A new Attribute DbLogExclude will be propagated
to all Devices if DBLog is used. DbLogExclude will work as regexp to exclude
- defined readings to log. If a MinInterval is set, the logentry is dropped if the
+ defined readings to log. Each individual regexp-group are separated by comma.
+ If a MinInterval is set, the logentry is dropped if the
defined interval is not reached and value vs. lastvalue is eqal .
Example
attr MyDevice1 DbLogExclude .*
- attr MyDevice2 DbLogExclude state (floorplantext|MyUserReading):300,battery:3600
+ attr MyDevice2 DbLogExclude state,(floorplantext|MyUserReading):300,battery:3600
