Dashboard template - want to send icon by msg.payload, but doesn't work

Hi, it must be something obvious as I can't find solution.

I try to use template to show icon
if I enter to template

i have nice fire icon.

However, I want to do it programmically, so I try to inject message with
msg.payload = "fa fa-fire"

and use template as
which doesn't work.

Any thought?

Node red v 2.2.2 on raspberry

It is already set us string type in the Debug node
No need to use the extra quotes that you have around the string "fa fa-fire"

Use :

thanks for response,

right, that works ... but I have now problem with refresh {?}

once I deploy flow, it doesnt work,

I have to switch between dashboard groups - there and back - viola - works.
Can I do that in the code?

Many thanks

maybe you need to give your icon an initial size with style ?

However works great, and good study material.

Thank you
