### 1/5 — Constantly glitchy

*2026-05-31, version 1.2.6*

I have to constantly shut down and reopen the app to get it to connect to the thermostat, it never works when connected to our WiFi so I usually have to disconnect from it and often we have to reboot the entire system to get it to connect at all. No developer update on this useless app in 2+ years despite the poor reviews says it all.

### 1/5 — Kann das mal jemand aktualisieren?

*2025-10-17, version 1.2.6*

Diese App soll eine Wlan fähige Fussbodenheizung steuern. Sie stürzt aber ständig ab und die Einstellung funktioniert nicht. Selbst der Techniker ist daran verzweifelt. Kann so nicht bleiben!

### 5/5 — Geniale App

*2025-09-22, version 1.2.6*

Einfach perfekt

### 1/5 — Відгук

*2025-04-07, version 1.2.6*

Ну краще б взагалі не було додатку, ніж такий

### 2/5 — The app

*2025-01-24, version 1.2.6*

What an absolute failure. For three years I’ve been struggling with this app. Do not recommend.

### 5/5 — Essential Feature Missing: Custom Commands for iPhone

*2025-01-13, version 1.2.6*

While the DEVI Smart app is user-friendly and efficient for managing thermostats, it lacks an essential feature for iPhone users: the ability to create custom commands. Integrating Siri Shortcuts is a step in the right direction, but the functionality is limited. A built-in option to create and manage personalized commands within the app would significantly enhance the user experience, especially for those who rely on automation. Adding this feature would not only improve convenience but also make the app more competitive in the smart home market.

### 1/5 — Dramat

*2025-01-08, version 1.2.6*

Najgorsza aplikacja do zarzadzania systemem domowym jaka widzialem. Niestety jestem na nia skazany, bo mam zamontowane termostaty Devi. Termostaty non stop sie rozlaczaja z sicia i aplikacja, dodawanie ich od nowa to droga przez mękę. Sama aplikacja jest zrobiona tragicznie, totalnie nieintuicyjna. Zrobiona bez zadnego udzialu spacow od UX

### 1/5 — Terrible app

*2025-01-04, version 1.2.6*

When in manual mode, so I can use when I want, the app is completely useless. The interface tells you nothing. Imagine looking at a clock to see the time but you have to select a little clock symbol first. Welcome to this app. To see the temperature which is the fundamental reason you have one, you have to select a side option!!!! Ridiculous. Interface poor, no thought. Very confusing too.

### 1/5 — Very poor

*2024-11-14, version 1.2.6*

This has to be the most unintuitive app - just awful for something that a child could program.

### 1/5 — Truly dreadful

*2024-10-28, version 1.2.6*

So bad. Would never install a Devi floor again based on this App

Rename kWh to W in About thermostat for output
iOS 13 setup issue
