What is the (technical) reason that the Atag one app from Marcel Timmerman no ​​longer works on the new Homey Pro 2023? It must be possible that an app that has been used for years on the old version can be easily adjusted so that it also works on the new version. I understand that it is not an official app supplied by Atag, but someone from the homey development team should be able to adapt the existing app from Marcel Timmermans so that it also works on the 2023 version. ---

Hi Henk, Most apps have their own topic, thanks. There’s a chance you’ll find info in that topic about the status (none, abandoned, open to transfer and such). You’ll find all support info at the bottom of the app store app pages: > ![Screenshot from 2023-10-18 02-43-11](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/4/f/4f41caa08e710093c3bdb9e43d498b348b91f8e2.png) If you want Athom to check with a long time (let’s say 12 months) unresponsive developer, I think writing to support is the best option [https://homey.app/support](https://homey.app/support) Chances are quite small I think. ---

I understand that it is not an official app supplied by Atag, but someone from the homey development team should be able to adapt the existing app from Marcel Timmermans so that it also works on the 2023 version. Athom doesn’t have enough manpower to update every outdated app. Besides that, there can be copyright issues, you can’t always just take someone else’s code and change it. ---

@HenkS as you can see in the app support forum topic there are more users requesting this. > [@\[APP\]\[Pro\] ATAG One app](https://community.homey.app/t/app-pro-atag-one-app/7005/26): > > Ik zou graag met de ontwikkelaar in contact willen komen zodat we voor de HP23 ook ondersteuning kunnen krijgen. Zou graag mee willen helpen met de ontwikkeling hiervan. As stated above I think it’s your best change to get heard, but if someone is listening…… 🤔 You can also download the code from GitHub, make the modifications yourself and install this via cli method 👍 > [@\[HOW TO\] CLI install method](https://community.homey.app/t/how-to-cli-install-method/198): > > Homey Pro only!!! It does not work this way with Homey (cloud), it only supports CLI run which is there only for development purposes. Installing Node.js Check Node.js version on Homey: Homey App: Settings - General - About - Node.js version Download Node.js (use Homey’s version or higher) from [https://nodejs.org/](https://nodejs.org/) and install it on your computer. Download the app you want to install from GitHub Go to the repository on [GitHub](https://github.com/) (the correct link for the app you want to install is at the bottom… This is how I modified this app a few years ago.
