The goal of this clinical study is to validate C-mo System's ability to automatically detect and characterise cough, in patients over 2 years old with cough as a key or refractory symptom. The main questions it aims to answer are: 1. Can C-mo System detect cough events? (automatic cough detection) 2. Can C-mo System characterise cough events? (calculation of cough intensity, identification of cough type and presence of wheeze in detected coughs) Participants will be asked to: * Wear the C-mo Wearable device for 24 hours (1 day); * Complete a diary with relevant activities throughout the monitoring period; * Fill-out questionnaires related to coughing frequency and intensity, usability of the device, and impact of cough on quality of life.
