Is it available in the UK. Will purchase one before it gets out of stock. Just like the keypad, I think they have stopped producing it.

It is totally a new product why they will stop producing it ? Furthermore there is a lot of demand in Europe for this product.
Yeah, true tho
Firstly happy xmas all. Secondly, I have had an update regarding the siren not respecting the delay:
Dear Steve,
Thank you for your patience.
Thank you for the information.
Our engineer realized the issue and they are working on a new firmware to fix it.
It may take a week or two for the fix.
I have issued a full refund for your order.
Please allow 2 to 4 days to receive it.
Apologize for the frustration caused.
Have a good day.
No shipping to the Netherlands (normally via EUFY Germany) 
Hi, i have good news for European Users.
The siren will be available in February (Eufy told me by email). If you cannot wait,it is available on Amazon DE and they are shipping to France :
Quick update on the siren delay issue. They’ve identified it’s an issue with the app itself so a new version of the app should be released in the next week.
Thanks for the update, sounds like it’ll hopefully be resolved soon.
Any news on this?
I see there is a new firmware for the Homebase.
Not seen anything new my end yet. Still waiting sadly.
Likely to never get fixed. And then the product will be withdrawn
My Homebase updated today and when I opened the door, the siren didn’t go off until the delay had passed.
Took them a little bit but glad to hear its finally fixed. What version is your home base on now and were there any release notes?
as of 15:24 its on 3.3.2.6h. No release notes that’s I’ve seen.
I’m a in the UK. My homebase 3 is on 3.4.2.3.
A even later version, yet the siren goes off as soon as door is open. No delay
Mines a Homebase 2. The fw updated at 15:24 on 23/01. What’s the date of your fw?
Mine is also on 3.4.2.3. Apparently there is a more recent homebase 3 firmware thats needed to fix the alarm delay issue. I have sent an email to Eufy requesting they push the most up to date firmware to my homebase 3 including its serial number. I suggest you do the same if the new firmware isnt available to you yet. You will also need the Eufy Security app on 4.8.0 as well.
The siren is available in amazon FR but the comments are very bad. The fact that you can change the type of alarm is one of the negatives point. Furthermore 105db is apparently not loud as expected. What a waste of time for a product that Eufy’s users are waiting for years… if we check some others products (not eufy brand) the siren is at least 110db. My neighbors have Ajax security (112db) and we can hear the alarm… i am very disappointed on this product.
If it is not possible to get a good quality siren, is it possible to have a wireless relay to be able to mount any actuator? Thank you
I’ve previously created a post asking why the now Homebase 3 connected Wall Light Cam isn’t shown in the app “Automations” section.
It also had me thinking.
The S100 has a 105db alarm fitted and flashing lights. So if it was configurable in Automations you could have any sensors as triggers to make it the outdoor siren component of the alarm system. As well as triggered recording for anything in Automations.
It’s a hard wired unit too, so no charging of batteries!
