I'm new to the Node RED world. This is a working sequence but it is just too long and hard to read and maintain. Since this sequence is just simulating button press, can I use one function node for this entire sequence? [Screenshot 2020-05-22 at 8.03.47 PM] UPDATE Thanks @Steve-Mcl 's suggestion …

Prossibly, but i suspect you are taking actions on each of these buttons so you might have to live with it (although it dowsnt have to be in one straight line - you could use link in/link out nodes and re-arrange it) However, my question is - what on earth happens at the end of that flow? It looks…

Thanks for your advise. I think using LINK node would be helpful for nodes arrangement. To answer your question, I am using an LG OLED TV so this sequence just turn off the screen. the TV is running on its webOS system but there is no interface to turn off the screen directly :frowning:

Are you sending IR commands? or talking over http? or other?

I can use home assistant to control the TV but the functionality is limited https://github.com/bendavid/aiopylgtv/blob/master/aiopylgtv/endpoints.py . I believe the LGTV node would do something similar. It can communicate HTTP but i believe this setting is not exposed to the outside world. The remote…

[image] Steve-Mcl: Cant you just inspect the final value, capture that & send it directly? How can I do this? the exposed API does not seem be able to do it, aiopylgtv/aiopylgtv/endpoints.py at master · bendavid/aiopylgtv · GitHub .

The node @bakman2 refers to states it can do this... [image] give it a go

sorry, let me be clear. I'm trying to turn the screen off not the TV off.

So like blank the screen? (but leave TV on - for say listening to music?)

You are using home assistant nodes and have configured each node to perform some action, correct ?
The information in the field names in the call-service node can be set via another node (inject, change, function, etc).

read/watch the documentation of node-red.

Your flow can be reduced to 3 nodes.
