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?

Any ETA on support for RFM69 ? Need to extend my coverage

Do you have an example sketch of connecting two PIRs to one Arduino? Would really need that in my setup.

@mfalkvidd Alright The thing is that I have my Raspberry Pi as a Gateway today near my server rack and would like to measure the temperatur. Maybe I just get a Nano to do the work for me. Just would have been great to use the Raspberry.

Can I attach one or more DallasTemp sensors on the Raspberry Pi gateway?

oh, I should have read this before I ordered the TCRT5000. I two seems to have hard time to get readings from my water meter.

I also have this small wheels.

I have a RPi and USB camera, so I could try that solution. But should have been nice with the TCRT5000.
Have anyone made any updates?

Should have said that I was trying to run it on a Node MCU 0.9. I can compile fine for Arduino Nano but not for Node MCU. Also I got another error now when I upgraded to 1.6.12.

Running 1.6.11, will try and update.

I use the following code, I have added the GW support for ESP board.
