dht sensors are not very accurate anyway

I knew that they are marked. But I didn't know the polarity. It could have been possible that Cap- goes to VCC on the radio, since in a full capacitor, there is a lack of electrons on Cap+, and very much electrons on Cap-, and also a lack of electrons on VCC, and very much electrons on GND, and the many electrons on the negative side should match the lack of electrons on the matching side of the other device - you see my point? So I was unsure. But Cap- to GND is clear and explicit, yeah.

@simonszu said in Need help with initial setup: It looks like it is restarting some times There were some issues with the w5100 and some ide versions causing the gateway to constantly re start Have a look at GatewayW5100 - unable to get working w/ v2.0.0 MySensors 2.0 Ethernet gateway Atmega+W5100) restart all time

There is no pairing. You could use deterrent channels or (if security matters) indeed have a look at signing.

The easiest way to install the MySensors library is to use the Board Manager. See https://www.mysensors.org/about/arduino#installing-the-sensor-libraries for instructions. You'll need to delete the folder that was added manually first though.
