Okay. I made a draft PR that changes the setValue of the service.
But I will make a call on the other channel 
@AlexTrovato
My Tuya sensor works very well, unlike my other Xiaomi sensor which disconnects from time to time and needs to be reset using its button, which is not acceptable for an alarm system.
I therefore opted for Tuya vibration sensors for monitoring my secondary residence, placed on all openings.
However, I would like to modify the trigger sensitivity, adjustable on 3 levels, low, medium and high.
Do you have the possibility to integrate this feature into this sensor?
Thank you
edit: I think I found the solution by going to the 8080 frontend page, the new sensitivity is updated after a new trigger: this suits me for now.
Yes indeed, to configure the sensitivity of devices or calibrate them, it is recommended to use the zigbee2mqtt tool, and not Gladys.
