A set of Node-RED enhanced boolean logic and utility nodes, flow interruption, blinker, invert, filter, toggle etc.., with persistent values after reboot. Compatible also with Homeassistant values.

<p>Outputs the Kalman filtered input.</p>

Please refer to [this](https://github.com/wouterbulten/kalmanjs) link, on how it works.  

|Property|Description|
|--|--|
| Input | It's the msg property to be evaluated. *By default, it is "payload", but you can also specify other properties, for example "payload.value"* |
| r,q | Kalman's parameters to be set. |
| Translator Input | Translates the incoming <code>payload</code> value, to true/false. This allows the compatibility with, for example, **HomeAssistant** nodes. |

<br/>

### Inputs

: reset (any) : by passing msg.reset, the Kalman filter will be reset.
: payload (number) : the payload containing the number. If you've changed the incoming evaluation property in the ***Input*** field, the number to be evaluated must be put in such message's property, instead of the *payload* property.
