Go in the device, under advanced,
you will have a device_file field. Change it to: D_TemperatureSensor1.xml
in the device_json field paste: D_TemperatureSensor1.json
Sub Category_num_: 0
This will be for your temperature sensor.
You have a typo in what you posted so if you posted them as is, the files don't exist so the device will disappear. If the vera finds the file, as long as it exists, even if it is the wrong one, the device should not disappear.
