Yes. I wonder how accurate that would be. It would be a good experiment to have them side by side and compare the values.
Edit: reading the post now, I do not see an example of the quantity of rain. Only the intensity
Used the wrong word, indeed intensity but this might give an idea about the quantity.
That is interesting. I just placed an order on Aliexpress before knowing of this rain 2in1 sensor.
Hello,
This zigbee sensor normally detects water leak. If raining, heavy or little rain, it should trigger info. On top of, being AAA-Battery powered and less expensive, it should keep charge on a longer period than button cell based units.
You could also locate the main unit inside the rain collector box and the water detector contact, thanks to its contact cable, inside the collector …

Thanks Parrel for this great idea and the perfect instructions.
I used a wired Shelly Plus 1 + Shelly Plus addon for this. I didn’t want to use a battery as it can get very cold here in winter. I have no experience with ESP and Shellys are very easy to integrate with Home Assistant.
To mount the rain gauge, I ordered a “Misol mounting arm” from AliExpress.
I let 1740 ml drip into the rain gauge over 4 hours and measured 1100 flips.
1740 ml / 1100 flips = 1.5818181818 ml/flip
I measured the area of the rain gauge as 5470 mm².
5.47 ml = 1 mm of precipitation
5.47 ml / 1.5818181818 flips = 0.28918065 ml/flip
Now it just has to rain.
