Thank you. I now have two sensors/radios each reporting separately to the Gateway without any problems. Plenty more to come. As you said, "I didn't need to worry about it"

@mfalkvidd OK so what is the default channel. Is it decided by the Gateway, how is it set? And how would I need to know if I need to change it? Is it set in sensor sketch?

@AWI Thanks for that. Do I have to specify a different MY_RF24_CHANNEL for each NRF/S ensor unit that is sending data to the Gateway. I have seen this specified sometimes in sketches in the forum.

I have managed to to get one DHT sensor and mini pro working via a NRF24+ radio link and reporting via the MySensors gateway and Domoticz but would like to add a few more sensors also reporting things like air pressure, air quality, lightning detection, wind speed direction etc.
Is there a guide/post on how I should go about adding additional sensors. How do I set up arduino mini pro sketches to send data to the Gateway from multiple sensor/mini pro/NRF units around my property. Do I need to worry about channels etc or will they conflict.

TIA
David

Thanks gohan, Reloaded Arduino IDE 1.8.2 and it now compiles without any problems and have it reporting temp and humidity to Domoticz. The reason I downgraded the Arduino IDE version was I had an Arduino Uno setup as a gateway but it would constantly disconnect and the solution I found on the forum was to use an earlier IDE version.

Cheers.

Hi, just fired up my newly purchased Sensebender GW and connected to my PC running Windows 10. Shows up as a USB Serial Device.

Installed in Arduino IDE 1.6.7 the following
Arduino SAMD Boards 32-bits ARM Cortex-M0+ vers 1.6.14
MySensors SAMD Boards vers 1.0.5

When I try to compile the stock standard GatewayW5100 sketch I get

C:\Users\David\AppData\Local\Arduino15\packages\arduino\hardware\samd\1.6.14\cores\arduino/Arduino.h:48:17: fatal error: sam.h: No such file or directory.

I have noticed that in the Sensebender GW webpage I read that
"be aware that Mysensors board files 1.0.4, is only compatible up to Arduino SAMD 1.6.11." I have tried downgrading to 1.04 and 1.6.11 but this did not help.

Can someone point me in the right direction please?

TIA Dave
