Eufy should add a wireless switch to the system. Then anybody can connect any siren or light to it.
Eufy Siren
@Tank Any update on this at all I just bought a system and need one as I’m in trouble with insurance otherwise lol
Should we have a birthday cake on December 2022 for the 3 year anniversary of this idea? Or will it be delivered this year?
May be a small cake would be helpful to convince the “chef engineer” ! 
So from what I got from the project manager for Eufy, he supposedly never said a siren was coming. When we know they did and so now I doubt we will ever see one

I agree with all the comments above - this is an essential requirement.
Happy to pay for an external siren.
Already have 2 x Homebase2. Why can’t they talk to each other?
I bought other Eufy cameras and external siren and … they don’t talk to HomeBase.
Needs some updates !

This was a post from 2019 and Eufy still has not picked this feed back up. The current siren is not even audible outside from the inside. This draws no attention or panic. This is a simple piece of hardware which almost ALL Eufy security owners will buy. this is a huge revenue opportunity!
@eufy how often do you have customer asking you to make more revenue!
The person who sold me this product in the store said it was very loud. After hearing it sounds like a toy firetruck going off and i feel scammed. I dont really want to sit and hope for an external alarm to come out SOON. Its a shame because everything else seems ok. The issue is if somone turns our power off from outside then the camera will stop streaming and can be destroyed the alarm going off is all thats left. Also the alarm going off is what stops the theif from going through your home thoroughly and finding all your valuables instead they have to go for a quick grab. This alarm will not create that hurry as im certain not even my neighbour heard it and he can hear me cough at night. Im seriously considering returning the product.
I think a great option would be to have the possibility to link all Alexa echo and other compatible speaker around or in the house to the alarm. So they all play the alarm simultaneously everywhere.
I have actually done this, but the downside is you can only add an activity based on a window or door sensor, or a camera. You can’t trigger with a motion sensor. I have a routine created that announces “Motion detected - please provide voice password within twenty seconds.” And then after that I have a routine that announces “Password not entered - dialing local authorities and notifying designated account holders.”
I’d much rather have a good old fashion siren and strobe though, like everyone has been nicely asking for in this stream!
