Z-wave sensors spamming logbook

Hi, I have 3 z-wave that is spamming the logbook with updates, it is 2 fgd-212 dimmers and one noname wallplug.
And i should also mention that i have more of these fgd-212 dimmers that is not logging these entries.

zwavedevices

I have excluded them from the log now, but i still wonder why they are showing up. Should i be concerned that there is something wrong with these devices?
