I have now solved this problem with Fahrenheit instead of Celcius.

I had to change to this --->
float temperature = static_cast<float>(static_cast<int>((dallasTemp.getTempCByIndex(i)) * 10.)) / 10.;

From this --->
float temperature = static_cast<float>(static_cast<int>((gw.getConfig().isMetric ? dallasTemp.getTempC(dallasAddresses[i]) : dallasTemp.getTempF(dallasAddresses[i])) * 10.)) / 10.;

Now it gives me celcius.
Thanks for nice example.

Thanks for a nice project.
I am trying this but I always get Fahrenheit temperatuers in Domoticz.
I have change this line in the code.

From
boolean metric = false;

To
boolean metric = true;

Something else I should do?

Ok. When used a flashlight it response with a new lux? value.

I was thinking of using this sensor on the laundrymachine.
My machine has a led that is blinking when the laundry is ready. Can I use this or should i use the power meter puls led sketch instead?

Thank you for the help, and thank you for an intresting project.

No, there is nothing else except the zeroes.
Bad light sensor mabye?

This is what I get in serial monitor from the light sensor.
I dont know what to look for.

sensor started, id 1
send: 1-1-0-0 s=255,c=0,t=17,pt=0,l=3,st=ok:1.4
send: 1-1-0-0 s=255,c=3,t=6,pt=1,l=1,st=ok:0
read: 0-0-1 s=255,c=3,t=6,pt=0,l=2:M
send: 1-1-0-0 s=255,c=3,t=11,pt=0,l=12,st=ok:Light Sensor
send: 1-1-0-0 s=255,c=3,t=12,pt=0,l=3,st=ok:1.0
send: 1-1-0-0 s=0,c=0,t=16,pt=0,l=3,st=ok:1.4

The sensors are powered from a usb phone charger 2,1A so it cant be a power problem.

I have installed all the 1.4 files in my Vera lite.
Made an arduino nano serial gateway an it seems to be working. plugin version 1.4 - Lib version 1.4 It says.
Made one water meter sensor and one Light sensor.

Both is included and everythis is ok but I dont get any sensor data.
If I restart the sensors i get a new time for last update, but after that it dont update again. No data and no more last update.

What am I missing?
