Since it's not wireless, how do you envision this being used?

@NeverDie - You could att it to a https://www.openhardware.io/view/4/EasyNewbie-PCB-for-MySensors and get all the benefits from both. I like that it includes ATSHA204A.

First version of this board does not contain mistakes and works properly. I will remove "work in progress" mark after some tests soon.

@Koresh very nice. Do you plan to sell these assembled? If so, is there an estimated price point?

@scurb This looks very interesting and my factor now to save me from having to create my own :-). I have been planning to do the same thing (although maybe on a smaller software scale) by writing a simple Python server that would pull serial packets off of a gateway arduino (either running mysensors or something I write myself) and pipe this through MQTT to openHAB. I have two questions: How do you interface with a sensor network? Do you go through a serial connection to read the serial packet format (a,b,c,d)? I see several implementations that put the mqtt client directly on the Arduino, but it seems much cheaper for me to just plug it into a USB port to get a virtual serial port instead of investing in a separate ethernet shield How does an item configurations look like for a switch in openHAB? I'm looking to build a toggle switch which toggles light on or off every time it is activated, and I cannot really understand how to configure the switch to allow this behaviour for an mqtt input. Feel free to take the second question with me directly since this might not be very interesting to the others in the forum

@yoonie said: For the pro mini version, should i create another Openhardware project, or should i put it here, in the already existing project? Might be better to create a new project as they uses a different set of design files.

@Sunseeker According to the Connecting the Radio page, D2 is the default pin for the CE signal for the NRF24. If you'd like to use this pin for I2C, you can free it up by assigning a different pin for the CE signal by adding this line to your sketch: #define MY_RF24_CE_PIN pin IIRC, all available pins should work for this purpose (D0, D3, D4). Just pick one and if it doesn't work, use one of the other pins. Please make sure to add that line before #include <MySensors.h>.

@GLAB You can set the frequencies using the settings in MyConfig.h, which is in the MySensors folder. If you put any of the defines from MyConfig.h into your sketch, they will override the MyConfig.h setting for that sketch only. If you are using the RF24 radio, there are different channels which correspond to a given frequency. The default is channel 76. There is a list of typical channels in MyConfig.h. If you want to change the channel for all the sketches, change it in MyConfig.h. If you want to change it just for the sketch, add a define to the sketch. For example: #define MY_RF24_CHANNEL (84) The problem with changing the channel in a sketch is that the gateway has to be on the same channel to receive from the node. So, normally it makes sense to change in MyConfig.h because you usually want the gateway and all the nodes on the same channel. Other radio's like the RFM69 list the frequency instead of using a channel. They can be overridden in the sketch as well. You can find the defines that are needed in MyConfig.h

Hello, i'm making some progress; received the components this week. Unfortunately it doesn't work... yet For now i have SanityCheck failure in to logs. I'm afraid my soldering of all these little components is not good. I tested with a multimeter the 4 pins and i have continuity on one of them but maybe not the others so i guess i will have to try remelting all these small regulators ???

When you read the data sheet correctly you can see, that the distance between the pins is different for a AA and AAA battery holder. That`s why I was asking if somebody can recommend a holder that fits.
