Dear all,  
my siren 6 worked perfect with the Heimdall app. After Aeotec update (3.6.3; 2 months ago) the siren 6 remained silent upon a home alarm but the blinking light can still be triggered by an alarm.

Ive tried a couple of usual approaches for a solution;

- checking the power; Siren 6 is powered 230V - battery is 100%,
- removing and installing Aeotec app and Siren 6

But without any result 8-(

Does anyone recognize this problem, any idea on the solution(s)?

I use Homey software version 7.4.1  
Heimdall 2.1.6

Thanks a lot in advance!  
Niels

I don’t own a siren 6, but there seems to be a known issue in the Aeotec App, please have a look at the [Homey App Changelog Link](https://aeotec.freshdesk.com/support/solutions/articles/6000245694).

My recommendation is to contact Aeotec: [support@aeotec.freshdesk.com](mailto:support@aeotec.freshdesk.com)

Btw, the Heimdall app has no influence of the function of the siren 6.

@ fantros, thanks for your response; I’ll contact the Aeotec’s support desk and come back with, hopefully, the solution 🙂

Hi, was this solved? I am thinking of buying this siren.
