-This service will update a configuration parameter. At this time, it is not possible to update multiple partial parameters in a single call, but we hope to add support for that in the future.

 Let's use parameter 31 for [this device](https://devices.zwave-js.io/?jumpTo=0x000c:0x0203:0x0001:0.0) as an example to show examples of different ways that the `LED 1 Blink Status (bottom)` partial parameter can be set. Note that in places where we are using different values for the same key, the different values are interchangeable across the examples. We can, for instance, use `1` or `Blink` interchangeably for the `value` in all of the examples.

+This service will bulk set multiple partial configuration parameters. Be warned that correctly using this service requires advanced knowledge of Z-Wave to use correctly.

+#### Examples of bulk setting partial parameter values
+
+Let's use parameter 21 for [this device](https://devices.zwave-js.io/?jumpTo=0x031e:0x000a:0x0001:0.0) as an example to show how partial parameters can be bulk set. In this case, we want to set `0xff` to `127`, `0x7f00` to `10`, and `0x8000` to `1` (or the raw value of `4735`). 
+
+<div class='note'>
+
+When using the dictionary format to map the partial parameter to values, the cached values for the missing partial parameters will be used. So in examples 2 and 3, the service would use the cached value for partial parameters `0xff0000`, `0x3f000000`, and `0x40000000` because new values haven't been specified. If you send the raw integer value, it is assumed that you have calculated the full value, so in example 1, partial parameters `0xff0000`, `0x3f000000`, and `0x40000000` would all be set to `0`.

 ### Service `zwave_js.refresh_value`
 
 This service will refresh the value(s) for an entity. This service will generate extra traffic on your Z-Wave network and should be used sparingly. Updates from devices on battery may take some time to be received.
