@diegogmx <https://github.com/diegogmx> sinceramente nosé de lo que me hablas....y no, no soy electrónico. Lo que tengo implementado es obtener datos con arduino, transmitir por mqtt a una raspberry y ahi con python/django hacer todo lo de transmitir los datos a un server central, almacenar datos y mostrar en gráficos la data — Reply to this email directly, view it on GitHub <#85 (comment)>, or unsubscribe <https://github.com/notifications/unsubscribe-auth/ABGCAQSCWSJQBFAIHZ3AYADU47DUTANCNFSM5NQVAG2Q> .
