Hey! I have been searching the forum regarding this topic. Sadly most of them have different specs or are not what I need help with.

So I have been looking at more sirens alredy, both Aeotec and Netatmo. From my point of view Netatmo is the best, but sadly not working with Homey.

I need a siren that runs on battery and are working properly with homey. I need to be able set it up with flow for both fire detector and also dor/window sensor

Btw I also have a Tp-link camera I cant connect as they are not suported. I have still tried with Onviz app, as some have made it work with that app. I find there also, i just cant connect it. Probably because te port is different on tp cameras.

Thank you!

Please ask for support in the [dedicated Onvif app topic](https://community.homey.app/t/app-pro-support-for-onvif-compatible-cameras-release-2-0-41/28377), I’m sure it is solvable, when the TPlink cam supports the Onvif protocol ofc.

When that combo does not exist, just make a dumb battery powered siren smart with, say, a [Shelly UNI](https://kb.shelly.cloud/knowledge-base/shelly-uni). It’s a tiny WiFi relay and supported by Homey.
