Mitsubishi Electric PAC-USWHS002-WF-2, Wireless (Wi-Fi) Interface Control 2

I sincerely hope this review helps others. I almost gave up on these units and am very glad I didn't. First, customer support from Mitsubishi, while easy to contact, but was highly inaccurate in my experience, until I got the right person, 4 calls, 2 days, several hours, worth it in the end.Here was my problem and my solution.I had a dual band goggle mesh network. My network SSID was named David's Wireless and was a dedicated 2.4 band with 39 devices on it. During install, I kept receiving an SSID error code. I called mitsubishi. My call was answered rapidly, I was connected with a rep who was assertive in her explanation, mesh networks don't work with the unit, she said. Off I went to Best buy to buy a 2.4 only noon-mesh router, $350, easy install, back to unit, same error code, same wireless network name, David's wireless. UGH! Call Mitsubishi again. New rep tells me device has been used prior and needed to be re-set (device reset involves using a paperclip to hold down top bottom on left, a hole, below and to the side of the green light and blinking blue lights.) I was given a case # and asked to wait for level 2 assistance. It never came-hour waiting on phone then dial tone. UGH. Wait a day, too frustrated. Next day new call new rep. They instruct me to make a guest network. They tell me do not use an apostrophe in my network name. It works, but now many of my cameras and other devices are not liking the new router now that it is not broadcasting using a mesh. I think for a moment and decide to try the same solution with my old router. It works! I return $350 router to best buy. I make a new guest network on my google mesh wifi and use it only for the units and the Kumo Cloud. I don't use an apostrphe, it all works. When you are not connected to the wifi band the device is using, as in out of your home, it does take longer for the unit to respond. These are signals bouncing back and forth between servers and is not a very rapid transmission. I am very surprised that I was told mesh networks do not work. They do! I am surprised so many are saying it doesn't work with dual band. It does! It doesn't work with 5g. Dual bands have 2.4 so it may need to be enabled or disable 5g but it does work.The problem was an apostrophe for me in David's wireless.If i didn't have 40 devices connected I could have simply removed the apostrophe and connected device. It also becomes possible that for some routers guest networks will be limited and may not receive data. Solution will be to change setting in guest network or use non-guest network. This device works fine and is great. It is not as easy to install as you'd think but only because of network issues, not hardware or mechanical.{Two blinking blue lights equals no internet signal. Four rapid blue blinking lights means ready for install, and 3 bliking blue means operational and connected to wifi.}

Great Item!! I highly recommend this product! Very prompt delivery. Excellent Seller!

Nice unit once I got through 2 hours of tech support. As of 12/29/24 only old iPhones can be used for set up. I also had to setup a guest 2.4 mhz network on my mesh. Not a huge deal. It will work with new iPhones after it’s setup.

Difficult to setup. Kumo app is terrible and feels like it's from 2011. You cannot setup this device with newer iPhones or Androids.

The entire kumo cloud eco system is poorly thought out and very slow, but that's only the software side of things.If you happen to be unlucky enough to own one of these, it will cause you endless frustration with the adapter's inability to maintain a stable connection. Before you chalk it up to me having a poor signal or a bad network in general, consider the fact that this is about 10 feet away from the prosumer access point that it is connected to and none of the other countless smart devices have trouble maintaining their connection. Yes, even the Lifx smart bulbs that are notoriously bad at maintaining connections function flawlessly on my network.The kumo cloud software that this allows you to use is hot garbage. You get to open the app, then wait 5-10 seconds to see if you are going to be able to control your smart device, then finally change the settings and hope that your changea are actually enacted. This is somewhat mitigated if you use something other than the kumo cloud app like Google Home. Yes, sometimes Google home is able to communicate with your device even when kumo cloud swears that there is no connection after several reloads. But only sometimes, oh and the Google home app doesn't always show all of your device's functionality so if you have a heat pump mini split good luck selecting a mode other than "Heat" or "Off". Note that this used to work fine, but a few months ago the other options disappeared never to be seen again.The only semi-reliable way to use this is to set a static IP or have a DHCP reservation on your network and use home assistant to control it with the kumo cloud extension. When the device has managed to maintain a connection it is much more reliable and instant than the official ways to control it, likely because it uses a local API instead of trying to needlessly route everything through the cloud.I write this as I am currently in my attic about to put my fist through the ceiling below me in frustration as the adapter is now refusing to connect to my wifi again, and can't even be bothered to display status lights until I unplug it a few times and plug it back in. Don't buy this. I wish I hadn't.
