On my android smartphone I have assigned following Tasmota commands http://192.168.178.91/cm?cmnd=Power%20on http://192.168.178.91/cm?cmnd=Power%20off
to 2 icons namen ON and OFF to switch a Tasmota device on and off by a
single icon touch only.

This works very fine, except that the device's answer page is buffered in Firefox, and when I switch ON and OFF and again to ON the second ON does not send again the command to the device but reads the answer page from buffer showing the previous answer instead of executing switch on.

Therefore to send a second ON I always must terminate Firefox first, f.e. by removing all apps from memory, and then the second ON icon touch will work.

What can I do to send the command to the Tasmota device even if there is already an answer page in cache?

ChatGPT suggested to add something like Date.now() to the URL to make the
call unique so that no cache copy can exist, but how can I add this into the icon's command line?
ChatGPT adviced me to create a new HTML file with JavaScript code in it, but while calling this file the command was executed properly it didn't work
when the HTML file was assigned to an icon via "add to start screen".

I simply want to touch the ON and OFF icons without having the need to
cancel Firefox first. How can I do that?

This doesn't look like Firefox problem.
Why don't you install a Tasmota control app on your phone?
A Quick search on my phone shows at least 3 available.

Yes, it's not a Firefox problem but a problem I want to solve using Firefox. And caching pages is a Firefox job.
Of course, I could run another browser - and probably would have the same problem.

Why don't you install a Tasmota control app on your phone?

Why should I start an additional app, select the device and toggle its state when I can do that with a single touch only?

Because you can't, you already tried that, the answer of your device
gets stuck in your browser, instead of an app which monitors its state.

step 1: click the shortcut
step 2 : tell the browser to refresh the webpage.

Your device sends you a status message, and Firefox can't handle that.
You can try Rudy's solution, but that was likely the first thing you tried.
If that doesn't work write yourself a web page (with a button!) which
acts as the app.
If you can't do that, stop whining and get the app.

My question was

Sure, it's not mainly a question for Firefox, but Firefox - and probably
other browsers too - buffers the answer page and does not send the request again.

My problem is not to send an URLor command using Firefox or any other app
but preventing Firefox from accessing its buffer instead of sending the request again. If any other app can do this, can Firefox do this also?

What a waste of time, is this your hobby?

I don't think this is a browser/cache problem, the device is trying to
talk to you and you are only shouting ON and OFF.
I doubt a device that's turned off would talk to me, so what does off
really mean here?
Is it stand-by? Is it sleeping? If so, how do we wake up the device?
Shouting ON doesn't wake it up, reconnecting the browser (phone?)
apparently does. Can we wake it up without reconnecting?

All of this (and more) is solved by the app, get the app.

Cheers, and good luck, I'm done with this now.

Try appending a time-stamp to the URL, led by a question

Getting this timer value needs a javascript function, but this can't be
called in the command line, and even ChatGPT could not serve with a few
lines html-code solution without additional dependencies. In Wndows I could construct such a command line even simply in .bat files, but AFAIK Android
has not such ones.

If by "incognito" you mean "private", I managed time ago to make my
Firefox open private windows by default in Android. I don't remember
how, I know I had to insist a few times till I got it done.

Are you sure that it's Firefox that's caching
the page? Web server caches pages as well.

You need to force the web server (e.g. Apache,
router firmware) to "forget" its cached pages
if you cannot do it from client side
(e.g. Firefox).

Did you really use the trick I suggested? Did
it work or not? Did you just wanna fool around
to troll honest programmers? :)

Are you also trying to create A.I. that
fools around? Well....

AND... AND....

If you could not do anything against the
firmware/web-server and Firefox was not
to be blamed, the only last solution is
to file a complaint against the firmware
comapny? :)

Tasmota does not cache anything at all - this runs on a tiny
microcontroller without much RAM. They can not afford to spend that
memory for caching.

Yes, but an ugly one as all old versions also stay in the cache and fill
it up. Better would be to send an appropriate headers in the HTTP response:

Cache-Control: no-store, no-cache, must-revalidate, max-age=0
Expires: 0

However, I don't think, that there is a configuration option for that,
you may have to patch the web server code of Tasmota to do this.

You don't infer from hardware spec. You have to test
things using tools like ncat to find out.

Maybe Wendelin Uez <wuez@online.de> should restart

I presume Android don't do strange things when

Anyway, the caching is either in the server or

most know.

How does ncat show you, if the *server* cached a page, before it was
sent to the client?

Also look at the code of Tasmota - there is no server side chaching.

Tasmota whenever he/she thought its caches was

No, this does not help, when the *browser* caches the result. That's the reason, why Tasmota has an API to access data and you usually control
devices not using Tasmota directly but with an MQTT broker like Home
Assistant.

I presume Android don't do strange things when
it comes to caching. And we don't know what

No, the same things happen in desktop browsers as well. When a webserver
does not send any headers which forbid caching, a website is *always*
cached.
