Yes, selling boards (none commercially) is ok.

That's hard to say as it is up to the plug in developers and I'd guess if that device could become popular

@mfalkvidd Thank you ! that did the trick. John

As I recall the "normal" bootloader have not configured the WDT (I guess it's too difficult for a newbire to understand and handle WDT) Optiboot have WDT configured and you can set it Remember to call this at for each less than 8sec, else you will get reboot via watchdog I recommend not to set the wdt time too short, as you then won't be able to upload a sketch, as the Arduino then will reset during sketch-upload (But this isn't a problem when using ISP) wdt_enable(WDTO_8S); https://github.com/Optiboot/optiboot/wiki/HowOptibootWorks

@korttoma Thanks, somehow I was under the impression that the MySensors GitHub devices were all I had to choose from. Your answer make me realize I could use any (most) of the Vera Std sensors. John

@Nca78 Thank you so much for your incite. John

For those who read this post: Since my original post I found the wait(time) command is a MySensors macro that essentially is a "wait millis()" function.

@gohan, Thanks for reading and your response. Since posting I've continued to learn and have found the MYSController program which answers my question regarding the convenience to adding sensors to the gateway.

@johnrob I understand wanting to apply the calibration data even though you don't need it. I did the same. The Arduino hardware doesn't support 32 bit calculations, but it can be done in software; it just makes your code bigger.

@johnrob exactly. All MySensors defines are designed that way.

Hello Use the include procedure on the MYSensors Plugin Icon under settings you will see start and stop if all is working properly just press the start button you will see a dialog that tells you to activate the sensor you wish to add. If all goes correctly you will see a node added as well as the sensor. Now that is how it use to work with earlier Libraries if you are using 2.2 library I will presume it will work the same way.

It works the same as a node, just don't use delay and sleep in code but use only wait() at the end of loop if you don't want to flood the controller

Thanks to both The reason I asked was some time back I was playing with a RasPi board and found the micro-usb to be very unreliable. JohnRob

Hello, no there is no minimum frequency but for a serial gateway I would keep it at 16MHz to avoid any missed messages. It also allows a high baud rate on the serial connection. For battery powered nodes I use them mostly at 1MHz, there's not much interest going lower as you get no more gain in allowed voltage and not any significant gain in power consumption while the processing time increases.

As far as I know all the radio pins have some kind of "default" pin assignment and only in special cases you need to reassign them. Also depending on the processor type or board type you choose in the tool the default pin assignment may differ. I think it in case of RFM69 is handled in the RFM69_old.h (someone with better knowledge please correct me if I am wrong).

Thanks to all for your help. I think I have enough information to start my gateway (as soon as the hardware arrives). My first step will be to add a potentiometer to the gateway as a test input before tackling a sensor node. John

@johnrob What I meant was, wired nodes will most likely use an ethernet or RS485 gateway, if you wanted to go wireless with your nodes, you could use the serial gateway with an nRF24L01+ (which is what I am using) or an RFM69 or similar. There is also the ESP8266 route. So depending on how you want to connect your sensors to Vera will determine what gateway you will need. The MySensors site has a page on how to select a gateway. https://www.mysensors.org/build/select_gateway
