Sorry, I'm a bit slow and maybe a little off-topic: A quicky:
Can I read somewhere how payment is done when ordering from openhardware.io? On the start page for openhardware.io there is no clue. I've also tried to search this section (easy-newbie-pcb-for-mysensors) for "payment".
Yes, I've read that the "order" is more like a forward of orderinformation to the supplier, but do I really need to order first and after that ask what payment solution is present?
@sundberg84 Thanks a lot for taking time to answer me. I will study all of your links carefully! Tks again!
EDIT: Wow! There is a lot to read, learn and do! ..and I guess I should unplug ALL of my nodes..

Posted in General discussions where we can talk about "everything".. Right?
I'm in the beginning of my learningcurve but I built my first 4 mysensor nodes and there will sure be a lot more. Very briefly; my enviroment; raspberry pi with domoticz and 5 "zwave plus" units and a serial GW to MySensors and 4 nodes (motion, button, relays). It's overwhelming and exciting. Lego for adults.
But.
My first step: Euphoria, when understanding that everything is possible.
Second step: Shopaholic! I bought a lot of different arduinos, radios, component and sensors. (btw; isn't it unbelievable that you can order stuff for 1 euro sent with free shipping from china to northern europe. I still don't understand it!?)
Third step: powersupply? casing? radiorange? mounting details? stability?
Now I start to think a little about safety – I don't want to burn down my house – and security:
Safety: How do I make my nodes as safe as possible (in an electrical sense)? My first nodes was powered by cheap asian-made USB-chargers, but how many didn't serve less than 5V? ..marked with 1A or 2A but giving me 0,5A (lack of quality, but cheap of course). Can I trust them or have anyone had some incident (like fire, short circuits, overheating) with these kind of cheap low-end products? Anyone who can share thoughts about WHAT to think about or even better; building hints/tips? (Yes, I ordered my first pack of power supply modules; http://www.ebay.com/itm/261985573055 )
Security: Thoughts in two directions;
a] Building guidelines for parts of the system that includes physical security, larm sensors, motion detectors, door sensors that are vital. Yes, I understand that ANY radiobased network could be taken down by radiojammers.. What approach should I have? "cabled hubs" (mySensors ethernet gw?) by wire controls/reads sensors. Maybe having a cabled ethernet as "back-bone" wiyh 3-4 gw/repeaternodes? Anyone who have smart ideas or building concepts? Maybe build a cabled ethernet backbone, but this wireless stuff feels som comfy..
b] I've read some posts about signing (e.g. https://www.mysensors.org/about/signing ). Does this extra complexity affect the stability/reliability? ..and whats next step? encrypted messages? certificates?
Share your thoughts..... ..if You want to..
Best regards from a true Newbie!
Lovely. Will be this evenings experiment – if I got the right PIRs.. – to find out...
Thanks for answering!

Thanks again. Important aspect, of course!
I'm new to this so I don't have any own oppionion about how reliable the communication is. So I really appreciate your input!!
Hi Yveaux!
Thanks for taking your time and answer me. That's of course a smart approach and maybe the normal way to do it.
But for the moment (and for learning purpose) I want the logic in the sensor. But I got an idea from Your approach. Maybe I could let my MyS-node present a "dummy-relay" (S_DOOR) which the controller could set on & off depending on sunrise/sunset. (I have more than one relay on my MyS-node, so some logic must be there.. And also a "override"-button which manually disable the MyS-node/relays.)
Like: Controller: "After sunset"-event: set "dummy node=on", and then att sunrise "dummy node=off" and use "savestate" or something locally on arduino to save this "state", which then the controller checks if the sensor is enabled or disabled.
Is that possible?
I'm open for more ideas and technics..
/Per
[My enviroment: controller: domoticz on Raspberry PI/zwave/Mysensors)
My first motion/PIR node with 2 relays now working. Some other nodes also running. But I want to add one feature; "disable daytime". What is the smartest approach?
(I want to block the logic daytime)
Of course very happy if someone willing to help a rookie on it's very first shaky steps..
Thanks
Pelle
PS! Read this post (https://forum.mysensors.org/topic/2116/hard-to-grab-time-and-value-sent-from-controller) about grab time.. Also read this one about variables (https://forum.mysensors.org/topic/3326/requesting-variables-reliably-how). Light sensor is my last option; I've read this one; (https://www.mysensors.org/build/light-bh1750)DS
I'm still in the beginning of my learningcurve and my code is not the cleanest. And my wiring and coding for the relays is probably the most strange coding You've ever seen..
The page "https://www.mysensors.org/download/serial_api_20" – which i guess is a well visited page – needs a css-adjustment, at least in firefox, to display comments below with the right left margin:
Maybe:

Hi!
Thanks for Your troubleshooting guide. For a newbie (like me) it's really appreciated!
A newbie question: Why do You use a 4.7 µF capasitor and on the page for connecting the radio (https://www.mysensors.org/build/connect_radio) they use a 47µF capasitor (10 times bigger)?
