How to fix these 2 errors in my log, these keep coming back.

Version: 2021.1

Think the first one is asked many times and you should be able to find the answer easily.
.. but this is probably a good place to start:

And the second error is intentially as the Zwave device sends an illegal value so Domoticz is ignoring it. Illegal values happen sometimes due to communication issues within the Zwave network or with this particular device.
