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.

App regularly shows units offline and uncontrollable. Router shows connected fine. Often will not reconnect unless the router or MrCool is shut down at breaker. Still, all units do not always reconnect. And, if you have comfy program on and app disconnects, the remote will not override it, so if you try to turn unit off it will follow comfy and turn back on. Replaced router twice with different brands. tech support did try to help. After 2.5 years, I give up. sorry, gotta go throw the breaker!

there is no way to delete the old Mr Cool "Smart Thermostat" from the app after replacement with a new one. Also, the history will occasionally display incorrect run times by overwriting a weeks worth of data and displaying that the unit ran constantly for 24 hours for each day of the week. clearing cache and data as well as reinstalling the app does not correct the issue. The app also lags behind the actual status and current temperature. Fix and it would be 5 stars.

Worked pretty good for about a week until I had to reboot my router, then would no longer connect. Trying to add a new device gets me nowhere. Edit: customer support informed me that pressing the LED button on the remote 7 times will enter discovery mode, allowing the device to be visible. To change the wifi settings in the app, the data must be off and for mesh routers, the one with the strongest signal must be selected. After following these steps, everything worked as it should.
