Can't connect the POPP 700342 10 Years Smoke Detector to Homey Pro

If there isn’t an app especially for these smoke detectors of this company in the app store, then the chance is very low that these devices are currently supported by Homey.
Each Z-Wave device has a manufacturer ID, product type ID and device ID. If these IDs are not present in any app, then the devices are added as “Generic Device”.

You can write your own App or make an app request in this thread. But I guess the chance that someone will develop an app for these devices will be really small, sorry.
