Haspmota Button .hidden attribute help

[GasTurbineMan]

My need is similar to this post https://github.com/arendst/Tasmota/discussions/16297

My display and code works. Now trying to add .hidden attribute to a button as I want to make the button disappear if certain condition is true.

I have this code in :"autoexec.be" for my trigger condition:
global.p1b44.text = string.format("%s",global.jdata["printer_state"])' 'if global.p1b44.text == "RUNNING" global.xyzenable = false else global.xyzenable = true end

Then in my "pages.jsonl"file is have this:
{"id":104,"obj":"btn","x":723,"y":403,"w":75,"h":75,"bg_color":"#4f4f4f","text_color":"#FFFF44","radius":0,"text":"XYZ","border_width":3,"border_side":15,"border_color":"#FFFF44","border_opa":210,"text_font":"montserrat-28","hidden":true} {"berry_run":"tasmota.add_rule('global.xyzenable', def (state) global.p1b104.hidden = state==false end)"}

My goal is to hide the button anytime global.xyzenable is equal to "RUNNING".

To me, your issue does not look to be about "hidden", but about the weird things you are doing. On a detailed level, your first part (code in autoexec.be) has two unbalanced single quote making syntax invalid, hence it is not clear what your autoexec.be actually is.

Next, it just does not work using a variable name as trigger in tasmota.add_rule. What you can do is to get rid of that berry_run part, and instead assign global.p1b104.hidden more directly without that detour around a "rule" to set it. Assuming that what you posted is only two lines from your longer autoexec.be, that could be a place to do that assignment directly without that global.xyzenable.

Maybe something like global.p1b104.hidden = global.p1b44.text != "RUNNING"

BTW. You could likely make this a bit simpler:
global.p1b44.text = string.format("%s",global.jdata["printer_state"])
That format function does not "do" anything....
global.p1b44.text = global.jdata["printer_state"]
If you had a need for formatting, it would also work with just format instead of string.format. And you also have f-strings for a more convenient syntax.

The "weird" things I am doing is not knowing how to properly submit code in a support post. The two lines in my autoexec.be file were:

global.p1b44.text = string.format("%s",global.jdata["printer_state"])
if global.p1b44.text == "RUNNING" global.xyzenable = false else global.xyzenable = true end

Replacing the 2nd line with:

global.p1b104.hidden = global.p1b44.text == "RUNNING"

achieves what I want to do.

You have provided the answer that I was looking for and I thank you. I am still trying to learn Haspmota and you have provided me 2 great tips.
