    Necesito hacer un software para instalar en Linux, con interfaz web. La idea es que el software pueda recopilar datos de diferentes fuentes, MySQL, InfluxDB, MQTT, ModbusTCP, Ethernet/IP, OPCua, etc. Y poder crear alarmas con esos datos, reportes, e incluso interacciones (tipo Scada). Tambien deveríamos poder guardar los datos necesarios en una base de datos, MySQL o InfluxDB. La idea es qeu todo esto sea configurable desde la interfaz web. Necesito solo personal de habla en Español.
