Hi all, I am thinking of buying this outdoor siren: [Siren/Outdoor Siren-VISION AUTOMOBILE ELECTRONICS INDUSTRIAL CO., LTD.](https://www.visionsecurity.com.tw/index.php?option=product&lang=en&task=pageinfo&id=392&belongid=324&index=0) Does anybody have any experience with it and Homey Pro? In an old post from 2019, is mentioned that it doesn’t work with Homey - but another post from 2020 says, that it does? Any help appreciated, thanks. Kind regards Finn ---

If type 1621-5 is type 1621 it is supported by [Vision Security App voor Homey | Homey](https://homey.app/nl-nl/app/com.visionsecurity/Vision-Security/) I have no idea what the “-5” means. If it is part of the type, it will not work. For types see [VISION ZM1621MY-5 INSTALLATION & OPERATION MANUAL Pdf Download | ManualsLib](https://www.manualslib.com/manual/1479402/Vision-Zm1621my-5.html) ---

Hi RMB, Thanks a lot for your swift reply 🙂 I also have no idea what the “-5” in the type name means. And looking through the “Vision ZM1621MY-5 Installation & Operation Manual” doesn’t seem to help. I don’t want to buy it, if it doesn’t work with Homey. Actually it is pretty hard to find an outdoor wireless/battery operated siren that works with Homey! The only one that I could find is the POPP siren: [POPP App til Homey | Homey](https://homey.app/da-dk/app/com.popp/POPP/) (Solar Outdoor Siren 1 & 2 005107 & 700854). But it needs sun, and cant be installed in the shadow… If anyone knows about an outdoor wireless/battery operated siren that works with Homey, please let me know, thanks. Kind regards Finn ---

Appearantly everything after ZM1621 indicates the country code. ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/6/0/60797c38488b5f52eacef7315f744354900b6b0a.jpeg) > **[Siren/Outdoor Siren-VISION AUTOMOBILE ELECTRONICS INDUSTRIAL CO., LTD.](https://www.visionsecurity.com.tw/index.php?option=product&lang=en&task=pageinfo&id=392&belongid=324&index=0)** > > Vision is a global leader in design and manufacturing of wireless control technology.

once again RB, thank you 👍 I found this support thread about the Vision app for Homey: > [@\[APP\]\[Pro\] Vision Security](https://community.homey.app/t/app-pro-vision-security/44945): > > Vision Security Add support for Vision Security in Homey. Supported Devices ZD2102 Door/window sensor ZP3111 4in1 sensor ZP3102 PIR motion sensor ZG8101 Garage door sensor ZM1601 Battery Operated Siren ZM1602 DC/AC Power Siren Note This app is ready for V5 and is transferred to a new developer (Martijn Poppen) Supported Languages: uk Englishnetherlands Dutch Contributions If you appreciate this app, contribute to future development by making a [paypal contribution](https://www.paypal.me/martijnpoppen) or … Maybe I should have posted my question there instead? I’m new to Homey and the support forum, and on a steep learning curve 🙂 However, reading through this thread, I could not see any unambiguous proof that the Vision app for Homey supports the Outdoor siren ZM1621-5?
