Monitoring a critical parameter of a trailer and issuing a severity warning including: monitoring the critical parameter to be within one of a plurality of bands and issuing a different level of the severity warning based on which band of the plurality of bands the critical parameter falls into, wherein the critical parameter includes at least one of tire pressure, tire temperature, and brake temperature; and increasing an alert level of the severity warning by one, every hour, when the monitored critical parameter indicates continuous increase or decrease over time.

The present invention relates to a monitoring device (100) comprising at least one measuring device with a temperature sensor unit (110) for wheel hub temperature and/or with a tire-pressure sensor unit (1501) and comprising a transmitting unit (115). The tire-pressure sensor unit (1501) is designed to sense a tire pressure of at least one wheel tire of a wheel of the vehicle; more particularly, the tire-pressure sensor unit (1501) is designed to draw electrical energy from the transmitting unit (115), which is external to the tire-pressure sensor unit (1501) and/or is fastened such that the transmitting unit can be spontaneously detached, or to output sensed data to the transmitting unit, and the tire-pressure sensor unit (1501) has a fastening apparatus, which is designed to detachably frictionally attach the tire-pressure sensor unit (1501), in a fastening position, to one or more portions of a wheel hub (120) of the wheel, a hub sleeve (130) of the wheel, a wheel rim (122) and/or a wheel nut (200) of the vehicle. Furthermore, the monitoring device (100) comprises the transmitting unit (115), which can be frictionally attached or fitted onto the wheel hub (120) of the wheel or onto the wheel rim (122) such that the transmitting unit can be spontaneously detached; more particularly, the transmitting unit (115) is designed to wirelessly transmit a sensor signal representing the tire pressure and/or the wheel hub temperature, so that the tire pressure and/or the wheel hub temperature can be monitored.
