Navien Smart Plus

App not working since update

Water heating not being timed

Energy usage doesn’t work

Loses info - history

Glitches so all of a sudden it goes into holiday mode

Holiday doesn’t work

Cannot turn holiday mode back on through the app

App very temperamental and typically requires the app to be fully closed and restarted

App is awful, boiler inefficient and unreliable

Out of action more times than it’s working

Very temperamental boiler and the APP is very annoying and unreliable

Timer on the app is awful

System has a fault, only way to know is when heating hasn't come on or error code on thermostat

Needs to be improved, have to keep logging out and back in to get working

Unreliable, slow and often does not work

App glitches a lot

Data and graphs don’t work

App no longer works

App won’t load

Horrendous app

Schedule interface is ridiculously contrived and difficult to work with

Boosts don’t have durations

Thermostat has a mind of its own

App is constantly crashing when clicking on it

It won’t even open

Horrendous app constantly down

Constantly crashes

Doesn’t even allow you to log in

Unusable app

App says ‘loading’ and then changes to ‘offline’

App doesn’t get updated

Half the features don’t work

Can’t even sign up and make an account through the app

Keeps telling me my two passwords don’t match THEN tells me I have an incorrect password

Attempted to log in using both different passwords and obviously tells me I don’t have an account

Doesn’t work. App crashing all the time

Tried reinstalling app. But still doesn’t work

App won’t open

App has completely stopped working

Instantly closes down when I try to open it

Doesn’t work or function reliably

App says ‘offline’ when everything else is working fine

App does not work

Smart control of our central heating isn’t possible

App says it’s offline even though the boiler control module says it’s connected to the wi-fi and the server, and is working correctly

Re-connecting the control module to the wi-if multiple times and deleting and reinstalling the app hasn’t resolved the issue

Latest Update: app has just stopped working

Infuriating to use

Each time you load up the app you must force close the app and restart it to view the thermostat or to change any settings

Connects to my wifi but won’t connect to the internet

Terrible app

Almost useless

Constant issues connecting

Glitchy

Could use some work

Not updated in ages

App keeps crashing when trying to change oil usage

Very very poor

So many bugs with it

Developers can’t be bothered fixing them

App on my iPhone 11 doesn’t work

Won’t keep my location

Constantly have to re enter all info to get it to work

Geo fencing never works

Fuel consumption never work dispute constantly putting the Corcyra setting in

App was difficult to set up

Wouldn’t connect to my wifi during my first attempt at registration

Didn’t recognise the serial no of my boiler

App always says offline when I open it

Takes some time to connect

Says off;one when it has two blue lights and is online

You have to wait 20 seconds for it to reset then shows online

My temperature is set to 22 degrees but the app shows 0 degrees setting yet the boiler fires up as it should

Can’t put in special characters in password & doesn’t inform you this

Translation labels don’t match up

Connecting shows “network issues” but if you spam tap the button it’ll work

Repeat all these steps every time because the account doesn’t persist

App needs fixing as keeps shutting its self down

Hot water program options has been removed and you can only program heating on the app now

Shows as offline constantly

Constantly resets itself to whatever it likes

Temperatures bear no resemblance to those we input

Eg will always reset Tuesday to have temp of 32c at 7am, no matter how many times we set it to a normal temperature

Constantly goes ‘offline’

Useless as a way of controlling the boiler

There’s some sort of bug which means you can’t input the password to set up the account

Constant need to exit the app and then reopen otherwise it says “ offline”

Geofencing doesn’t work since it cannot identify my location

Oil consumption not updated daily

If an “E002” error appears on room thermostat it is not replicated in the app

The setup process for this assumes that everything will go smoothly and look exactly as it does in the pictures

If it doesn’t, there is no way to skip the setup process or sidestep to get help

There’s no apparent “Wi-Fi button” on it

The process for pairing it with the app must differ from the directions provided, but there’s no other guidance of any kind available

Constantly says ‘offline’ so you have to close and reopen until it connects

Scheduling is totally non-intuitive

When you click on another day, it annoyingly automatically reverts to the Monday

The app does not stay connected

Comes up with check internet connectivity, there’s nothing wrong with my WiFi

When I turn the heating down using the app, it resets itself back up again within a minute or 2 and the heating turns on again

It only stays off if I use the RF control instead

App used 43% of my battery in 3 hours while running in the background

App needs to use the same type of GPS usage as an actual navigation app

The only way to stop it is to kill the app

Poor design and usability

Written in broken English in a variety of fonts which hurts my head

Control options are confusing and not intuitive

Operationally works fine with the boiler but could look better
