Rain Detection (real time)

[pepe6859 0]

I have a very nice and reliable configuration to close main water valve to my irrigation system based on Wundergroud "rain prediction". Now I would like (wife request) to close about 5 windows shutters as soon the first drop of water coming down from sky above appears.

Can't find any Z-wave ready or at least something that immediately close a dry contact based on water drops detection.

Any suggestion? In the name of very clean windows....

use a fibaro water detector,

2 wires in you're roof gutter should do the trick

[rtripa 1]

You can make one, plenty of instructions on the web, otherwise see here:

I don't own one of these, but I'm considering.

Thank you akatar but water detector will not be fast enough.

rtripa, I found a dealer in Spain for the Hydreon Optical Rain Sensor - Model RG-1. Will call them tomorrow to see if they have it in stock.. It is exactly what I was looking for!!!! Thanks!!!

You also have the Kemo M152 12V Rain Detector Sensor Relay Module

it works very well

Looks good and comes with space heater as well!!! Thanks.

Nice one, didn't knew this version.

I did this with a non-zwave rain sensor.. it just gives you five volts when a rain drop hits it, which you detect with the RGBW controller

found it on alibaba, about $2 each but there was a minimum order quantity (10 I think)

Just keep in mind such sensors need maintenance, otherwise they will fail. Tried it and it was too unreliable. Maybe the optical system is better. But what happens if it gets dirty?

[Krikroff 199]

dawiinci, you are right

-> The advantage with the Kemo M152 is its integrated heating system but it is certain that you will clean the sensor one or twice a year

How can you control the output?

Using a Fibaro RGBW sensor?

Thanks

Kemo M152 gives output as ON/OFF signal, and won't give you amount of rain value, but just information if water had contact with rain sensor or not. So you need to use Fibaro Universal Sensor FGBS321 for Kemo M152

RGBW module works as analog 0-10V input.

I'm also building device using fibaro FGBS321 and Kemo rain sensor + soil humidity sensor. I'll try to put it all together next weekend if i'll have some more time. I'll let you know when it's ready

Nice project. hope it will work

Would you mind to share what kind of actuator you are using to close your windows?

i use fakro zwave window openers

I hope you share the schematics and the results

It took me a bit more than "next week" to finish my project, but i finaly did find time to do it. 

 

I used:

- fibaro Universal Binary Sensor

- Kemo M173 soil humidity sensor

Please login or register to see this link.

- heated rain / snow sensor

Please login or register to see this link.

- meanwell 12V DC power supply

- splashproof housing

 

Soil sensor checks every 30min or so (it's built into the sensor itself) if the soil is humid enough or not (you can control sensivity) and than sends status to fibaro.

Rain sensor sends status to HC2 as soon as first drop of water makes contact with it and activates heater integratet into the sensor.

Than you can do with this info whatever you want.

Oh, and only thing that is not working yet, is dallas temperature sensor connected to UBS. I tried 2 diferent and it doesn not show up in HC2 when adding UBS. I don't know if it's firmware glitch or i conected it wrong.

How you have realized (in HC2) lock watering when the soil is wet or raining?

Hi smk23us,

 

unfortunately, the links in your post don't work any longer - Can you pls re-post? Thanks!

 

Cheers
