Support for TEMPerGold (3553:a001)

[BeyondAeon]

Hi I've Picked up 3 Temper sensors & Tried to get them working.
I've added the USB ID to the devices
It Detects the Device and then Raises A Timeout and Dies.
I'm not great with Python or USB Protocol, But I have a Wireshark USB cap of the windows Software talking to the device.

I can provide the capture if it would help....

Thanks @BeyondAeon!

Please can you

1. summarise the code you added when you tried
2. Run the cli with -v and copy & paste the output
3. Attach the capture file when you have it working in windows
4. Tell us the real world reading that windows reported so we can spot them in the USB traffic

Thanks for contributing!

Hi, The cli.py doesn't work for me, gives me a error,
"import TemperHandler
ImportError: attempted relative import with no known parent package"
(I'm a python newb still)

added
"TEMPerGold": TemperConfig(
temp_sens_offsets=[2, 4],
hum_sens_offsets=None,
type=TemperType.FM75,
),
to device_library.py

added (0x3553, 0xa001), to VIDPIDS in temper.py

Attached zip file with Windows wireshark USB capture and screenshot of windows program.

I have a new TEMPer2 (also 3553:a001) and I get the exact same issue.

(myenv) pi@raspberrypi-stove-v2:~/temper-python $ lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 004: ID 3553:a001 PCsensor TEMPer2
Bus 001 Device 002: ID 2109:3431 VIA Labs, Inc. Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

I have also made the changes:

added (0x3553, 0xa001) to VIDPIDS in temper.py
added the following to DEVICE_LIBRARY in device_library.py
"TEMPer2": TemperConfig(
temp_sens_offsets=[2, 4],
hum_sens_offsets=None,
type=TemperType.FM75,
),

After these changes it finds the device but it fails to read the data. Here the output from temperusb.cli:

(myenv) pi@raspberrypi-stove-v2:~/temper-python $ sudo /home/pi/myenv/bin/python -m temperusb.cli -v

Any help much appreciated :)

P.S.2: Solved by returning the device.
