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?

Kind regards  
Finn
