Frequent changes of value z-wave device

Hello,

For some time I have frequent changes for one of my z-wave Nodes.

From OZW_Log.txt:

As a result OZW_Log.txt grows enormously as well as hass_db (because of state changes).

Greetings,
M

If it isn’t something you want to track, exclude it from your recorder, history, and logbook.
As for the OZW_Log.txt you can modify options.xml to turn off logging or change the log level:

<Options xmlns='http://code.google.com/p/open-zwave/'>
  <Option name="logging" value="true" />
  <Option name="SaveLogLevel" value="4" />
  <Option name="Associate" value="true" />
  <Option name="NotifyTransactions" value="false" />
  <Option name="DriverMaxAttempts" value="0" />
  <Option name="SaveConfiguration" value="true" />
</Options>

The Following Values can be used for the various LogLevel options above. Use the numeric value in options.xml to specify the actual log level.

value Logging Level
0 No Logging
1 All Messages
2 Fatal Messages Only
3 Error Messages and Higher
4 Warning Messages and Higher
5 Alert Messages and Higher
6 Info Messages and Higher
7 Detailed Messages and Higher
8 Debug Messages and Higher
9 Protocol Information and Higher

Thank you for suggesion.

Actually I prefer to have the same LogLevel for my z-wave devices. I have about 10 different z-wave devices (thermostats and wall plugs) and all of them worked simillar (and logged their state changes on predictable level).

For some time one of my z-wave wall plugs (Fibaro) started to raport (very frequent) value changes:
from 0,4W to 0,3W… and… again from 0.3W to 0.4W… and vice-versa.

I wondering what to do. Is there some global setting to reduce sensibility of state changes for particular z-wave devices?

Regards, M.

Check the Zwave options for your plugs, if there isn’t one, then likely there’s no way to resolve that.
