Mitsubishi Heavy Industries (MHI) makes residential and commercial air conditioners and heat pumps through its Thermal Systems business, which is separate from Mitsubishi Electric. Split systems such as the SRK/SRC range are controlled with a Wi-Fi interface and a phone app, and larger systems can be tied into building controls through KNX and Modbus gateways.
Where Mitsubishi Heavy Industries fits in a smart home
MHI air conditioners connect over 2.4 GHz Wi-Fi, either through a built-in module on recent models or a plug-in wireless LAN interface. Two app families exist: MHI's own Smart M-Air for the WF-RAC style modules, and the Intesis (HMS) AC Cloud Control gateway, which adds Alexa, Google Assistant, Siri Shortcuts and IFTTT through the cloud. Which one applies depends on the adapter fitted, and the two are not interchangeable.
That suits remote control of a split system and voice control where an AC Cloud Control adapter is installed. It is weaker for a tidy smart home setup: no Matter support was found, Home Assistant and Homey support comes from community projects, and some adapters are cloud-only with no local interface. Larger buildings are better served by the KNX and Modbus gateways.

MHI's own app for built-in or plug-in Wi-Fi modules. Basic controls, favourite settings, power consumption display, vacant property mode and weekly timer notifications. The App Store listing requires a connectable air conditioner and a wireless LAN interface bought separately and names no specific models. Published by Mitsubishi Heavy Industries Thermal Systems.
Cloud app from HMS Industrial Networks for AC Cloud Control gateways, which MHI's Australian arm calls Wi-Fi Control. On, off, mode, fan speed, vane position, temperature, alerts and multiple users. The App Store listing does not name voice assistants or brands, and points to a compatibility list on the developer's website.
For package air conditioners. Connects by Bluetooth to a separately sold RC-ES1 series wired remote, one phone at a time, for remote operation, status and error monitoring and simplified remote setup. Published by Mitsubishi Heavy Industries Thermal Systems. No Wi-Fi or cloud role is described.
HMS app for Airconwithme modules fitted to Mitsubishi air conditioners. Controls on or off, mode, set point, fan speed and vane position, with scenes and timers. A user-written review mentions an MHI SRK unit, and the listing names no supported models. Reviews say it has no Alexa, Google or HomeKit integration.
Spanish-language iPhone app for the SMART range, which needs the WIFI SMART MHI adapter. The seller is an individual, with a Lumelco copyright notice, and the listing calls Lumelco the official distributor for MHI Air-Conditioning Europe. Mode, temperature and fan speed only.

Connection
Wi-Fi
Yes
Wi-Fi is the main smart connection. The Smart M-Air guide says the product supports the 2.4 GHz band only, with setup through WPS or an access-point mode started from the wireless remote's menu. The HMS interface for MHI units is listed as 802.11 b/g/n on 2.4 GHz. MHI Europe says built-in Wi-Fi exists on the ZSX, ZR, ZS and ZTL residential ranges. We could not confirm the SC-WIFI-K model number on a fetched page.
M-air Pro talks to RC-ES1 series wired remotes over Bluetooth, one phone at a time. The AC Cloud Control gateway for domestic systems is configured over Bluetooth, but its normal control path is the cloud over Wi-Fi.

HMS (Intesis) makes gateways for MHI systems. An Intesis Modbus RTU interface covers MHI FD and VRF systems, one indoor unit per interface, and an Intesis KNX gateway for MHI air conditioning connects through KNX TP-1 and the Superlink A-B terminals. These are HMS products for MHI, and we could not confirm that MHI itself lists them.
MHI Air-Conditioning Australia says its Wi-Fi Control works with Amazon smart home devices, and HMS lists Alexa for AC Cloud Control. This applies to AC Cloud Control adapters. An HMS representative called Alexa documentation for Airconwithme limited, and Smart M-Air listings mention no voice support.
The same MHI Australia page lists Google Assistant and Google Home alongside its Wi-Fi Control app, and HMS lists Google Assistant for AC Cloud Control. No Google Home page for Smart M-Air was found.
MHI Australia mentions Siri voice control and HMS lists Siri Shortcuts, but neither page describes a HomeKit or Apple Home listing. Reviews of the Airconwithme app say it cannot be controlled through Siri.
No built-in integration found, though Home Assistant's own integrations page could not be opened. A community integration for WF-RAC modules talks to the module's local HTTP API without the cloud, polling every 60 seconds. Its page says it is in the HACS default list and needs a recent Home Assistant, while an ASUS guide installs it as a custom repository. The module accepts one client at a time, so the Smart M-Air app and Home Assistant can collide. It does not cover Mitsubishi Electric units. Other community projects use IR or an add-on module.
Community apps by independent developers, not Athom. A WF-RAC app by Edwin van de Pol works with WF-RAC modules through Smart M-Air and is not compatible with INWFIMHI001I000 adapters configured through AC Cloud. Its Homey store page lists Homey Cloud, Homey Pro and Self-Hosted Server and says Homey Bridge is required, while the forum thread only tags Homey Pro, so which applies is unresolved. A separate Intesis app covers WMP units locally and not AC Cloud units.
No dedicated node found. The same module says any system that supports MQTT or HTTP GET can use it, which would include Node-RED, but we could not confirm that.
HMS offers a professional REST API for connecting third-party systems to AC Cloud Control. A Homey developer said Intesis declined to share the AC Cloud API for his app, so it is not open to hobby use.
