One of the reasons that I chose this AC at the time was that supposedly it could be controlled via Wi-Fi. I have an excellent home network, with a consistently strong signal. The top of the line router is in a prime location within the same room as the AC. I do not have a single issue controlling various Wi-Fi enabled devices on my network. After spending hours trying to get this thing to work with the app, I just gave up, and I never give up when it comes to getting a device to connect. If you see a similar AC (10k BTU), without Wi-Fi capability, save some money and get that instead. BTW, it does a decent job of cooling a large room and setting it up in a NYC apartment window was a breeze.
