@fastriker they are so lound with this piezzo speaket you can hear them from 120m distace that i can confirm. 😂

Yeah that link switches to .us domain for me and shows me $17.10 / 2 pieces.
My link is 1 piece ($4.09 USD), 3 piece ($12.06), 6 piece ($23.81).
Try looking for "Water Leak Alarm Store" as the seller. I think this might be the link for store page:
https://www.aliexpress.com/store/1101889834?spm=a2g0o.detail.1000007.1.4ee610f3es4deG

Hi the aliexpress link provided in the readme is working for me. You can also search for "door sensor 433 mhz" and compare photos on aliexpress to the housing in the "photos" folder for this repository.
Were you able to find a similar looking sensor?
from reedtripradio.
Maybe it is some kind of geoblock. I have found one wich looks like the pics but is much more expansive.
from reedtripradio.
You might have to change quantity to one. What's your link?
from reedtripradio.
This one
from reedtripradio.
I also have a single spare sensor I could ship if needed.
from reedtripradio.
Nope sadly for me the Shop have No listed Item. Thanks for you support i will Go in searching and come Back to this issue with a link.
from reedtripradio.
Someone posted this link under the hackaday article. There the sensor is called GS-WDS07.
But if I search for it on aliexpress I only get one rather expensive result. A search on google give quite some results but mostly the sensors are not available anymore. My guess: They are not produced anymore :(
from reedtripradio.
@evilknivel Does this link work any better? https://www.aliexpress.com/item/1005003523731992.html
It's the same as sent by @mightymos but with no extra parameters in the URL.
Right now, shipping to Belgium is free and one item is 4 euro 89 (as of pre- hackaday article).
from reedtripradio.
I am not @evilknivel but I can not open the link "Sorry, this item's currently unavailable in your location.". I am in Germany and I guess @evilknivel as well, because he posted a German aliexpress link. I also changed shipping to Belgium - still the same. Maybe a VPN works? Unfortunately I have no VPN in another country available right now.
from reedtripradio.
@fastriker Sorry mate, VPN won't help: If I change the shipping country from Belgium to Germany, I get a "Page Not Found", so it looks like the seller won't deliver to Germany for some reason.
from reedtripradio.
@fastriker yes i am from germany, too. So Looks like we german are unlucky today.
from reedtripradio.
@evilknivel scheint so :(
@zindy thank you for testing it out! I can save the effort now for getting a VPN.

@evilknivel @fastriker @zindy
When you all search in your regions what 433 MHz products do appear with reasonable prices, if any?
I'm considering ordering a few varieties to see if they use identical chips.
Even if the housing style is different if I'm lucky it might have similar components.
from reedtripradio.
@mightymos good point in have at least one cheap 433mhz door Sensor laying around and will look to it today an come back to you
from reedtripradio.
@mightymos Good idea and thank you for your efforts!
These round ones seems to be pretty cheap. But they are running on a CR2023 and therefore might be not the best choice though.
These ones are also not to expensive, but have the same problem.
These ones have very uncommon batteries.
These ones are running on 2 AAA and are super cheap, but not that common.
I can also order some and take a look inside.
from reedtripradio.
For the Last one i can tell you that they dont even have a rf Module. They just alarm wenn you Open a window.
from reedtripradio.
@evilknivel Thank you! They advertise it with "Wireless Frequency: 433 MHZ Transmission Distance: About 120m without barrier" :/
from reedtripradio.
@fastriker Sorry mate, VPN won't help: If I change the shipping country from Belgium to Germany, I get a "Page Not Found", so it looks like the seller won't deliver to Germany for some reason.
May be related: I've seen discussions on the aliexpress subreddit where several EU countries with plastic packaging bans (austria for example) will only allow import if there is a local company that will handle the packaging waste, then freight forward the plastic-stripped item to the end user. If the country doesn't have a freight forwarder, all the items disappear from ali.
from reedtripradio.
Don't think the plastic bags are the reason. I do get stuff in plastic bags from Ali here in Germany. My guess it is the VAT which the seller has to handle now.

@fastriker
Thank you for the list, I guess we will find out...
My concern is that many list the 1527 format.
This could just be protocol choice as discussed below OR maybe they are using a particular chip EV1527.
In that case I guess there might be no separate microcontroller to reflash :
http://www.sc-tech.cn/en/EV1527.pdf
from reedtripradio.
@mightymos Thank you! The fact that they are running with another voltage level 3V/12V already suggest, that the hardware is different. Of course it could have the same chip in the end, but it is not just another housing - unfortunately.
I saw a German article about the regulations @frollard mentioned. I do not know it, but eventually it is the reason for the geoblocking.
from reedtripradio.
@fastriker The package litter problem is only hitting Austria. The other Sellers not delivering to some Country's is caused by VAT the seller has to do for the target country.
Some Sellers just want not to do, so the can't offer for this country's.
from reedtripradio.
@frollard @zindy @fastriker @evilknivel @Jason2866
Unfortunately bad news, I ordered a variety of sensors and none use the STC MCUs as best I can tell.
Many have soic (8 pin) without markings but measured voltage supply pins do not match expected STC pinout.
One promising board actually had pads for programming, but no datasheet was found (fmd j2n1gkh microcontroller [freemont micro devices]).
Additionally it appeared to be an I2C, IIC, or SPI interface (maybe it was three pins?) so perhaps more cumbersome and would require external programming hardware.
However, I recommend looking at the current price list in the readme if interested.
from reedtripradio.
Wow, thank you for your thorough investigation! I see on your project page that compatible widgets can be purchased on amazon.de (although at twice the original price), that will be good news for @fastriker and @evilknivel
Take care mate!
from reedtripradio.
very nice that we now have an other way to get the devices. Thank you
from reedtripradio.
Thank you very much @mightymos for your invest in time and money for the research!
I will make an order on amazon for testing and hope for cheaper options in the future to equip the whole flat :)
from reedtripradio.
Now listing compatible sensors in readme
