Mitsubishi Electric is a Japanese electrical and electronics group whose residential climate range covers split and multi-split air conditioners, ducted systems and air-to-water heat pumps. Smart control depends on the region: Europe and other markets use the MELCloud and MELCloud Home apps with a Wi-Fi interface, while the United States uses the Comfort app, formerly kumo cloud.
Mitsubishi Electric connects units through a small Wi-Fi interface plugged into the indoor unit (or built-in Wi-Fi on some models) and a vendor cloud. MELCloud Home states that its Wi-Fi adapters work only on 2.4 GHz and that third-party Wi-Fi interfaces are not supported. We found no Matter, Thread or Zigbee support and no hub to buy.
That suits people who want remote control, schedules and energy monitoring for a heat pump from one app, and who are happy to rely on the vendor cloud. It is weaker for local-only automation: MELCloud Home's FAQ says Wi-Fi devices need an internet connection, and Apple Home and SmartThings support was not found. Home Assistant is the strongest open option, with built-in integrations for MELCloud, MELCloud Home and the US Comfort system.

The current app for Europe and other MELCloud markets, described as built from scratch to replace the earlier MELCloud app. It offers live control, weekly schedules, energy monitoring, scenes, guest access and multiple properties, plus a browser version at melcloudhome.com. It needs an MAC-567IF-E or newer Wi-Fi adapter, or the CL-HA1-A1 cellular adapter. Published by Mitsubishi Electric Europe B.V.
The earlier European app, still listed on the App Store and Google Play. Its App Store page lists the PAC-WF010-E, MAC-557IF-E, MAC-567IF-E, MAC-577IF-E and MAC-587IF-E interfaces. It does not say it is being retired, and ratings are low (about 1.9 out of 5 on the App Store).
The US app from Mitsubishi Electric US, described as the successor to kumo cloud and released in December 2025. It covers schedules, zones, kumo station management and contractor features, and the App Store listing mentions an Alexa integration flow. It uses the same App Store entry that kumo cloud used.
A US iPhone app kept only for the older PAC-WHS01WF-E adapters, which the developer says do not work with the Comfort app. The listing says the kumo cloud app will be decommissioned soon.
The Australian app for the MAC-588IF-E Wi-Fi adapter and units with built-in Wi-Fi. Mitsubishi Electric Australia lists Alexa and Google Assistant voice control for it. The Australian page does not mention MELCloud.

Connection
Wi-Fi
Yes
Control runs over a Wi-Fi interface and Mitsubishi's cloud. MELCloud Home states the adapter supports only the 2.4 GHz band, that third-party Wi-Fi interfaces are not supported, and that an internet connection is required. A cellular adapter (CL-HA1-A1) exists for sites without Wi-Fi.
Mitsubishi Electric's MELCloud Home page says the platform now supports Bluetooth-enabled interfaces and cellular-connected modules. We did not find which products use Bluetooth.

US local network control
Not mentioned
The Home Assistant Mitsubishi Comfort integration talks to each indoor unit over the local network and uses the Kumo Cloud account only for setup and credentials. Mitsubishi does not document this itself on the pages we opened.
Documented for several regions. MELCloud Home can trigger predefined programs by voice, such as an away program, and the Danish MELCloud Home page describes Alexa through custom scenes. The US kumo cloud skill (November 2018) covers on and off, setpoints, modes and zone status, and Mitsubishi Electric Australia lists Alexa for its Wi-Fi Control App. Which units and regions work with which app varies.
Mitsubishi Electric Australia lists Google Assistant for its Wi-Fi Control App, and the MELCloud App Store version history mentions Google Home and Google voice assistant support added in 2020 and 2021. We found no Google Assistant mention for MELCloud Home or the US Comfort app, so support depends on region and app.
Three built-in integrations exist, maintained by the Home Assistant project rather than Mitsubishi Electric. MELCloud (cloud polling) covers air-to-air and air-to-water heat pumps. MELCloud Home (cloud push, added in Home Assistant 2026.7) covers units on a MELCloud Home account. Mitsubishi Comfort (local polling, added in 2026.6) covers US indoor units set up through Kumo Cloud. The community hass-kumo component also exists, and its page says Mitsubishi's changes affected credential retrieval for the US.
A community app by Olivier Zalmanski, not Athom, which states it is not endorsed by Mitsubishi Electric. It covers MELCloud (air-to-air, air-to-water, ventilation) and MELCloud Home (air-to-air, air-to-water). The store page lists Homey Cloud, Homey Pro, Homey Pro mini and Self-Hosted Server, and does not mention a Homey Bridge.
The MELCloud Binding is in openHAB's add-on list, maintained by the openHAB project. It covers air conditioners and heat pumps through a MELCloud account, with a minimum polling interval of 180 seconds because of Mitsubishi's API limits. The binding page does not mention MELCloud Home. Community forum threads about a MELCloud Home binding appeared in search results, but were not opened.

Official developer API
Not found
No public developer API was found. The Danish MELCloud Home page does not mention an API, and the MELCloud Home FAQ does not mention open access or local control. The Home Assistant and openHAB integrations use the cloud service or, for US units, credentials retrieved from it.
