Please filter obvious wrong sensor values

[pmbert]

From time to time I get very wrong sensor values. Now I have recognized a case where the z-wave message is clearly wrong and could be filtered by the receiver.

Device: Aeotec Multisensor 6, ZW-100 Application Version 1.7

Z-Way log:
[2019-04-25 15:32:54.712] [I] [core] Notification: device-info (device-temperature): {"dev":"ON-WZ Temperatur","l":"5787.5 °C","location":16} [2019-04-25 15:32:55.489] [I] [core] Notification: device-info (device-temperature): {"dev":"ON-WZ Temperatur","l":"22.6 °C","location":16} [2019-04-25 15:32:56.049] [I] [core] Notification: device-info (device-temperature): {"dev":"ON-WZ Temperatur","l":"5787.5 °C","location":16} [2019-04-25 15:32:57.757] [I] [core] Notification: device-info (device-temperature): {"dev":"ON-WZ Temperatur","l":"22.6 °C","location":16}
Please consider the temperatures above 5000°C.
These wrong values are caused by a wrong value size in the Z-Wave message: It is 3 Bytes, but should be 2 Bytes. 3 Bytes is obviously wrong, because it wouldn't fit with the message length.

The Z-Wave message:
