Please consider adding support for the TEMPerX232 1a86:5523TEMPerX232_V2.0 Temperature & Humidity USB sensor.
This may add another dependency, pyserial, seeing as ccwienk/temper could only get it working via UART (see below).

White plastic USB stick marked "TEMPerX232", "0-100%RH", and "-40 - +85C"; with a green button marked "press". On the reverse, "PCsensor". On the end opposite the USB connector, there is a jack for an external temperature sensor (which I do not have and did not try).
When the button is pressed and held down until the red LED is solid, a blue LED will flash every second. In this mode, the USB vendor:product changes to 413d:2107, but only one HID device is available, and protocol sent to the hidraw device is rejected with an error.
When the LED is flashing blue, and the button is pressed momentarily, the following are sent (the temperature line repeats every second).
When the button is pressed and held down until the red LED is solid, a green LED will flash every second. This is the mode temper.py uses. In this mode, if "Help" is sent to the serial device, the following will be sent back:

Welcome to use TEMPerX232!
Firmware Version:TEMPerX232_V2.0
The command is:
ReadTemp -->read temperature,temp_value = sensor_value + calibration
ReadCalib -->read calibration
SetCalib-type:xx.x,xx.x> -->set calibration, xx.x(-10.0~+10.0)
EraseFlash -->erase calibration
Version -->read firmware version
ReadType -->read the sensor type
ReadAlert-Temp -->read temp alert value
SetTempUpperAlert-type:xx.xx>-->set temp upper alert value,xx.xx(-40.00~+85.00)
SetTempLowerAlert-type:xx.xx>-->set temp lower alert value,xx.xx(-40.00~+85.00)
ReadAlert-Hum -->read hum alert value
SetHumUpperAlert-type:xx.xx> -->set hum upper alert value,xx.xx(00.00~99.99)
SetHumLowerAlert-type:xx.xx> -->set hum lower alert value,xx.xx(00.00~99.99)
SetMode-Temp:x> -->set tempmode, x(0~1)
ReadMode-Temp -->read tempmode
Help -->command help
? -->command help
The COM configuration is:
Mode: ASCII
Baud Rate: 9600bps
Data Bit: 8
Parity Bit: None
Stop Bit: 1

This is the mode that temper.py uses. I was not successful getting this device to respond to any commands sent via the HID device.
I initially had trouble getting a reply to ReadTemp when using a terminal program (e.g., cu), but the example in the temper.py works without any problems, perhaps because no newline is sent after the command.

Adding support for these devices would close issues downstream - https://github.com/home-assistant/core/issues/105544 I have two of these devices plugged in, please let me know what I may do to help.
