I wrote a follow-up, to enable secure MQTTS with TLS connection: Secure MQTT integration between Node-RED and The Things Network .

In the blog, I used a split, and two change nodes, to turn payload object into a simple boolean. Sticking to the principle of using graphic nodes in a workflow design.

Another way to retrieve the LED status from the payload, and send it on as a boolean payload: using a js function. A bit of programming (not a lot)

function's javascript code:

Opinions on what a flow developer should prefer, are welcome...

A bit of playing around with subflows and dashboard elements.

Custom Font Awesome icons for the on-off indicator:

Top is the the standard switch UI. Bottom is a custom one.

Settings:

Group related nodes in a subflow.

In this case, I grouped all dashboard elements. They were starting to clutter up the main flow.

Original (simulated - I didn't capture a screen before I made the changes):

Subflow refactor:

main:

sub:

This is a full overview of the main flow:

Opinions may vary.
I personally prefer the standard switch indicator to the custom one.

Subflows make sense, I think.
My example may be a border case. The full flow wasn't cluttered (yet).
Grouping all dashboard elements into a dashboard subflow has some merits. The subflow has the full payload. I can add additional indicators without having to reorganise the main flow.

Your milage may vary ...

I haven't solved the MQTT TLS connectivity yet, but implemented another security measure:

Node-RED over https only:

last line in the log is the (still plain mqtt) connection to The Things Network's MQTT service.

Plain http requests to Node-RED's editor or dashboard will fail:

Nice update Jan.

More info is available in the payload. Capture of 3 connections:
