No Transmissions After Reset

We are struggling to receive any transmissions from our 1-Channel Vibration Sensor Plus (PR55-61E). We are able to force a transmission to our gateway (MQTT micro gateway) by resetting the sensor, however after the initial transmission we don’t receive anything. I set the delay in the wifi micro gateway menu to one second, however other than that I’m not sure how to change/check transmission rates and our problem was not solved. Am I missing something here?

The minimum sampling interval for the vibration sensor is 5 minutes, with a default interval of 15 minutes.
Using an MQTT gateway with these sensors is not recommended.

The recommended gateway is enterprise gateway with node red
