MRCOOL SmartHVAC 4+

Very Happy

I was using a portable ac in my 12x20 building before and is was a nightmare, constantly missing with temperature fluctuations and noise!
I trashed the Mr Cool DIY systems for almost a year before I bought one. It came in and I installed it in about 4-hrs, very straightforward and very easy. When I first powered it on to ac and went inside to check it I thought oh crap what did I do wrong it’s not working, but it was working fine, it is so quite I thought it was off, both the inside unit and the outside unit are extremely quiet, now it’s winter at 29 degrees and my room it tuning at 77 like a champ, I cannot express how satisfied I am with this product!
Have recommended it to several other for there use
Thanks Jerry

It works, but needs a major overhaul

Does the app work with the unit? Yes, it does work. However, setting up the unit is a bit odd. You have to plug a USB dongle into the mini split. This looks like they made Internet connectivity an afterthought. Next, connecting the unit is not quite as simple as what they make it out to be. Then there’s also the confusion between the remote control that comes with the unit, the wall temperature gage, and the main mini split. Each of the three give you a different temperature reading even though they’re in the same room at the same height level. Lastly, the app is greatly lacking compared to competitors. If you look at something like a nest, the unit is well-made, and so is the app. It works near flawlessly, and is intelligent to understand your habits and needs. Setting up a Nest is very simple, managing it remotely is just as easy. The app is well designed. Mr. Cole needs to purchase a nest begin to use it, and then implement similar changes. Most notably, they need to have an easier automated schedule. They also need to find a way to have the unit turn off when it reaches the temperature requested by the user. Instead, the unit remains on chewing up valuable electricity. I can’t say that I’m disappointed with my mini split because it does work. However when you compare it to other units on the market they have blown Mr. cool out of the water. They definitely need to catch up especially with their hardware and software capabilities.

Humidity not reporting in app

I have tried this app on my DIY-18-HP-230 3rd gen unit with both the MrCool mini-stat that came with the mini-split and I bought the WiFi version - Smart HVAC Ductless Mini-Stat separately and those units show temp and humidity on them. They do not transfer the humidity to the app OR they do and the app won't show it. I have gone through all the settings and I can't make it work. The app screenshots show humidity, the mini-stay documentation shows humidity working in the app - how do I see the data? I need to monitor the humidity of a remote building.

UPDATE: They responded and asked me to submit a support case. I don't appreciate how places like to use this strategy because it can easily make their customers seem unreasonable. However, I wrote this review AFTER I sent in a support case directly from their website and never heard back (I've checked my spam folder). It would be nice if they could just respond here. I've tried all the typical stuff like uninstall and clean reinstall, etc. but my feeling is this feature doesn't exist. If not, just say so. If I was supposed to buy another piece of equipment just say so. I can't be the first person that experienced this basic problem.
