  Regexp that must match your devices, readings and values that contain
  the JSON strings. Regexp syntax is the same as used by notify and must not
  contain a space.
  
  




• 
  
  
  Optional: This regexp is used to determine whether the target reading is
  converted or not at all. If not set then all readings will be used. If set
  then only matching readings will be used. Regexp syntax is the same as
  used by notify and must not contain a space.

  Examples:
  
  
  
  Source reading:
  
  device:reading:.{.}

.WifiIOT.:sensor.:.{.}

sonoff_.:.:.{.}

dev.:(sensor1|sensor2|teleme.):.{.}

(dev.|[Dd]evice.):json:.{.}

(devX:jsonX:.{.}|devY.:jsonY:.{.Wifi.{.SSID.}.})
  
  
  
  
  Target reading:
  
  .power.

(Current|Voltage|Wifi.)

Attributes






• addReadingsPrefix
  
  Add source reading as prefix to new generated readings. Useful if you have
  more than one reading with a JSON string that should be converted.
  



<li><b>disable</b><br>
  Used to disable this device.
</li><br>
<li><b>do_not_notify</b><br>
  Do not generate events for converted readings at all. Think twice before
  using this attribute. In most cases, it is more appropriate to use 
  event-on-change-reading in target devices.
