Hi all,

I'm having trouble getting all my flows rto show up in the layout. I have two flows but I can't get both to show up in the Layout.  
Been looking at a tutorial that says to select the proper group on each object but I can't see how to do that.  
Also, I am trying to set a switch to toggle but can't get that to work either.

I am controlling a Raspberry Pi Zero W. I am able to turn on and off an LED with two switches but cannot get the CPU temperature (using a parsing function and a gauge) .

Thanks in advance for your help  
Mike

I'm afraid you're not gonna get a lot of help unless you post screen shots and your flow (export it and paste between three ticks ```` code here ````)

There is barely anything to go on with what you have posted.

Some tips...

- Add debug nodes after every node and verify what you expect is correct.
- Be more specific
  - nclude the OS, node version, npm version, node-red version,
  - what nodes you're using,
  - what hardware you're using and communicating to
  - What you have tried and where you're stuck

- Check out examples and the cookbook (links at the top of this forum or search cookbook)
- Search this forum - there are many examples and tips

Hi Mike.

I too (as do many people) have a RPI.  
For me, getting the temperature is a command.

I put an `exec` node in the flow and enter this command in it to be run.  
`/opt/vc/bin/vcgencmd measure_temp| sed 's/[^0-9]*//g'`

The `exec` node has 3 outputs. I take the output of the first (top) output and put it through a `function` node with this in it:

```auto
msg.payload = Number(msg.payload)/10;
msg.topic=global.get('myDeviceName');
msg.topic ="TEMP/" + msg.topic;
return msg;

```

Then the message is on-sent to other nodes.

If the node wants the temperature, it just reads the `msg.payload`.

The `msg.payload` can then be sent into a `gauge` or `chart` node quite easily.

Hope that helps.
