Alexa virtual devices

[hase-00]

Hello everyone,
I use Home Assistant with the "Matter Hub" add-on to control various devices (heating, lights, etc.) or to check their status. In the bathroom, I have a motion sensor that turns off the light when no movement is detected after a certain period. After adjusting various parameters, this works very well.
BUT: When someone relaxes in the bathtub, the motion sensor doesn't detect any movement, and the light turns off. To solve this problem, I can deactivate the timer by long-pressing the light switch. But you have to remember to do this BEFORE getting into the tub.
Of course, I can turn the light back on via Alexa ("Alexa, turn on the light"), but it then turns off again after the timeout without movement detection. That’s annoying.
I'm looking for a solution to deactivate the timer via Alexa, for example, by saying "Alexa, turn off the light timer." I am currently trying to set a system variable with a virtual switch using Alexa, but I haven't made progress yet.

Does anyone have an idea?

You could make a script or automation in home assistant to turn off the light timer.
Then expose the script to alexa. You'll get a "on-off" switch in Alexa (which is always off and can be turned on via voice -> this will trigger the script / automation).

Of course you do not want to say Alexa, turn on 'Deactivate Light Timer', so you could create a routine in Alexa called Turn off the Light Timer which then turns the script-switch on.
