General Discussion

Thank you all for your comments! We ended up discarding the acer and bought an asus gaming laptop at a similar price. So far my son is very satisfied.

@Lars65 Take a look here https://forum.mysensors.org/topic/1607/safe-in-wall-ac-to-dc-transformers

yes, trank you. I now know

@scalz - jeez I spent a lot of time invesstigating this :-)

I used a cheap ebay infrared door minder in my parking sensor it seems to work very well for the price.

I can only give you my personal advice. Since you're on this forum, I expect that you are interested in sensors and stuff. In that case. Download this library and look at the examples. Try to understand them and try to adjust them slightly. But, maybe it is a better idea to google "c++ tutorial". Arduino is C++ based. And this will definitely teach you the basics of the language. Last, try to look at the Arduino website.

@chuckconnors We moved a lot of examples to a separate repository on GH during our release, as we can't have all the 3rd party libraries distributed with the core.. This is located at https://github.com/mysensors/MySensorsArduinoExamples, where you can find lot's of examples (all of them is updated to 2.0.0)

@tbowmo Thanks for the reply. I'm still a newbie with all this. I think that I have 2.0 installed but most of the code examples I see or have used in the past are not 2.0 . Can you tell me how to install the older library and get rid of the newer one? Basically I'd just like to be able to upload the code I've used before to the new nodes.

Right now it's arduino based. We are thinking about possibilities to separate us from that build environment, because it's so weird.. The only problem is that arduino is so popular with newcomers to programming and hardware, and for them it's relatively easy to use. It's only the more seasoned developers that knows something better is out there, that complains :) I still use the arduino environment for the basic sketches, as it kind of works, and atom for core hacking. I've got a set of bash scripts to help me along, and use gdb for debugging in target (samd hw) I think there are some platform.io integrations as well, but haven't had the time to look into that. We want to reach out to as many as possible, and that's with arduino at the moment.

Yes you can have as many as your controller supports. If you have nrf/rfm radios on your gateways they need to be on different channels (but it sounds like you'll only be using local sensors so this might not apply to your setup). I don't know if Domoticz has a limit on the number of ethernet gateways but I think you can add as many as you want to.

The serial API (glue between gateway/controller) is documented here: https://www.mysensors.org/download/serial_api_20 You can see the messages sent at boot in the serial console. It's just sends the presentation and controller usually transmits unit configuration back to node. (Unless node requires an id which takes place prior to this.) Suggest you have a look at the (somewhat outdated) sample controller to get started https://github.com/mysensors/MySensorsSampleController

@nemik said: My advice would be to visit Alibaba and try to find someone who sells the product most similar to what you want. Then reach out to them about modifying it and branding it for you. Some sell iBeacons and such in wristbands already, so it might not be too big of a stretch for them to customize it with some other electronics that you might have in mind. Good luck! Thanks!

@cablesky said: Hi, Can i use the Relay-Sketch with the Sleep-Function? I would like check every 5 Minutes, if the switch for the relay is changed. If the switch is changed, then the relay switch. I use mysensors with FHEM. Anybody know that? Hm. Very interesting. Can you clarify a little what its purpose is. Thanks :)

@Fat-Fly check the "range issues" troubleshooting flowchart at https://forum.mysensors.org/topic/666/debug-faq-and-how-ask-for-help

@moskovskiy82 could you describe why you want the average? Are you sure the median wouldn't be a better choice? Or letting the controller handle averaging, since it will have access to past events even if the sensor is restarted.

I found it, i made my project.. now i only wanna put a LCD display with some statistics..in future.

Short answer: No. Slightly longer answer: If you are sleeping to conserve battery you would need to power down the radio, so even if MySensors supported interrupts there would never be an interrupt because the radio would be sleeping as well. The power requirements for the radio in receive mode are too high for battery use. Long answer: Read the following earlier threads on the same topic: https://forum.mysensors.org/topic/2852/arduino-sleep-wake-on-interrupt https://forum.mysensors.org/topic/676/interrupt-on-recieve-radio-data/ https://forum.mysensors.org/topic/1461/how-to-sleep-the-arduino-but-still-have-it-respond-to-the-vera https://forum.mysensors.org/topic/1250/wake-up-over-radio/ https://forum.mysensors.org/topic/3100/low-power-servo-actuator/

@y4CdW42Ol8 Have a look at the examples as supplied with the mySensors library. Both ways are implemented extensively. The gw.sleep(...) function will be the way to go for the 12 hrs. you'd like to put the sensor asleep. This is used in many examples For waking up with interrupt have a look at the example for the power meter. It wakes up the sensor when an interrupt occurs. Be my guest to find your own way of programming this, but as @mfalkvidd already pointed out: MySensors has its own functions! Good luck, Boozz.
