I use the colour picker, it sends a hex code. In a function node, I convert that to a value. I believe that is what my RGBW strip requires (debug node 7). As I could not get the function node to send it as payload.value (it gives an error cannot convert to object) I tried using a change node to set payload.value to payload. The same error "Cannot set property of non-object type: payload.value"
(I have the same problem when I try to use sliders to control the strip)
I copied the path from debug 7 with the value (in this case 1151), and its payload.value
What am I missing ? Going round in circles for ages and cant work it out

looks like an issue in the change node, or possible the function node, please export your flow.

I think you need to use the "Compact" option when you Export your flow.

You need three back tics on a line before your code and again on a line after your code (I've changed it so you can edit your post and see what I did)
To get the flow to come out in one line, when exporting

Got it. But I dont have these ticks on my keyboard, I copied and pasted them (UK keyboard)

Well, whatever you have done - you have achieved the correct result.

If you're in the UK, I bet you do have the 'back tick' character on your keyboard (under the Escape key).

Back to my issue. I have done more testing. In my system (Homeseer) the RGBW strip has 5 devices. A custom rgb, red, green, blue and white. Looking at the debug from their nodes, the all have numerical vales in payload.value
If I use a inject node to send a payload.value to one of the red green or blue, that works. They dim to the correct value. the custom rgb, it shows a numerical value in the debug too, but if I send it via a inject node, nothing happens.

Ooops. Yes.

Looks like you are trying to set an object property to a number, try move instead in change node.
Move `msg.` `payload`
to `msg.` `payload.value`
What format are you trying to send to the HA node? As you get a hex string from the colour picker, then parse it to turn it to a decimal number, seems strange.
I doubt the function node is required.

I have done some more testing with a inject node. I am not sure what the custom rgb node wants. If I send a numerical value nothing happens. If I send hex, I get a unexpected response.
If I set the custom rgb via Homeseer, it shows a numerical value in payload.value, but if I try to set it to that value, it doesnt work. Does not make sense. I need to find out what to send to it on the Homeseer forum.
In the meantime, I can try to get the sliders for rgbw working. The slider sends a message, payload 87
Now, I thought it would be easy to get that into payload.value, but it isnt. Same error as I had before, "Cannot set property of non-object type: payload.value"

A change node which moves the value and adds topic control has done it.
