Hi,

i am a very new user with node-red.

i tried to create an easy flow.  
Plan:  
if the lamp is on, the energy switch go on, the lamp is of, the switch go off.

```auto

Hi, welcome to the forum.  
I see that you are using 2 nodes which do not form part of the default installation, so that means that other members would need to install them in their own installation so that they could load & test your flow. This discourages members from offering help, therefore it is always better (if possible) just to post the part of the flow which you are having trouble with.

PS we call that a 'flow', as it's a collection of nodes that are joined together.

hi,

i changed the name.

i can upload screenshots if it helps.  
Flow:

 ![2020-01-16 20_17_24-Window](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/0/b/0b82759051f52f9b4c2cf3bf19add2106377d4f7.jpeg)  
Switch:  
 ![2020-01-16 20_17_17-Window](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/c/7/c78ff7432d4934a2e8c754bd6df24362f01e6673.jpeg)

Change nodes are only delete payload and add a new with "on and off" for mqtt switches.

Log:  
This part runs correct:  
16.1.2020, 20:16:24[node: 47fcaf07.62706]  
msg.payload : Object  
{ **on: true** , brightness: 44, reachable: true, rgb: array[3], hex: "ffbb5c" … }  
16.1.2020, 20:16:24[node: 47fcaf07.62706]msg.payload : string[2]  
**"ON"**

This part doesnt run correct:  
16.1.2020, 20:16:30[node: 47fcaf07.62706]msg.payload : Object  
{ **on: false** , brightness: 0, reachable: true, rgb: array[3], hex: "ffbb5c" … }  
16.1.2020, 20:16:30[node: 47fcaf07.62706]

**"ON"**

Have you tried setting the second switch rule to 'otherwise' (instead of !=), so it tests for rule number one first, and if it does not match, then it will use rule number two.

or

`== msg.payload.on:false`

If i change to "otherwise" all is similar.

if i change to " `== msg.payload.on:false` " i have doubleswitch on off:  
 ![2020-01-16 21_17_07-Window](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/d/f/df6ff9cc9ab22ed34d355cccac26036dd27659d2.jpeg)

both (on and off) move by switch lamp on or off.

it make no sense for me. why the switch dont work like a switch?!?!
