Hi there, am I the only one to be interested with having an Atlantic Cozytouch app ? Cozytouch is a bridge allowing control of different devices from the Atlantic company. (Heater, towel driers, water heaters etc…). As these devices are connected, it would be great to have these in homey ! ---

On this page you can do a request if there is someone who can build an app. [https://community.homey.app/t/homey-pro-community-app-requests/2713](https://community.homey.app/t/homey-pro-community-app-requests/2713) Please read first what kind of info you have to add to the request. ---

As an interim / workaround I will be exploring [IFFT with cozy touch](https://ifttt.com/connect/ATLANTIC_Cozytouch/homey). Needless to say, I won’t be spending much time on it as the Cozy App itself has for my applicance (Atlantic Explorer V4) very very basic functionalities only ---

Hello, I created a Homey app that supports some Atlantic / Sauter / Thermor products through Cozytouch, using the Overkiz and/or Magellan APIs depending on the product type and its age. It is heavily inspired by the app developed for Home Assistant by a member of the community. This is still a very unstable version, and I cannot confirm that it works properly for products I do not own. At the moment, it is working in development mode for Kelud / ASAMA (towel warmers) and Calypso for thermodynamic water heaters. If there are any volunteers with some development skills who would like to be alpha testers, you are more than welcome! Here is the GitHub link → [NicolasYDDER/homey-cozytouch](https://github.com/NicolasYDDER/homey-cozytouch). I will try to submit the app to Athom soon. ---

Hi Nicolas, I have 2 sereins premium towel dryer and would like to support you. I don’t have particular knowledges in coding or else, but with Gemini I was able to implement homey scripts to use my A/C in homey. And it was working. Will follow you on GitHub. ---

Hi @blutch32 , I tried to added Serenis Premium towel heater into the app. I cannot test it directly. What could be the best approach is to try to launch the app in developper mode (with docker following the readme of my Github) [NicolasYDDER/homey-cozytouch](https://github.com/NicolasYDDER/homey-cozytouch?tab=readme-ov-file#step-5-test) Then the app will appear in your Homey mobile phone and you can add a new device. After authentication to cozytouch login you will see your product. Then get back to you PC and share to me, from the debug log the modelId our the uiClass + the full log. We can continue the discuss in private message if it’s simpler BR Nicolas Y. ---

Many thanks for working on this app @Nicolas_YDDER ! I’m looking forward to seeing the Malicio 3 being added to the device list! Thanks ---

Hi @groteberg , I will be really happy to add it to the list of device. But it’s a resistance water heater (not thermodynamic), it likely uses a **different Overkiz controllableName** (e.g. `_CE_IOComponent` instead of `_CETHI_V4_IOComponent`) and may use different commands (e.g. `setDHWOnOffState` instead of `setCurrentOperatingMode`). If you are confortable to add the app in development mode and get me some logs, I will be very happy to add it. BR Nicolas. ---

Hy Nicolas, Thanks for the Great work! Will the Atlantic explorer v5 200l be supported in the future. For now homey says there are no compatible devices when I want to add my boiler. Keep up the Great work. Kind regards Erwin ---

> [@Erwin\_Platenkamp](#): > > Atlantic explorer v5 200l Hi @Erwin_Platenkamp , thanks for your support! The **Atlantic Explorer** might already be technically compatible, as it is very similar to the **Atlantic Calypso** (Wi-Fi version) which we already support.

Maybe a stupid question. But i can’t add my device. In the options of the app i fill in my credentials. It says that my account is connected well to the cozy touch magellant and there is 1 device connected. But when I want to connect my device to homey I select the app and it says there is no compatible device to connect. It doesn’t matter which category I choose from. I fill in the same credentials as I the options of the app. Then it says no compatible devices found. What I’m doing wrong here? Kind regards Erwin ---

Hi, I just added your app to my self hosted server, I am able to add the app and configure it. When I test connection, it tells me that it is connected. When I add devices, it asks me again to login and then find my 3 Sauter Malao heater. But once it is added it is unable to get or set anything on those devices. Any help please ?
