Domoticz

I want to build a soil moisture sensos transmitter basically as done as in this threadviewtopic.php?f=31&t=325#p7783 but instead of giving me the temperature, i'll need to know when to water my flowers. I am using Arduino one and the same transmitter.

1: Is it possible to reviece the transmitter signals directly in domoticz using rfxcom or do i need the same type of reciever?
2: Does anyone have a sketch to do so for testing?

I don't know if this can be done using the 433mhz transmitter, but I know you can do this using mysensors.org.

The idea with mysensors is that you have a arduino running mysensors gateway, connected via usb or lan to the raspberry pi running domoticz. Domoticz sees it as a hardware device.

You then use nodes (arduino with a connected sensor like your moisture sensor) to send the data to the gateway, the gateway will send the data to domoticz, and under devices your mousture sensor will show up.

The mysensors library already had a ton of sketches to use. The only thing is that you need a second arduino to work as gateway and a rf transmitter for earch arduino (NRF24L01+)

Give it a try, once you understand the concept it is very easy to add all kinds of sensors to domoticz.

I'm running domoticz on a windows server - basically because i have problems understanding programming. Been surfing on mysensors but as i don't know programming i assume i have a problem...

That is the beauty of mysensors, there are already a ton of sketches you only have to upload to our arduino, so no programming is required unless you want to extend the functionality.

This sensor is supported by the RFXtrx433 and RFXtrx433E:

@Panda: Cool! I'll have another look
@b_Weijenberg: Awesome! That's exactly what i've been looking for

Note that the XT300 sensor has only 3 channels! So you can only use 3 at maximum.

What protocol does the xt300 use?

I am currently testing on Arduino with a SYN115 (433mhz) transmitter
I have a succesfull reading in Domoticz on my RPi with RFXCOM by using the KlikAanKlikUit (X10) protocol which simply toggles a switch ON and OFF.

However i intended to use my Arduino with multiple sensors (temp, hum, baro, lux, etc.) and i want to send over the sensor readings to Domoticz to display and use the values in scripts as well. So i require to send data instead of the above ON / OFF command.
I've successfully tested Fuzzilogic and my arduino now appears as "Cresta" device in domotics.
