Unable to send cmnd/nodemcu/power2 to relay

Hi All,

very beginner trying to control 8ch relay with nodemcu (running tasmota) relay 1 works but not relay2 or relay3 etc
mqtt broker/server setup - all ok
able to control 2 sonoff devices (running tasmota) - all ok

i guess what precisely i'm unable to do is send "cmnd/nodemcu/power2" using nodered. :frowning:

i read couple threads/guides and feel most people figure it out easily but not thick-heads like me. (i wish i could figure it out)

here's my flow today from node-red that i'm seeking help with. it would be a big favor if someone can tell me what should i do to fix it. all i should send is cmnd/nodemcu/power2 with payload ON/OFF. Attaching 2 pics hoping someone can help me out.

not familiar with much programming at this stage. sorry

Your flow contains only a switch node
and your inages are too small to read. Please do a copy/paste of the logs

When pasting in logs use the </> button so that the forum does not mess with the formatting.

You are sending to the wrong topic. It must be cmnd/nodemcu/power2 and not power
Look at you log.
Capture

Yes I saw that. But couldn’t modify the message on nodered

I’m afraid I tried to paste the picture for the logs taken and topic mentioned on tasmota webpage but this forum limited me to paste only 2 attachments.
I’ll paste in text fresh logs

Despite what i do to modify It to power2 It goes as power1

Paul,

sharing below the fresh logs

Below is my current flow, no matter what switch i press it sends cmnd/nodemcu/power always...and turns on relay 1 :frowning:

Evert,

is there a way to modify the command sent to nodemcu

When pasting a flow here you have to use the </> button to stop the forum from messing with the format. Otherwise it is not importable.

Colin,

i think i tried. i'm sorry if it messed up still

pasted again using </>

is there an example/sample that you can paste where you've 2 or more relays with topics/commands modified.

i tried to understand the modification of msg.payload which may do the trick using function node...but i couldn't get it

This works fine for me to switch POWER2

At the top of the edit box you type into on the forum there is a button showing </>. That is the button to use. I will edit your previous post to fix it for you.

YAY !!!!!!!!! This one did the trick :slight_smile:

i wish you could teach me. :smile:

i guess what i was doing was too much wrong.
1- i was using sonoff/sonoff-advanced (nodes) instead of mqtt in/out
2- Also i wasn't using set topic for example..was willing to find some how-to
3- on top of everything i was confused when i started exploring similar issues. i saw people trying to use maybe function node for modifying the msg.payload and so advanced stuff that i left the grip on the ground.

here's my current flow working perfectly (to see the switch icon, i had to choose default icon.)

Using sonoff with tasmota was easy for me. along with nodemcu running tasmota i got stumbled literally. This example really got me started again.

i am thankful to be a part of this forum.

Again you have not used the </> button at the top of the forum edit window. Did you see my last post?

terribly sorry Colin.

now i see what you mean. didn't know it. couldn't find it before.

will take care of it. appreciate your guidance.

No problem, most things are obvious once you know how :slight_smile:
