About this app

MRCOOL SmartHVAC App works with MRCOOL Smart Controllers to convert MRCOOL Air Conditioners & Heat Pumps to smart ones. Our smart controllers work with this App to help you convert your existing or new ACs to smart ACs. You can control your MRCOOL ACs through your smartphone or simple voice commands (our smart controllers are Alexa & Google Home enabled).
These DIY controllers are extremely easy to setup. You can automatically turn the air conditioner or heat pump OFF when you leave the premises and start to cool/heat once you arrive as per your settings. This App gives you complete control of your heating and cooling. It figures out when you're at home and when you're out and adjusts the settings to provide comfort and energy savings.
You can set weekly schedules for your air conditioners, monitor usage history, set air conditioning action in relation to your locations, see the air filter status of your AC and lot more. You can set intelligent temperature based triggers for your air conditioners by using the ‘Comfy’ feature under ‘My Rules’ section of the app. Comfy lets you set triggers to personalize the operation of your AC. It helps you automatically change your AC settings if room temperature goes above or falls below a pre-set value. It helps you reduce your energy bills with lot of convenience.

I find it hilarious they completely forgot (or hid) the ability to delete comfy rules. kinda like they forgot to add the ability to uh... share it with other people? Sharing credentials is such a bad idea. The app is a bit confusing at weird, and doesn't work the way you would expect. For example, I tried to schedule a comfy time to only work at night, but it just doesn't work at all.

I have had the app and unit installed in my home theater for about 4 years. Other than me accidentally removing the unit from my Wi-Fi, it works reliably. I'm unable to teach the IR codes to my Logitech remote. As my environment is completely dark, I need to turn off the LED display on the Mr. Cool unit. My only option is to use the remote. however, I wish I had an option in the app to turn off the LED display. Seems like this option should be in the app. I might be missing it's locations though

this app is horrible. devices randomly go offline. don't waste your time setting a heating or cooling schedule. it will only work for a day until you have to go in manually every time you want to change the temp setting. air filter cleaning reminder notifications don't ever come even if you have them on. app is a great idea. very poorly executed.
