Generally I’m pleased with the app as it controls my 2 Mitsubishi units exactly as I have it set. However, since updating to ios 14.1 the app occasionally closes itself shortly after opening and my ‘Scenes’ disappear! After five minutes or so I reopen the app and it’s back to normal. It needs to be updated for the latest iOS

I have been using the app with my two Mitsubishi splits for about 4 years now. The app used to crash and it still crashes. During the hot summer, often the app couldn’t talk to the system presumably because everything goes through some remote server that couldn’t handle the amount of traffic to control hundreds of systems? As others have said, installing the modules into the air handlers basically removes an awful lot of the options you should be able to control with the IR remotes, and a lot of the options that should be available in the app (such as side to side vent control, Eco and Boost modes) just aren’t, and the app has never been improved or updated. Time scheduling does work using ‘scenes’ but could be so much better, and why no integration with Alexa etc? You expect developers to improve features and performance over time, not just sit back and take the money for a product that is clearly not keeping up with technology.

Using this app to control three MHI SRKxxZS units. Setup was a bit fiddly as the instructions were slightly confusing and the WiFi modules were hidden inside the air conditioning units so couldn’t see the status LEDs. Once I understood the concept of connecting the modules to WiFi and then adding them as controllable devices to the app, they seemed stable and worked well. There are a few downsides though. The app crashes a lot, there are a few useful functions missing (like ‘timers’ and setting the fan speed to ‘auto’, for example) but most disappointing is that there is no integration with Alexa, Google or HomeKit. That would definitely make it a five star product in my view if they could sort that out. Overall, it’s a good app but has potential to be much better.

I think for me, while having this is super useful when I want to manually do something, and great for setting up scenes (although a bit clunky), the fact I can’t ask Alexa or Siri or Google to also do this is a shame.iOS 18 added a whole bunch of new amazing stuff around App Intents so that ‘new’ Siri can better interact with the apps on devices. I’d suggest looking into this so it helps open up a world of home automation possibilities.
