Daikin Comfort Control 4+

I am currently abroad and trying to control my units from the other side of the world. The Daikin units itself were expensive and so were the WiFi units. Today when I woke up the whole house was set to wrong temperatures even though I have deleted all scheduling in their terrible app days earlier. I have a smart home with 150 things, everything works great except the terrible Daikin app. The app has 1.4 in reviews on the App Store. Is it that much to ask for that it does simple things of setting the right temp at the right time as it was advertised to do? You remove a schedule in their app, and it confirms you do so but still it’s there, lingering and invisible to the user. A quick search and I find thousands of other users with the exact same problem our installer said he stopped working with Daikin since their units and support is useless. If they cared they would have spent a minute on fixing the bugs. DKN cloud is also extremely problematic and drops connections constantly.

The app works reliably for me, but as others have noted is missing settings that the Emura heads have. These aren’t a big deal for me; I’m not going to use a remote control like some kind of 20th century caveman. Settings also do not sync with the remotes. I have a large ducted unit connected to the same heat pump as the emuras, that uses a different Wi-Fi adapter and a different app. If you mostly run a schedule this again isn’t a huge deal. If you have a big, old house with no ducts, the daikin system is still the best game in town, but software is not their core competency. There is a community developed smartthings adapter that seems to work well, though I haven’t done anything fancy with it.

2022 update: the SmartThings interface still works, it’s unauthenticated and using port 80 on the local address, so it’s unclear why they disabled local control in the app because it’s still available on the units. Wouldn’t be hard to write a new app; I’m working on SmartThings rules automating switching between my nest controlled furnace and the heat pump based on available solar input and outside temp.

I have been struggling with this app for two plus years in every way described by the other reviewers. The app is still on version 1.0! I routinely have to reinstall each unit because the app cannot find them, and when it does work, the signal has to beam up to a satellite and back through my WiFi to each unit because the “in home” function does not work. It has never worked. And it’s not a problem with my WiFi because everything else on it runs effortlessly.

I wish I had gotten actual central air and just had the ducts built inside my home. At least it would work the way I need it to in the way I paid for. This now feels like a costly mistake. I will gladly amend this review if Daikin ever fixes the problem. Until then, I would not recommend using their products on WiFi. If you only use it when you are there to point and click the remote, and you have no animals or people at home who need you to manage the climate control for them, it should be fine.
