@carywin Yes I know. I had my own "firmware" for few years but I want to use something mainstream that will be easier to maintain (by someone else :) ).

@8667 That is inherently hard to state firmly due to so many variables. How much debug do you want, what libraries do you want to include, what software version do you plan to use, and so on.

@8667 yes. Just comment MY_RADIO_NRF24 in the MQTT gateway example. Then present your sensors and send their data like any other node. From the build page (my emphasis) The W5100 MQTT gateway sends radio network (or locally attached sensors) data to your MQTT broker.
