I'd like to read out all my onewire sensors at once, but only get one?

```auto
[{"id":"d6d27eeb.c278a8","type":"inject","z":"97b191db.235b1","d":true,"name":"Temps","props":[],"repeat":"6","crontab":"","once":true,"onceDelay":0.1,"topic":"","x":400,"y":200,"wires":[["11c1a21e.e71a3e"]]},{"id":"11c1a21e.e71a3e","type":"owfs","z":"97b191db.235b1","name":"1-wire","uncached":false,"mode":"read","host":"192.168.78.10","port":4304,"paths":["28.282DE9050000/temperature","28.34A2E9050000/temperature","28.7A3BEB050000/temperature","28.EEA8E9050000/temperature","28.5901EB050000/temperature","28.DD2BE9050000/temperature","28.D3DBEA050000/temperature","26.E1CD92010000/temperature"],"x":650,"y":200,"wires":[["229dbc37.39ee5c"]]},{"id":"229dbc37.39ee5c","type":"debug","z":"97b191db.235b1","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"false","statusVal":"","statusType":"auto","x":880,"y":200,"wires":[]}]

```

This leads to multiple read-outs from the last sensor:

Since your flow requires the sensors on your network, this is all we see... so no idea how to even begin...

Sorry, I guess, you have to have onewire setup and running for this, yes!

because, I can check all onewire-endpoints right here:

And I expected to have the selected nodes to be given out as individual msg.topics/msg.payloads, but as it seems, they're read out and only the last one gets spit out...?  
but perhaps I did something wrong, that's why I'm asking.

As this is a node specific issue, perhaps best to check the contribs git-hub page... I found a similar issue there...

When your node returns data, stick a `debug` node (set to show COMPLETE MESSAGE) and paste that.

Not a screen shot!

This **may** help people understand what is going on.

Also see my post in [your other thread](https://discourse.nodered.org/t/adding-a-delay-to-injections/48439/9). It is best not to start two closely related threads at the same time, it just causes confusion.
