Mysensors impossible to add sensors

Hi, I have create a wifi gateway with a wemos D1 R2, it’s ok.
I create the plugin and parameter the ip adress and port, vera says it’s connected.
I create a sensor with a arduino nano for watermeter but when i make in inclusion mode and i power up the sensor, no hapend and he don’t create sensor. do you have an idear ?

I test with another type of sensor than a Motion sensor but it’s the same.

There are different version of the gateway plugin on GitHub, and the protocol version did change at one stage to add security. Are you sure your versions between gateway and device match?

Perhaps also try the MySensors forum itself for help.

Hi, final i find the problem! I don’t active inclusion in gateway arduino programmation. Now when I start inclusion mode it says number of mode to add.
Thanks for your help.
