output as msg.payload

[bakman2]

Nice node, thanks.

Why is the message output send as msg from the scanner ? There is no way to handle this output without first changing it to msg.payload first.

Can you elaborate "There is no way to handle this output" a little bit? msg.payload is just a property of msg object. What are you not able to do without it?

[bakman2]

Node-red assumes msg.payload with all nodes, ie debug, switch, change. If you try to feed the scanner through a switch node, you cannot filter, because there is no payload, only msg

Now, after having a deeper look, I also think that, it will be more convenient to output as payload. I will update it in a way that you requested. Expect a new release in 10 days.

Thanks, thats ok, I can submit a pull request with the changes.

[hkayann]

Yes please. Thanks.

Accepted the pull request, hence closing this issue.

Maybe its me, but i still can't use the switch node on this. It works when i put the output of the scanner node in an inject node though (setting the msg.payload in front and removing the payload from the scanner output. The only difference i can see is that the _msgid is behind the payload, not in front of it. Tested the whole day. From my little experience it should be as easy as copying the path of the value, insert it in the switch node property and copy the value, set it to number and set it to ==. I've set the scanner to local name "Flower Care"...

[dingausmwald]

We all do mistakes, I am glad you figured it out.
