Mr

Very nice and smooth

Daikin air conditioning

The Daikin air conditioner is working amazingly well

Connection issues

Have to revert to the remote most of the time. Connection keeps dropping.

The app is ok so far. Connecting the units to the app is soul destroying

If your installers connect to the app for you then the app functionality is fine. However with my last Daikin air con system I had to reconnect them a number of times for various reasons, changed Internet, app updates etc, till I finally gave up trying. I’ve just installed the same units in my new house, the first unit only took about 15 minutes and 2 attempts. The second unit took 40 minutes and 5/6 attempts. I’m considering the 3rd unit with dread whilst writing this review.

Too many bugs

Great App but frequently crashes & then have issues logging back in

Extremely poor

Doesn’t work well

App is down

The whole app system is down again. Cannot connect to gateway, token not valid, etc. please fix as we are having a heatwave currently !!

Not working now

Heatwave and the app isn’t working so can’t turn on units

Availability issues

The app goes down rather frequently. Most recently was an issue with the gateway timing out (no it isn’t my internet).

Shocking

Just keeps throwing me out lately nothing but issues with this clunky useless app that isn’t reliable can’t login again tonight as 504 bad gateway error message it’s a joke
Wished I had got a different make ! Of air conditioner

Not great

This is a very basic app to control very expensive air con units. It constantly loses signal with the units and getting them loaded back up is not easy at all. When you use the app to switch units off there is a time lag so you press the off button and the app shows it’s back on even though it’s switching off. Tonight there is no signal to the server and all my units are on in my children’s bedrooms so I can’t check the temp or see if they need switching off without waking them. Had these units since 2023 and the app has never been good. Shame because I was considering Samsung units and to be honest wish I had gone with them over Daikin

Awful

Useless

Good design but just generally poor

Constantly getting logged out and randomly not being allowed to log back in. Sometimes I have to completely reset my device. The overall design and function is good enough for me but the errors are just very irritating.

Last update breaks WiFi stability

Latest firmware update keeps making all 4 of my units show an intermittent network connection error. Very frustrating

Air con set up

Setting the app up was very easy , however connecting the units took for ever not very easy at all.
Once set very simple to use and prompt .

Amazing service and quality

Good but please add Timer Function

The app is generally quite good.. though it’s missing a timer function eg to turn off after X time. The schedule function does not allow for this adhoc timer ability.
Simple to do.. please add it

Very basic (controlling EDLA06E2V3)

For my air to water system it is very basic. I can’t amend or even see my heating schedule. I can’t boost the heating for a preset period, I have to increase and then later decrease flow temperature. I can’t boost hot water other than by triggering the immersion heater and then subsequently cancelling the immersion. If I know in advance that I’ll need more hot water I should be able to use heat pump heating to boost. Recent versions no longer show external temperature. There is no way to monitor COP. The granularity of energy consumption is very poor. (500W steps per 2 hours)
If using the app to manage other users it would be useful to see when they last logged on and even what they did.
Edit 2026:
I am getting update firmware messages in the app for the user interface (presumably the control screen on the wall) but it consistently fails to load, even when I have followed their linked “help”. I suspect my firewall but the site delivering the firmware is not published and ∴ cannot be added to my white list.

Apart from

The usual that you cannot set 0.5 degrees like others have mentioned the app (3.47.1) now consistently says the WiFi is weak. The main control unit is less than 2M away from the router and has never had an issue before. Nothing else in the house uses this router just the heating system! The router says the devices connected are at full strength.

Awful app

Got a new build house which had a Daikin Heat Pump with a gateway supposedly for online control.
Nope.
App is dreadful and doesn’t find the gateway. I’m fairly techy and comfortable using devices and Apps - this is an awful app and interface. Avoid.
