kumo cloud‪®‬ 4+

Overall great — definitely read the instructions before figuring out how to fully operate

ETA — most of what I initially said was inconsistent turned out to be user error on my part. (I didn’t understand that you could not use split modes throughout the entire house.) Bear that in mind when using! For example, we live in New England and quite often the temperatures can fluctuate quite a bit within one day, especially during certain seasons. So I’ll save you the trouble from digging through the instructions like I had to — ***You cannot use heat AND cooling at the same time in different zones.*** You’d have to shut off one and turn on the other. Aside from that, the system works great. I even find that the App gets us more accurate output over the remotes. Overall very happy with it. Just takes some getting used to / has a learning curve to operate to its full capabilities.

When the app works, it’s great - but unfortunately I have to say that it is inconsistent at best. The times that the temperatures have either risen or dipped within my children’s rooms where I have wanted to modify the temperature settings in some way, the App seems to be glitchy or unavailable or showing the zones as in “standby” and I’m not able to override it or correct it except to physically go in the room and change it with the physical remote itself. Very frustrating, to say the least.

Getting the most out of Kumo

We have been using the Kumo cloud for 2 years. Initially I was disappointed with the running cost. It appeared I had just traded fuel oil dollars for electric dollars. A few less dollars, but a tough argument to sell to my wife expecting a significant savings. THEN I started playing with the programming. We now run the system twice a day using the program feature. One cycle early before we get up and one cycle late before retiring. During January, these two cycles total 12 hours. I adjust the run time as the weather gets warmer, eventually dropping the evening run and this morning I shut down the morning cycle too. We both can access the Kumo cloud on our phones to turn in on or off when we feel the need. The impact to our electric bill has been amazing, reducing our kilowatts demand by nearly 60%. Admittedly we need to be more proactive with turning it on and off, but the savings are significant.

Connection Issues

I have been using the app for at least three years and it will occasionally lose the wifi connection and indicates one or more zones are offline. I can usually fix this simply by clicking on the zone or resetting the router. It’s not ideal, but fine and not necessarily unexpected with routers. More recently, the app has lost all connectively and gives me a no signal error. It also won’t identify or connect to any of my wireless channels even though previously connected. This is even after resetting the router multiple times and trying to connect to my 2.4 ghz channel and the other channels directly by typing in the network name and password. It just spins and does not connect.

Each of my four zones are connected to Alexa and two continue to work only through Alexa, so something is connected even though the app says otherwise. It’s very frustrating since I like to check and adjust temps in each zone when I’m away.

The system is way to expensive and WiFi connections are way too common to be experiencing problems like this, especially after a few years of use. I’m hesitant to delete the app and start over since it was incredibly hard to connect each unit to the app in the first place and I don’t want to lose the two WiFi connections I still have through Alexa.
