Hello, I would like to separate the two values of an object.  
I'm trying with the split node, but it doesn't work.

Thanks

Connect the MQTT to 2 separate change nodes (in parallel). The first one should copy payload.temoeratura to payload, other one should copy payload.humedad to payload

But first ensure you need to separate them. What do you want to do that needs that?

Using a split node you can copy the property name (key) to any message property you wish. You can then use that property in the switch node to route the messages.  
e.g.

```auto
[{"id":"49fed7b68e0eedad","type":"inject","z":"d1395164b4eec73e","name":"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"my/test.topic","payload":"{\"humedad\":50,\"temperatura\":20}","payloadType":"json","x":410,"y":4920,"wires":[["417f8eab2d2c0461"]]},{"id":"417f8eab2d2c0461","type":"split","z":"d1395164b4eec73e","name":"","splt":"\\n","spltType":"str","arraySplt":1,"arraySpltType":"len","stream":false,"addname":"key","x":570,"y":4920,"wires":[["f8527ef2a529d4cb"]]},{"id":"f8527ef2a529d4cb","type":"switch","z":"d1395164b4eec73e","name":"","property":"key","propertyType":"msg","rules":[{"t":"eq","v":"humedad","vt":"str"},{"t":"eq","v":"temperatura","vt":"str"}],"checkall":"true","repair":false,"outputs":2,"x":730,"y":4920,"wires":[["87409c24e5857a1b"],["5d5853ad82a90c3d"]]},{"id":"87409c24e5857a1b","type":"debug","z":"d1395164b4eec73e","name":"debug 2481","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"true","targetType":"full","statusVal":"","statusType":"auto","x":930,"y":4880,"wires":[]},{"id":"5d5853ad82a90c3d","type":"debug","z":"d1395164b4eec73e","name":"debug 2482","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"true","targetType":"full","statusVal":"","statusType":"auto","x":930,"y":4960,"wires":[]}]

```

Or use the `msg.parts.key` that the split node creates.  
e.g.

```auto
[{"id":"49fed7b68e0eedad","type":"inject","z":"d1395164b4eec73e","name":"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"my/test.topic","payload":"{\"humedad\":50,\"temperatura\":20}","payloadType":"json","x":410,"y":4920,"wires":[["417f8eab2d2c0461"]]},{"id":"417f8eab2d2c0461","type":"split","z":"d1395164b4eec73e","name":"","splt":"\\n","spltType":"str","arraySplt":1,"arraySpltType":"len","stream":false,"addname":"","x":570,"y":4920,"wires":[["f8527ef2a529d4cb"]]},{"id":"f8527ef2a529d4cb","type":"switch","z":"d1395164b4eec73e","name":"","property":"parts.key","propertyType":"msg","rules":[{"t":"eq","v":"humedad","vt":"str"},{"t":"eq","v":"temperatura","vt":"str"}],"checkall":"true","repair":false,"outputs":2,"x":730,"y":4920,"wires":[["87409c24e5857a1b"],["5d5853ad82a90c3d"]]},{"id":"87409c24e5857a1b","type":"debug","z":"d1395164b4eec73e","name":"debug 2481","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"true","targetType":"full","statusVal":"","statusType":"auto","x":930,"y":4880,"wires":[]},{"id":"5d5853ad82a90c3d","type":"debug","z":"d1395164b4eec73e","name":"debug 2482","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"true","targetType":"full","statusVal":"","statusType":"auto","x":930,"y":4960,"wires":[]}]

In order to send separated values to influxDB.

Why do you want to send them separately to InfluxDB? You could store them in one measurement at the same time.

Which version of InfluxDB are you using?
