This tip may already be known.

I have an Arduino uno and an breadbord to make tests of new projects but got tired
of to have the radio "nRF24L01+" hanging loose in the wires.
I then find that there was an adapter to the ESP8266-01, "WiFi Module", to be used
on an breadboard. The pin configuration is wrong so I put a label on the adapter
and numbered the pins in accordance with nRF24L01+, pic 1. I also have to desolder the
capacitor on the adapter, pic 2, this could be of diiferent kinds and other places.
And now the radio fits on the breadboard!

@dbemowsk I'm have just started with mysensors and have configured a soil moisture sensor together with openHAB.
To get it to work I used the sketch for soil moisture but present the child as S_HUM and send the reading as V_HUM.
