The Beurer OT20 basal thermometer cannot be automatically connected to the OVY app as it does not have a Bluetooth function. Here are the steps to manually transfer your readings to the OVY app:

- Take the temperature measurement with the OT20 basal thermometer and note the measured value.
- Open the OVY app on your smartphone.
- Enter manually: Enter the measured temperature value into the OVY app to document and track your cycle data.
