Water leakage sensor for RFXtrx433E

[niclasc]

I'm looking for at water leakage sensor that works with my RFXtrx433E

I'd like to have it behind my dishwasher

Is there a sensor for that?

What kind of looking have you done?

Why so rude?

I dont want to build a sensor. I was hoping to find one to just buy and connect to Domoticz

[b_weijenberg]

The 433.92MHz version of this sensor is supported by the RFXtrx433(E)
http://www.visonic.com/Products/Wireles ... or-mct-550

Maybe this one can be used as Lighting4 device.
The oscillator resistor must be configured to 3M3

Note that this sensor does not transmit an alive signal or battery empty!

Was I rude? If so then I'm sorry. On the other hand you said that you were looking. So looking to buy, build or just find? I suppose that you need info about those devices and that is what I tried to offer. Obviously my mistake, but now you have found.

Hi. I got one of these to try. Can you explain what you mean by "configured to 3M3 please"?

[b_weijenberg]

You can configure the oscillator with a 1.5M, 3.3M or 4.7M.
Select 3.3M

Sorry to be so stupid, but how do I configure it please?

Bought two of these, see if i can get them to work.

Any luck with getting these working?. Looking for a simple sensor i can put under my bath.

Ok thanks, if you could keep me updated as im interested in installing a couple of these in my property.

[gertlind1]

Received the stuff today.
Looks good for the price.

Have done some testing.
Enabled the Lightning4 protocol.
Added the battery and dipped the water sensing part in a glass of water, no cigarr.

Made the changes suggested by b_weijenberg a few posts up.
Now i can get it in as Lightning4 switch

However, the switch in Domoticz stays always on (lit) and can't turn it off.
When i dip it water i can see in the logs that it transmits.

Code: Select all

How do i see what kind of message it sends so i can make a LUA script taking care off the alarms.
Or, maybe it should be added as some other kind if switch??

[b_weijenberg]

This type of sensor transmit only the ON packet if the sensor is triggered. The state must be changed to OFF by software. Set the state back to OFF after a delay of a few seconds.

[gertlind1]

Ok, got it to work.

Created a dummy switch that the sensor switch can turn on.
I hided the sensor switch with the $ sign.

A lua turns on the dummy switch the a leakage is detected and sens an Prowl message.

Code: Select all

if (devicechanged['$Vattenlarm']) then
    print "VattenLarm AKUT"
    commandArray['Läcka Kök']='On'
end

Works as a charm.

Well worth the money.

Thanks for bringing this up in the first place

Hello dear experts,
Sorry to bother you in this old post but I couldn't find solutions in other topics (I am a just starting newby).
I have the very same problem as markk (03 feb 2016); configuring the oscillator I take it means remove the solder connection of 4.7M and solder a bridge to 3.3M, I made a dummy switch, but I cannot find the complete code to send a message and set the state of the sensor to OFF?
Please can anybody direct me to solve this issue?
Thanks a lot (and forgive me my lousy English)

Hi all,

I also bought the waterflood sensor:

I think this version is already fixed for 433. Does anybody know which battery this devices needs?
