Button/WS Limits?

[CommanderB]

I am butting up against some odd errors which I have been going round in circles on. This is a simple example of one of the issues -

I can write to a button when using hard coded context, but errors when using the sd output node (which works for all other buttons).

This works

And msg.payload sent back to the WS is

When I change this to use the sd output node configured as follows

The node errors (and the debug node doesnt fire) as below

I have similar problems when trying to write an image to the button.

I also seem to have problems when I configure a 5th WS node, everything stops working. Removing the 5th WS restores the 4 working button/WS flows to work on the SD. I will try to demonstrate that in a different message

Can you check the content of Context Data for variable streamDeckContexts ?

if btnTime is unknown it's probably because no sd in node ever saw that node willAppear, keyUp, etc. before

Yup, its not there, nor is btnTemp or, another one I am hardcoding around -

This is the flow that captures button presses, btnLight works. (Key is a subflow with an sd input and switch on key down/up/willAppear which is used in several places)

And pressing btnTime or btnTemp works.

So its the subflow!!! My bad. The scope of streamDeckContexts isnt making it out of the subflow -

Changing to this

Has it working -

Sorry. Thats me not thinking/fully understanding scope in Node-Red

States should actually be managed by a configuration node, node in the flow, that would be the proper way to do it, I didn't know better at the time, I'll work on a fix
