Closing the app often change the state of them. Please move them a little upwards. ### 2/5 — Katastrofen *2025-03-02, version 2.1.1947* Asi žiadna aplikácia má nevytáča tak ako táto. Chcem pridať teplotu a stačí aby som ťukol prstom len trochu mimo tlačítka + a termostat sa okamžite prepne do módu opustiť domácnosť…. A ani po toľkých rokoch to stále nie je opravené ### 2/5 — Non funziona più bene *2024-12-13, version 2.1.1947* Dopo l’aggiornamento passa direttamente nella situazione di fuori casa dopo l’accesso. Va nuovamente aggiornata. ### 3/5 — apple home *2024-03-25, version 2.0.1873* Can it be added to apple home? ### 1/5 — Outdated app *2023-10-26, version 2.0.1873* This app needs an urgent update! So sad because siemens thermostat is an excellent device ### 1/5 — Servers is down. *2023-06-17, version 2.0.1873* Maybe the server is down. I'm not able to connect. I have done everything. Nothing works. ### 1/5 — Pls correct & update *2023-02-08, version 2.0.1873* It often loses its defined screen size in my mobile and have to delete app and reload in order to be able to use it. An update version is eagerly required! ### 1/5 — Unacceptable *2023-02-05, version 2.0.1873* The app accitendatly turns off or on the thermostat when closing the app. This results in either a house that is heated when is not necessary (at great expense) or in a house that is cold when should be warm (ruined ski weekend). This only why the switch is positioned at the bottom and does not ask for confirmation! Moreover the scale is completely useless as it does not zoom in at the actual temperature, it always shows the full range. ### 1/5 — Association with account not working *2023-01-23, version 2.0.1873* Thermostat disappeared from the account!!! Tried to associate it again with the existing account several times but activation code is not working!!! Contacted the customer service in Greece since one week and still no answer from them. Pity!!! ### 1/5 — Viele schwächen *2023-01-08, version 2.0.1873* Auf meinem Iphone 13 ist laufend die Anzeige auf einen schmalen Teil am linken Bildschirmrand reduziert und nur durch einen Neustart lässt sich das beheben. Von Siemens könnte man mehr erwarten, ich hoffe das es schnell einen Update gibt. ### 1/5 — Lamentable *2022-12-30* Falla mas que una escopeta de feria ### 1/5 — Constantly offline! *2022-12-29, version 2.0.1873* Bought an RDS110 payed over 200 euros to be able to use the device remotely and it is almost every other day offline!! Siemens fix this!! What is very disappointing is that I read so many other users having the same problem for the past two years and you have done nothing to resolver the matter! ### 1/5 — switch placement on screen *2022-12-28, version 2.0.1873* în the smart thermostat RDS app the switch between at home and away is too close to the bottom of the screen and when moving to another app or to home screen it accidentally triggers a change in state from at home to away or away to at home. please raise that button on the screen. ### 2/5 — NO connection to iPhone *2022-11-17, version 2.0.1873* Worked well for the first years. But after summer, during which time the hearing was turned off, although the house unit works fine, it does not connect to the App !! Eagerly waiting for an update of the App!! ### 2/5 — iPhone APP *2022-04-09, version 2.0.1873* When closing the app most of the time the slide button goes to Away!!! Can you move the slide button a little higher from the bottom of the page? ### 3/5 — Bedienung *2022-03-06, version 2.0.1873* Leider kommt man beim “Schließen” der App sehr oft auf den Schieberegler Home - Away. Man muss die App auf der Seite der gewünschten Einstellung schließen. Wenn man nicht aufpasst, verändert man ungewollt die Einstellung. In der IPAD App funktioniert die dritte Seite nicht. Man kommt auch nicht auf die erste zurück. ## Most critical reviews (10 lowest-rated) ### 1/5 — Not working *2026-02-25, version 2.1.1968* The app is not working anymore… ### 1/5 — Si sconnette sempre *2025-11-05, version 2.1.1947* Dopo essere riuscito a collegare l'app al termostato perde dopo poco il collegamento. Ho scaricato di nuovo l'app da Apple Store vaie volte ma continua a scollegarsi. Utilizzo la versione 2.1.1947 con iOs 18.6.2 Potete provvedere? ### 1/5 — Not working *2025-01-02, version 2.1.1947* The device disconnects for no reason ### 1/5 — Katastrophe! *2024-07-26, version 2.0.1873* Die App ist leider nicht mehr nutzbar, eine Anmeldung ist nicht mehr möglich. Das Passwort kann nicht mehr zurück gesetzt werden ! Der Support ist nicht erreichbar . Die Entwickler Seite ist nicht erreichbar ! Ich dachte ich habe hier ein Produkt eines Namenhaften Herstellers gekauft die 600€ für die 3 Thermostate sind wohl für die Tonne wenn Man die App nicht nutzen kann hätten es auch welche für 30€ getan sorry Siemens das ich enttäuschend. ### 1/5 — Unstable app - can’t be trusted *2024-05-02, version 2.0.1873* Swiping up to get out of the app (iOS) will often change the status from “Home” to being “Away”! Also: the mode changes by itself for no reason. What is going on here? How can I stay warm when the app keeps changing what I want the temperature to be. Horrible!!! ### 1/5 — It used to work fine *2024-02-12, version 2.0.1873* Now constantly the device disconnects for no reason. Given the cost to by the thermostat I would never ever buy this device again. ### 1/5 — Very poor *2023-12-06* Tricky to program and won’t let you set temps below 12 degrees. Easy to swipe app closed in On position by mistake. OK if you don’t mind big bills. ### 1/5 — Bad app *2023-11-23, version 2.0.1873* Unstable app! I have to close it and run it again!! I shouldn’t buy the Siemens RDS110 and.. This is a very poor app for Siemens.. That’s a pity! ### 1/5 — Home screen *2023-11-20, version 2.0.1873* If you have more than one thermostat on your home screen, you cannot see the status of its thermostat. You have to click one by one in order to see the set it and the present temperatures. ### 1/5 — Shame… *2023-11-03, version 2.0.1873* A very expensive thermostat, which reset one time a month! That’s Simens? ## Most praised reviews (10 highest-rated) ### 5/5 — It works well!! *2023-11-24, version 2.0.1873* Easy setup and easy to use. ### 5/5 — Ottima app *2021-12-20, version 2.0.1811* Dispositivo perfettamente funzionante e di altissima qualità, app ben funzionante peccato che non è compatibile con Apple HomeKit e Google Home ### 5/5 — The app is great but desperately needs 3rd party integration *2020-10-02, version 1.17.4614* I purchased this thermostat as it was the only smart thermostat on the market that supported our 240V Australian power supply. I love the app but the inability to control it with anything else is a huge dealbreaker. I have went through the ClimatixIC developer API and the documentation is extremely confusing. For Siemens, the development of this platform seems like an afterthought with even KNX products being far more “smart.” I would even like a better API or KNX integration to work with smart home systems, making the system far more appealing. For a 600 AUD product the lack of ANY 3rd party integration or somewhat decent API seems absolutely staggering to me with non-smart branded Siemens ovens working far better with platforms such as Home Connect. The app might be good but Siemens lack of any functioning API or 3rd party support is nothing short of astonishing. ### 5/5 — Rds110 *2019-06-18, version 1.14.338* Cette application est vraiment aboutie et réussie Très facile d’utilisation Bcq de possibilités avec une utilisation très facile et intuitive J’ai déjà fait 21% d’économie sur mon chauffage Au top Siemens Du vrai produit « Deutsch qualitatif » ### 5/5 — Really good app *2018-01-01, version 1.9* Iphone x support is coming?:) ### 4/5 — Verrouillage du chauffage *2024-03-01, version 2.0.1873* Bonjour Je me permets de vous contacter car je cherche s il existe une solution pour bloquer les changements au niveau du boîtier et ne pouvoir modifier la température qu au niveau de l appli. Merci d avance ### 4/5 — Bug on iphone *2023-01-30, version 2.0.1873* There is a bug on iphone. Buttons “At Home” and “Away” are too close to bottom, and they switch on each other when you try to close the app. Tested on iphon 14 plus. ### 4/5 — Bene ma non perfetto *2022-12-13, version 2.0.1873* Da qualche giorno non riesco più a restartare i singoli Termostati dall’iPhone, il resto funziona da remoto ma il restart no, che sia un bug software? A quando l’integrazione con Google?! ### 4/5 — Ανανεωμένο interface *2021-10-08, version 2.0.1763* Στην τελευταία version όταν επανέρχεται από το background στο foreground εμφανίζεται σε πολύ μικρότερο μέρος της οθόνης μερικές φορές. Κατά τα άλλα σαφώς βελτιωμένο. ### 4/5 — Heating demand meaning? *2020-11-18, version 1.17.4614* The heating demand graph does not correlate to the hours the relay is working. It shows ( as far as I uderesrand ) the hours below the targeted temperature +0,5 *C. That does not mean that the relay is always open-working during these hours, due to the algorithm. How can I know the hours the relay is energized? Could you make such an addition? --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
