    OK, this worked and I am encouraged! I haven't figured out how to get the status LED's to work yet though, since they just stay on (after enabling it in the config H file). Unless I missed it though, I do not know what the fields are that are output via serial. If I do not find the info, I guess I could just reverse-engineer the software to figure out how to send simple data back and forth from each unit. Pretty cool library! Heavy though, but not as heavy as expected. I still have room for my RGB LED effects processing. Now I just need to see if my interrupt handling using timer1 is going to hose this library. Any thoughts?

    @martinhjelmare: yep, I like the vid too. it's funny to see all these new materials. :) you are right, I will use parts of rollershutternode I think, for the ac powered version. for the batt powered, I will use my "camel" sensor board plus others thing of others boards I made. I totally agree with you. When I do something I try to keep things reusable. As I am originally software dev, I always think factorizing, libs like a toolbox...lol. But I think electronician do the same.

If you are in Rome I can hand it over directly . If you are at EU maker faire this week end even better see you there. Otherwise I ship them too KR Still got the 10Kits? You can still buy these kits from my homepage.

    Finally found the repo for what i think is the raspberry pi MQTT Gateway... Link, I'm assuming the file i need to be looking at is the MyGatewayTransportMQTTClient.cpp. However, there is no MakeFile there, am i being stupid or blind, how would i compile this gateway file to then be able to run it?

    @epierre said: @alexsh1 said: Depends on your sensor. you do not have to add anything. yes and no, you don't have a datasheet for the board... 10K is 10K so you know it ;-) Actually, I have the datasheet for my board and this is adjustable resistor :) Anyway, I got mine working without any additional 10k resistors. I hope it helps.

    @Sparkman You are right. The pin names on the sensebender, corresponds to the pin names on the arduinos, so the interrupt on D3 is the same as on the arduino.

    @siklosi thanks, so that means this module would be only good for serial monitor? Is it possible to do serial monitoring with mysbootloader / myscontroller? I am currently using serial gw with vera - if I am to use myscontroller do I have to disconnect it from vera and connect it with computer running myscontroller?

    I had the same problem a few months ago. The problem solved powering the arduino from a different power supply. You can read a bout it here Node freezing up No more problems since

    Thanks a lot @AWI for the suggestions and explaination, even if it's a little difficult for me to understand. I have to take some other for other LED strips. So I'll take IRLZ34N or BUZ71 instead my BUZ91A so they didn't get so much hot. :-) Simon

    Ok, finally I found the Problem. I changed the prescaler value of Timer0 becuase I needed a higher PWM Frequenciy. Unfortuneatly this also affects the millis() function that is used in gw.wait. It turns out taht with the changed TImer 0 Prescaler 1ms was not 1ms anymore but less. So the gw.wait(750) where only 750ms/64 which is not enough for DS18S20 conversion to take place.
