What's New

Version 2.6.1

This version supports integration with kumo station™ (PAC-WHS01HC-E), a new product that enables centralized control of your Mitsubishi Electric HVAC equipment along with accessories such as third-party backup heaters, humidifiers, dehumidifiers and ventilators.

Further, kumo cloud now supports the Wireless Temperature and Humidity Sensor (PAC-USWHS003-TH-1), an optional part to provide remote sensing capabilities to the Wireless Interface.

System changeover is now supported to allow Wireless Interfaces attached to indoor units in some model families to negotiate the system transition from heating to cooling and back automatically.

This version of kumo cloud also includes many user interface improvements, particularly on tablets, as well as bug fixes and other feature improvements.

Necessary but seriously underdeveloped

If you have never seen or heard of Ecobee or Nest, you may innocently think that Kumo Cloud is pretty good. It is effective enough and virtually necessary to control multiple indoor units (I have 5) from one location, but it is the saddest excuse for a smart HVAC control app. It's never updated, it doesn't support 75% of the functionality that the indoor units are capable of (which you can control via individual remotes), it's not particularly user friendly, it lacks essential features like vacation mode, and even basic app stability isn't there - I've had many issues with it in the past not saving settings, not making changes I set, etc. (It used to lack all smart home integration support - another hugely disappointing thing, but luckily they quietly added Google Home support - that's a start at least but they still have a long way to go.) That said, I'm a big fan of my Mitsubishi heat pump system and it's super sad that their smart home control system is so anemic and underdeveloped. I really really want to be able to recommend Kumo Cloud for more reasons than the simple fact that it's pretty much only reasonable way to control multiple units in one place but I will continue waiting and hoping and praying that that Mitsubishi can step up their game.


Needs Update

I think this is very convenient when it works however, that’s the biggest issue, it rarely fully works. I have a 7 zone system with Kumo Cloud and Google Home integration. Almost every time I go into the app, at least one unit isn’t available to adjust and next time it’s a different one. If my phone ever locks, I need to manually kill and relaunch the app. The programming is nice, but I really bought the app to not need the remotes. It’s super frustrating that I cannot change the I-See sensor settings, away detection or throw direction from the app. Why do I need 7 different remotes in 2018? The same issue with the app seems to exist with the Google Home integration where it’ll occasionally respond with “Cannot Connect to Kumo Cloud unit right now”, and while having it give me the set and current temps is nice, it seems more complicated than it should go change the set temp. I’ve tried a few ways and it’ll often say “that’s outside of the available temperatures”. Not what I expected for how much I paid for this “state of the are equipment”


Still needs work, but it works so far.

This is a must have for Mitsubishi split units as the stock remotes are junk. However the Kumo developers need to make the touch interface better. I have to press the temp up and down multiple times for it to register. Also maybe add room temp and ac temp in the little room squares/ tiles on the home page. Another thing is maybe include a update/ refresh button as trying to get the ac units to show up on the app rarely works and you have to manually enter the id number and MAC address for them to work. So far the app works across multiple iPhones so I guess they fixed that issue. All in all keep at it Kumo developers, it's improving but it could be better! 3.5-4 stars so far.

Update: Ver 2.6.1 is very buggy with newest iPhone iOS 11.3.1. Sometimes exiting and re entering the app freezes and does not register screen touch. Please fix!
