Passing input_text params from HA to ESPHome printf lines

ESPHome
1

I have added a ILI9341 TFT display to one of my ESPHome devices.
It works fine when setting x/y positioning, fonts, colors etc. directly in the lambda printf line.

Now I would like to get the printf parameters from HA to control :
x & y position
font
font size
font color
text string

I am using the HA input_text helper, and that works fine for getting the text_string (input_text.displaytext)

but I don’t know how to get the others ;
x_pos
y_pos
font name
font size
and font color.

Googling & trying to find a solution in HA Community didn’t help…

Regarding fonts/font sizes, & colors, its ok if the input_text content just “points” to my predefined fonts/font sizes & colors in the ESPHome file

Is there an easy way to do this ??

The first line in my lambda code works fine , but I would like the second lambda line to execute by getting all parameters from the input_text values…

I am not sure that the positions are templatable. I can’t see any examples of it.printf which has a templated <x> and <y> in this page Display Component — ESPHome

If you have an example of it being done, please post a link to it :slight_smile:

No, sorry I dont have that,
I have tried a lot of possible solutions, with no luck, so this is just a “wishlist”…
If it would be possible to template only some of the parameters, the priority would be :
#1 Textcolor
#2 Font
(getting the textstring from input_text works fine)…

So if it would be possible to template color & font, that would be great.

In that case (even if its not possible to template x&y positions, a quick & dirty solution could maybe be, just add all the lines that should appear on the display as printf-lines (with fixed x&y positions), and then set the textcolor for the lines that should be hidden, to the same color as the background to hide them.

And when they should appear just change the textcolor again for these lines, and “hide” the others"…
Not very elegant, but a possible workaround ??

(Looking forward for replies to a better solution…)
