Sorry folks, the hamster in on holidays upstairs.
Here's what I have so far.
Alas things evolved and it became more difficult.
That worked ok and does work IF the device has only ONE output.
I now have a device that has 3 outputs.
Which throws a spanner in the works with the topic.
So I have the subflow now with this:
So the power is entered (numeric only) and I want to append it to the topic - after deleting the 1 which is there now.
So......
Ideally it would be something like:
J: topic&'/cmnd/power'$power
But I am not sure that is the correct syntax.
Yeah, ok, it won't break if I try it.
But I fear my understanding is so far wrong/off, it isn't really going to be working for me.
Thanks in advance.
P.S.
I just realised I could (maybe) do it this way:
topic&'/cmnd/power'&power in the last line of the change node.
Just want to double check myself.
I am about to try it, but if you wouldn't mind confirming for me anyway.
Ok, that didn't work.
So this is a hack that works.
Yes, it is sloppy, but it works - yes?
