SMARTCLOTH. Design, Implementation and Study of the Effectiveness and Usability of a Digital Tablecloth for Self-management of Diet in Diabetic Patients.

The objective of this clinical trial is to know the usability and efficacy of SMARTCLOTH for better control and adherence to the dietary patterns recommended to patients with diabetes, both the portion diet system (more common for cases of Diabetes Mellitus type 1 -DM1-), and the plate method (more recommended in cases of Diabetes Mellitus type 2-DM2-). The main questions are: * Does the use of SMARTCLOTH improve glycemic control in patients with diabetes mellitus? * Do patients with diabetes mellitus find SMARTCLOTH useful in their daily lives? The researchers will compare changes over 3 months in variables related to glycemic control in two groups, one using SMARTCLOTH (intervention group) and the other following standard recommendations (control group). To do so, participants will have to: * Use SMARTCLOTH for 3 months or follow the recommendations they receive from their referring health professionals. * Come back after three months for a check-up of the chosen variables. * The experimental group should contact the investigators in case the hardware has any problems.
