### 1/5 — Took an already bad app and made it worse

*2026-08-24, version 3.5.0*

Awful. Continues to switch from either cooling (in summer mode) to heating, or switches on its own to winter mode.

### 1/5 — Obscure.  Confusing. Poor

*2026-08-22, version 3.5.0*

Why does Mitsubishi make this so stupidly obscure.

### 1/5 — ANNOYING BLUETOOTH PROMPTS

*2026-08-18, version 3.5.0*

Every time I open the app it asks for bluetooth pairing permissions. NO. I already have my system/app/phone sync’d up via WiFi. Now every time I want to change the temp I have to deal with an annoying popup.
Also, the initial pairing process was very finicky and inconvenient.

### 2/5 — Just had a heat pump installed

*2026-08-17, version 3.5.0*

The app interface with the heat pump is not great. I had extraordinarily difficult time in getting the app downloaded and working from my phone. This was most likely a major fault of the installer who didn’t transfer the information from heat pump to me until several day after installation. They were under the impression that the app and its connection to the heat pump does not work seamlessly. 
I recently had switched to a different internet provider and had to call the installer to help me get back online. We had to stand next to the furnace in the basement and hold my phone within 6 inches of the transponder to get connection. I was not impressed. 
Overall, the installer advised me to not use the app but make adjustments at the thermostat.

### 3/5 — Consumer app stripped of many useful features, no way to reset “check filter” reminders

*2026-08-16, version 3.5.0*

App works fine but has been stripped of all useful configuration features (hidden in a contractor app?) which makes the app not as useful as it could be. 

There is no way to get questions answered by the company and seeming no
Way to reset the annoying “check filter” reminder in the app for each of my 7 units despite me cleaning them out myself following YouTube. 

Could be improved

### 1/5 — Setting doesn’t hold

*2026-08-16, version 3.5.0*

Still not holding my settings. 70s today and humid. Tried putting it in “dry” mode at 67 deg. Yes I did confirm. Found it “off” shortly after. Reset and tried again, same result. Switched to “cool” mode set at 67, and now the set mode has reset itself to 78 multiple times.  I love the heat pump, but wish I would have gone with the installers other brand now.

### 1/5 — Doesn’t work

*2026-08-15, version 3.5.0*

Are you ever going to fix this app? It’s actually worse than Kumo Cloud which at least connected to all 4 of my splits. This one only connects to 3 and I have to use the remote for one. On the 3 it does work for it’s unreliable and doesn’t always actually turn the splits on/change the temp when it says it is.

### 4/5 — Easy to use

*2026-08-13, version 3.5.0*

Once you install the mobile app you expand the accessibility of the Mitsubishi Mini Split. I can travel and have peace of mind to adjust temperature as needed for changing seasons. 5 out of 5 stars!

### 1/5 — Not following schedule

*2026-08-13, version 3.5.0*

My AC is not following the schedule I set using this app. It will remain running when it is supposed to turn off. It will turn on randomly. This is very inconvenient.

### 1/5 — Horrible

*2026-08-12, version 3.5.0*

Can’t even log in. App is stuck in a loop and won’t even let me put in the correct email. I have deleted app, rebooted phone,  added app again, updated phone, deleted app cache. It still keeps the wrong email address stored. Spent a lot of money on this system and can’t even use the app.
