I ran into this nice review
1 did anyone try this? It looks promising (I like the concept of using a shortcut by waterdroppels…)
2 I don’t think if it would connect to homey via the Tuya cloud or zigbee app (it’s not listed), does zigbee standard support devices like this? Probably not?
Might be nice for the “hot Oder schrot” 
@Undertaker
Feature that seems to be missing on this one is a heater for the print (so droplets evaporate faster)
It looks nice, but my experience with these types of bare-copper rain sensors is that eventually (often within a couple of months) they will corrode and stop working properly. Plus that a lot of cheap solar-based devices often use cheap epoxy that starts cracking due to thermal expansion/contraction which will lead to water ingress.
And no, Homey will not support this out of the box.
I bought this rain sensor recently. I works really well in the Smart Life app, but it’s not supported in Homey (yet). If you add it as Zigbee device, it shows up as unsupported and you can’t use its features. And the Tuya Cloud app does not recognize rain sensors, so that won’t work either. Such a shame… 
Actually, scratch that–
Using the Test version of Tuya Zigbee, I was able to bind this sensor to Homey. Seems to work perfectly.
How is this sensor now you’ve had it a while? Does it stay connected or drop off the network?
Thanks
Hello, where i find “test version” of tuya Zigbee?
Yep, thx a lot 
Works like a charm, had no issues with it so far!
Or, you just click the test button to switch from the live version’s app page to the test version’s 
.
Yeah i have had one installed for a while now and works perfect. Far better than home made ones I’ve had a go at with water leak sensors.
At the minute i have it setup to notify me when the water alarm turns on and works great but does get triggered in the morning from dew.
Have you managed to setup from actual rainfall intensity and water values to trigger rain at?
Tested for about 3 weeks now and fully functional. I am very surprised! Fantastic sensor for 15 euros..Great!
Thanks for sharing your experiences with this device. Based on this thread and the relatively low cost, I’ve decided to get one myself as well. Using the test version of the Tuya Zigbee app I was able to connect it without the need of a Tuya ZigBee Gateway.
Based on some quick tests I found it detecting water really fast, but just like @J273 mine triggers in the morning from dew as well, but for my use-case that is no problem at all.
My goal is to use it as a corrective mechanism to control the smart garden awning when rain is detected, together with different Netatmo modules. The latter unfortunately isn’t able to trigger upon the first rain drops. As a preventive mechanism I’m already using the forecast from the Dutch KNMI weather app.
Ich habe die Tuya Zigbee App auf Test gestellt und den Sensor als “rain sensor” eingebunden, allerdings wird er nur als Schalter dargestellt. Wir wird der Sensor in der Tuya Zigbee app Test richtig erkannt?
The device is likely a newer HW revision that’s not supported by the Tuya Zigbee app. The developer is no longer active, so it will likely never be supported. As an alternative, you can buy a Tuya ZigBee or MultiMode gateway and link it with the official Tuya app:
