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. ☹

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)

> [@Controll Tasmota-Client via MQTT using Node-Red?](https://discourse.nodered.org/t/controll-tasmota-client-via-mqtt-using-node-red/24700/2):
>
> As described in the Info panel for the MQTT Out node, the value to publish is picked up from msg.payload. So all you need to do is to set msg.topic to the MQTT topic you want to send to and set msg.payload the value you want to send ("ON" for example) and pass it to the MQTT Out node.

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.

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

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

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

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

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 🙂

i wish you could teach me. 😄

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.)

```auto
[{"id":"6300df8d.87cc4","type":"ui_switch","z":"f087d4d8.c328d8","name":"","label":"R4","tooltip":"","group":"bd562bdd.0a98e","order":2,"width":0,"height":0,"passthru":false,"decouple":"true","topic":"","style":"","onvalue":"ON","onvalueType":"str","onicon":"","oncolor":"","offvalue":"OFF","offvalueType":"str","officon":"","offcolor":"","x":270,"y":540,"wires":[["be2a1503.87f508"]]},{"id":"bd562bdd.0a98e","type":"ui_group","z":"","name":"8Relay","tab":"6e3d9ae8.7efe4c","disp":true,"width":"6","collapse":false},{"id":"6e3d9ae8.7efe4c","type":"ui_tab","z":"","name":"8Relay","icon":"dashboard","disabled":false,"hidden":false}]

```

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?

No problem, most things are obvious once you know how 🙂
