This attribute takes a comma-separated list of reading: Currently the following values are supported: See the documentation of the attr command for examples.
Only necessary in exceptional cases. On both occasions the key will be first compared directly with the text, and if it is not equal, then it will be tried to match it as a regexp.
There are global attributes that are used by all devices and local attributes that apply to individual device classes only. After the black-out period has expired, the reading is updated with a value that is calculated from the values and timestamps of the previously ignored updates within the black-out period as follows: These can be set by means of the attr command, displayed with the displayattr command, and deleted by the deleteattr command.
If set, the timestamps of the listed readings will not be changed if event-on-change-reading is also set and it would not create an event for this reading. A device can appear in more than one room, in this case the rooms have to be specified comma-separated. This attribute is evaluated each time a reading is updated.
The value of this attribute consists of a list of space separated values, each value is a colon separated pair.
If not set, its value is taken from the state reading. If a reading is listed in event-on-update-reading, an update of the reading creates an event no matter whether the reading is also listed in event-on-change-reading. You may use regular expressions for reading.
If any of the attributes is set, no events occur for updates or changes of readings not listed in any of the attributes. If set, then every word in the argument is replaced by the value of the reading if such a reading for the current device exists.
If an optional [: The value for the global device is a default for other devices without own verbose attribute set. The attribute takes a comma-separated list of readings.
If this attribute is not set then the device type is used as the grouping attribute. The precedence of event-on-update-reading and event-on-change-reading is as follows: The second part usr is the other direction, if the user specified open 10, the device will receive on When using regexps in the usr part with wildcards, the fw part must be filled with the exact same keys to enable a correct display in the FHEMWEB set dropdown list in the detail view.
The "set magic" described here is also applied. If both attributes are not set, any update of any reading of the device creates an event. If set, updates for the listed readings are ignored and associated events are suppressed for a black-out period of at least interval seconds downsampling.
If set, only changes of the listed readings create events. If set, only updates of the listed readings create events. You may use regular expressions in that list. Device specific attributes Device specific attributes are documented in the corresponding device section.
A device can appear in more than one group, in this case the groups have to be specified comma-separated. Be careful not to overwrite additional global attributes previously defined by yourself or a device.Tour Start here for a quick overview of the site Help Center Detailed answers to any questions you might have Meta Discuss the workings and policies of this site.
