I have built a ESP8266 Gateway and I connecting a BME280 sensor. It report everything right with a serial gateway but with the new wifi gateway it not reciving the battery percent. I look in the serial monitor at the gateway and where is no battery data.

@Boots33 Will you please upload your complete code. It is difficult to see the finale solution then I read all the posts.

I allso downloaded 2.0 and find out that a lot of exaples are missing. And then I try to go back to 1.5 files are missing in .zip.
Also the file Mysensor.h is renamed to Mysensors.h and in the build section is the old code.
