| 32 | ## 🔒 Nota sobre certificado SSL |
| 33 | |
| 34 | BYMA presenta un certificado SSL cuya CA intermedia no esta incluida en |
| 35 | el bundle `certifi` estandar de Python. Esto causa: |
| 36 | |
| 37 | ``` |
| 38 | SSLError: CERTIFICATE_VERIFY_FAILED |
| 39 | ``` |
| 40 | |
| 41 | **El script usa `verify=False`** — la conexion sigue siendo TLS-encriptada |
| 42 | pero se omite la validacion de cadena. Es el patron estandar de las |
| 43 | librerias publicas de BYMA (`pyhomebroker`, `bymadata`, etc.). |
| 44 | |
| 45 | Si preferis no usar `verify=False`, podes instalar el cert intermedio de |
| 46 | BYMA en tu trust store del sistema. |
