MRCOOL SmartHVAC

Today I called the customer support for the Mr. cool iPhone app. And Ian helped me walk through and set up heat and cool comfort modes and schedules to activate the comfort temperature modes. Ian was very attentive, listened very well, and was very clear and his step-by-step instructions. Maybe I could’ve figured it all out myself with a lot of trial and error. But, Ian made it easy to set up a complete summer schedule for me using the comfort modes to automatically turn on and turn off the heating or cooling depending on the room temperature.

Too difficult to set up the app

I’m 74 old and this DIY ESeries mini split is the best purchase I’ve ever made. Easy install, well engineered, and top quality. 😄 happy wife happy life!

terrible app does not work

I bought this unit and it’s not working and there is no support available from Mr Cool. It is terrible

So far have not been impressed by the functioning of the manufacturers app. The app does not appear able to effectively communicate with the unit and does not know if the state of the unit was changed either manually or via the physical remote. Very inefficient way to try and manage a device. Also, some of the core functionality contained in the remote is not contained in the app. This is very odd as to be accessible via the remote means that the base code hooks are available, but apparently just not utilized in the application itself.

The app does work. However, not reliably. All of my issues revolve around schedules. I have found that I must hard reboot about every 2 weeks to reenable scheduling that just stops. The issue is not intermittent WiFi because the schedule does not resume at any point. Behavior is stuck at the last setting before schedules stopped working. As mentioned a hard reset fixes the issue for about 2 weeks. Since I don’t know when this will happen I cannot leave anything really temperature sensitive in the space because the unit may not come on as expected.

I like being able to change the setting remotely for my out building/ office. What I cannot find is what is the setting pos1 pos2 pos3 ?

It doesn’t pull a lot of electricity.

Took forever to connect my mini splits to Wi-Fi. I had to keep restarting and removing and adding the units until finally they would synchronize
