Set RGB Color using MQTT

[gavraq]

I am trying to set a color for a RGB light using MQTT. I know that I need to use the cmnd/Topic/Color command but I cant seem to get the message formatting correct. Here is my current flow

You can see that the message comes out as an object whereas I believe it needs to come out in this format: (68, 106, 255) which should then go in to the MQTT in node.

[The Delete a node removes one of the variable from the color picker which has r,g,b and a values whereas I believe the Tasmota is just expecting (r, g, b) ]

and here is my rather crude (and unsuccesful) attempt at using a change node to try and format correctly

Can someone help please.

the colour picker can send a string instead of an object - that may be easier to reformat as you want.

yes closer...although the a-value is still there. How can I remove it?

I have set the colorpicker to output format hex8, you can send this direct to tasmota.
