## Newest reviews (3 of 16)

### 1/5 — Very poor

*2021-10-24, version 1.5*

Constantly crashes and intermittently refuses to communicate with the radiator. Actually feel like it’s worse than when I first installed. Pls fix!!

### 1/5 — Not great

*2021-04-30, version 1.5*

I’ve tried installing and reinstalling the app many times. It won’t connect to the router. Not happy with this app. Not happy with this expensive system.

### 1/5 — App not working

*2021-04-02, version 1.4*

We rely on this app to control our heating in a holiday let. It has now not been able to connect for several weeks, leaving us unbeknown to our heating levels at the property.

## Most critical reviews (10 lowest-rated)

### 1/5 — No longer working

*2025-12-29, version 1.5*

This app no longer works with my Thermotec radiator

### 1/5 — Not connecting to server

*2025-11-06, version 1.5*

This app continually crashes or doesn’t connect. It’s now  connecting to server at all and keeps looking for an alternative server. I cannot set my rads remotely which is very frustrating. Wish there was a different app I could use. Totally useless!

### 1/5 — Upgrade dringend nötig

*2025-10-28, version 1.5*

Leider ist hier keinerlei Fortschritt erkennbar. Alle Funktionalitäten benötigen dringend eine Weiterentwicklung

### 1/5 — Wenn es läuft gut, aber leider zu oft keine Verbindung zum Server

*2025-10-14, version 1.5*

An sich eine gute Idee, aber leider ist die Verbindung zum Thermotec Server zum wiederholten Male einfach weg und beim Versuch den Ersatzserver zu erreichen bleibt die App in einer Endlosschleife hängen. Damit ist eine externe Steuerung der Heizungen nicht mehr möglich. Im WLAN zu Hause geht es, aber da kann man die Heizungen auch manuell einstellen. Leider Enttäuschend.

### 1/5 — App crashes consistently

*2024-01-01, version 1.5*

App crashes almost every time we try to use it. Also, it cannot connect with one radiator  consistently so we have to manually control it. Not worth the money - do not use!

### 1/5 — Needs a massive upgrade

*2023-12-17, version 1.5*

I wish I could use a different app. Alas my electric radiators seemingly only work with this one. The app crashes 9 out of 10 times I try to use it.

### 1/5 — No stars

*2023-12-03, version 1.5*

Kept disconnecting, so uninstalled app to set up again. Now it will not sync with the smart heat module.

### 1/5 — Useless

*2023-10-18, version 1.5*

Spends more time disconnected from the radiators so can’t control from the app, pity there aren’t - stars

### 1/5 — App don’t work

*2022-09-18, version 1.5*

I have spent over 3 1/2 hrs trying to connect to this app, Crap don’t use. Better off using controls on heaters manually

### 1/5 — App and kit not compatible

*2021-12-08, version 1.5*

I’ve bought a Wi-Fi router with heaters. It says to connect to this app. As I enter app it asks me to press the button on the back of the router to be able to connect. There is no button and it’s now unusable. Awful. I want my money back.

### 4/5 — My heating app

*2025-11-23, version 1.5*

Our heating app has been working for a few years but now the app doesn’t,tconnect to the WiFi properly you have to stop and start it .

### 3/5 — App is a bit dated now.

*2022-11-24, version 1.5*

I have had been using this App for four years now in a home environment and haven’t really had any issues apart from the occasional loss of connection which is easily rectified but restarting the App.
It is quite a basic basic App and could do with some additional features such as, show status/ temp of all rads on one screen.
A logging feature to log the temp of a zone over a 24 hour period. Which would be handy for checking the temperature of a room when the Brad’s are off.

### 2/5 — Where is the Alexa integration?

*2019-10-21, version 1.3*

Supposed to have an Alexa integration but I can’t see it anywhere. 
The rest of the app is ok but pretty basic. 
Something that tells you if the radiator is on, or drawing power would be nice. So would a home screen that shows all room/zone temps without having a select each one... but fix the Alexa bit first as there is nothing under the wrench/spanner icon like you say there is.
