Tuya temperature/humidity sensor (TS0601) getting incorrect readings

I recently bought a Tuya TS0601 (_TZE200_a8sdabtg) from AliExpress and periodically (~every 15 minutes) I am getting weird/incorrect readings. Specifically the temperature will drop to 32 degrees Fahrenheit and the humidity will jump to 655.4%. When the sensor is not reporting 32 degrees/655.4% humidity the readings appear to be correct.

Here is a graph showing some of the incorrect readings:

And here is the device signature:

{
  "node_descriptor": "NodeDescriptor(logical_type=<LogicalType.EndDevice: 2>, complex_descriptor_available=0, user_descriptor_available=0, reserved=0, aps_flags=0, frequency_band=<FrequencyBand.Freq2400MHz: 8>, mac_capability_flags=<MACCapabilityFlags.AllocateAddress: 128>, manufacturer_code=4742, maximum_buffer_size=66, maximum_incoming_transfer_size=66, server_mask=10752, maximum_outgoing_transfer_size=66, descriptor_capability_field=<DescriptorCapability.NONE: 0>, *allocate_address=True, *is_alternate_pan_coordinator=False, *is_coordinator=False, *is_end_device=True, *is_full_function_device=False, *is_mains_powered=False, *is_receiver_on_when_idle=False, *is_router=False, *is_security_capable=False)",
  "endpoints": {
    "1": {
      "profile_id": "0x0104",
      "device_type": "0x0302",
      "input_clusters": [
        "0x0000",
        "0x0001",
        "0x0003",
        "0x0402",
        "0x0405"
      ],
      "output_clusters": [
        "0x0003"
      ]
    }
  },
  "manufacturer": "",
  "model": "TS0601",
  "class": "zigpy.device.Device"
}

Iā€™m curious if anyone else has experience with something like this or has any tips for debugging

Got today the same sort of this devices _TZE200_a8sdabtg . Two pieces and the same behavior as yours.
But no idea. I will let them run through the night to get more measurements about that dropouts.

At the first time I used the reset knob and the values of the thermometers were ok. Up to now I know, that the device turns back to normal measurement by itself.

Help appreciated, thanks.

Problem solution for me:

  • Delete the device Home Assistant.
  • Reset the device with the little pin.
  • Pair the device again with HA.
    Since 1 day exact results in temperature and humidity.

Good luck.
