before ordering. WiFi credentials in the illustrated Zigbee instructions configure the WiFi-connected gateway, not the ME Zigbee module.
Can I order Modbus without WiFi or Zigbee?
Yes. A Modbus-only configuration is available, as are WiFi + Modbus and Zigbee + Modbus. Request the matching RS485 A/B wiring, register map and serial settings for your host controller or BMS.
Where are the WiFi and Zigbee pairing instructions?
Use the revised ME manual and the step-by-step Tuya guide. Pairing mode is indicated by a flashing green light. For Zigbee, add the module as a sub-device through the appropriate gateway.
Can the original wired controller remain connected?
The ME product materials describe retaining the original controller on compatible installations. Send the existing controller model and connection details, including anything already occupying CN105, so ACMELEC can confirm the arrangement before ordering.
