How do I add the soil-moisture sensor to domoticz?

Yes, @epierre should clarify what sensors used and how it should be connected in the sketch.

If a new sensors type is used we should probably keep the old example and create a new one for this.

Maybe a bit late. But the soil moisture sketch was the first one I brought into production by soldering it on a PCB. I added it to Domoticz as a motion sensor, not as a switch. And it's working great. If the motion sensor is telling that there's motion, it means the plants aren't thirsty. If there's no motion than the plants need some water. I even let Domoticz send a message to my mobile phone when the plants are thirsty ;-). I keep forgetting to give my plants water on a regular basis, so this sensor is really helpful.

Hi @TheoL
Motion sensor and Switch (and also the soil moisture sensor) work the same way in Domoticz. Its either 1 (ON/Motion/Wet) or 0 (Off/No motion/dry).

Well it is here in the sketch: " Required to interface the sensor: 2 * 4.7kOhm + 2 * 1N414"

but it was better in the post: http://forum.mysensors.org/topic/514/soil-humidity-and-temperature-sensor-watermark-davis-granular-matrix-sensor/2

and yes it works with two connectors this way !

@hek I'm not in the list ;-) https://github.com/mysensors/Arduino/graphs/contributors

I can see you in the list :)

visibly I searched myself at the bottom, but I had many bugs as it seems ;-)

So this works with the sensor I linked above (= the one in the picture above)? I though changing the voltage way would destroy the sensor..
My goal is to have the sensor in soil for years though. Even if I turn it off while not measuring it might break I guess.

Anyone? Because I really want to use the sensor but I don't really get the posts her ;)

And this sketch is supposed to be connected as this? :)

Not quite. There are no diodes and no resistors in the solution I use.
