This is one of my babies.
I've worked on it for a long time and it is getting better - I hope - than it was.
This is a bit more _strict_ in it's inputs, but offers a lot of handy stuff if you are dealing with devices that may or not be available all the time.
It can also be used to control `gate` nodes (foreign) but they are handy sometimes, so the output `topic` is in the subflow's settings.
NO FOREIGN NODES IN THIS SUBFLOW.
Just to declare that.
Give the _docs_ a once over too.
See if I haven't left anything important out.
(I say that because I just spent a lot of time to put something in I had already done and forgotten I did it.)
Walk through of what it is all about:
You have a standard `button` node.
You want to use it to TOGGLE something on/off.
Originally that was a `gate` node, but things have evolved to now include more stuff.
Node _properties_:
`start mode` - determines if the output (upon deployment) is OFF or ON
`Off text` - is what is shown in/on the button when the OFF mode is active.
`OffCLR` - is what colour you want to use in/on the button. Font/background. Your choice.
I would nearly include two colours, but.....
`On text` - is what is shown on the button when the ON mode is active.
`OnCLR` - as above but for ON condition.
`OFF` - the payload sent out when OFF condition active.
`ON` - the payload send out when ON condition active.
`CTOPIC` - if using the `gate` node set the `topic` to identify to that node it is a control message.
Yeah, I know you could just stick a `change` node.... but as I did use this a LOT of controlling the `gate` node, it seemed beneficial to put it in there.
I hope the _docs_ are sufficient to explain the rest of the workings for messages accepted.
And how to configure the `button` node to display the right stuff.
There is the _option_ with the `msg.enabled` to change between `true` and `false`.
That is if you want to DISABLE the button for any reason.
If it i`disabled` is shown on the `button` node.
Work maybe could be done there.
There are also options to RELOAD and RESEND.
RELOAD loads the _DEFAULT_ condition.
RESEND forces the node to output the existing condition - in case you redeployed the dashboard and it's state got wiped.
