@Yveaux do you also use Grafana in order to visualize the data? I am not sure what fields/attributes are necessary despite "time" and "value" for a binary sensor.

Had the same Problem! I'm totaly new to MYSENSORs and my gateway runs on an Arduino pro mini 8MHz attatched to a Pi. Funny thing was that the controller is able to send data at 115.2kbaud but can't read at that speed when clocked with 8MHz ( as explained here : http://forum.mysensors.org/topic/1483/trouble-with-115200-baud-on-3-3v-8mhz-arduino-like-serial-gateway-solution-change-baudrate). Solution: Set your baudrate to 57600 end reupload the sketch. Took me quite a while bevor I figured that one out. Hope that helps anyone how encounters the same Problem.

I have added a device editor to the server. It uses the sensor types as a group and the sensor variable as the control. Group (sensor): Control (sensor variable): This will be my last post here because my controller has got it's own controller page
