I have an air refresher in the main bathroom, the problem with that one is that is spraying in constant intervals, so even if no one has been in the bathroom for a long time (during night for example).
Now when I have started with Arduino and MySensors I think it would be possible to hack this one, so I can trigger it via sensors or schedules.
Have anyone tried this before? 
Great! Thanks for the help
Now I just need to figure out a good placement for it and get values to Domoticz.
But this helped me a lot to get started.
Thanks!
Yes I ordered a couple of days ago, waiting for them Need them for the temp. sensor as well.
Again, thanks for quick reply.
I´m starting to get a better understanding now of how its meant to be used 
I have ordered some hardware now and will start to test.
Thanks once again.
Is there any updated sketch to use with the Soil Moisture Sensor shown in the pictures?
