2021-01-05· As a next step for the SCD30 it tries immediately a readMeasurement(), if no data is available it will return false and the OLA will assume that 0x61-device is not SCD30. I expect this readMeasurement() to fail as the SCD30 is set in begin() to perform a measurement every 2 seconds, so NO data available immediately.
