I downloaded this app to use with an Ecodan ASHP. I am amazed that a company as big and well known as Mitsubishi would release such an appallingly useless app!

Mitsubishi please do something about this app. It seems to use a cloud based API rather than a local one. Hence its slow and buggy to use. The app seems to have less functionality than the remote that comes with unit. It’s incredibly frustrating to setup units with the app. In this day an age it’s simply unacceptable.

All the features I needed and was happy. Then internet was out for an hour, and after coming back on the units are now no longer connected to the app. Followed the troubleshooting steps without success. App offers no further help 🤷‍♂️

The app has not been able to communicate with the server since 18/4/2024 meaning I cannot remotely control the heat pump for 4 days now. For someone who relies on remote operation of their heat pump, this is appalling for a respected organisation like Misubish. Please fix the problem in a timely manner and keep your customers informed about any progress.

I have 500mbps fibre internet but this useless app won’t link my air conditioner to my router that are 15ft apart. Terrible

Trying to register new equipment which ought to be straightforward is a nightmare. Constancy error messages with no clue as to what, why or how to fix. Support that just takes you to a map with no explanation as to why. And still no success. Seriously, how hard can it be to have an app that works?

App design is ok. Initial setup is a bit slow and managing routines/timers isn’t that great. Works most of the time, but have to regularly (once-twice a month) remove and re-install it as it fails to send commands to the AC units. Voice commands through google home are also poor, though that may not be their fault.

Customer service is not good , problems with there system but want to charge you to come and fix a brand new installation People have had Toshiba heat pumps and far better service !!!! UPDATE Response from Mitsubishi about this review says it all !!!!

Given the size of Mitsubishi and the high cost of the air con units the app is almost unforgivably bad. Unintuitive and complex to set up. Constantly - and I mean CONSTANTLY - forgets or overrides the basic temperature and vane direction settings. Just randomly assigns values. The app has preset slots but I have zero idea how you are meant to set them up. Overall feels like a shrunken, buggy kiosk app from the late 90s.

The heat pump is fine, this app is not. Therefore, a good heat pump is ruined by a frankly terrible interface from 2004.
