Firmware IAMMETER i.91.065.17: recuperación segura, Swagger API y soporte WEM3063T
Esta versión amplía la serie i.91.065 con recuperación de contraseñas olvidadas, pruebas API desde el navegador y soporte para el nuevo contador WEM3063T.
This release is part of IAMMETER’s ongoing work to address the cybersecurity requirements applicable to internet-connected radio equipment under EN 18031-1:2024. Compliance and certification status for individual models will be announced separately when formally available.
Основные изменения:
Recuperación segura de la contraseña Admin
Si olvidas tu contraseña Admin Security, puedes verificar que el dispositivo está asociado a tu cuenta IAMMETER y recuperar el acceso local sin que IAMMETER Cloud se conecte o reinicie el contador.
- Request a one-time recovery challenge from the device.
- Sign in to the IAMMETER Contributor system with your IAMMETER Cloud account.
- Submit the payload; the service verifies the device association.
- Receive a cryptographic Ed25519 signature.
- Send the signed request to the meter’s local IP address.
- After verification, Admin Security is disabled so new credentials can be configured.
The payload is bound to the serial number, MAC address and one-time nonce. The firmware contains only the public verification key; the service signs the challenge and does not connect to the meter directly.
See the IAMMETER Admin Password Recovery guide.
Soporte WEM3063T para el mercado estadounidense
El WEM3063T es un contador trifásico desarrollado para EE. UU., con TC externos de salida estándar de 5 A. Ha realizado pruebas de producto y seguridad dentro del proceso UL en curso, incluidas pruebas de SGS.

Before upgrading, confirm the model, CT and regional requirements.
Pruebas Swagger API con Basic Auth
Las herramientas del navegador pueden llamar a APIs protegidas con HTTP Basic Authentication; CORS permite ahora la cabecera Authorization.
- a browser that can reach the meter’s local IP
- valid Basic Auth credentials
- an API operation supported by the firmware
The request path is direct:
Browser → loads Swagger UI from iammeter.github.io
Browser → sends an authenticated request directly to the meter’s local IP
The Swagger website is not a server that connects to the meter. The browser must reach the device on the local network; protected requests still require Basic Auth.
Otras mejoras de seguridad
The Security page now provides a clearer Enable/Disable Security Module link to the Local Admin Security User Guide.
Verificación de certificados MQTTS y HTTPS
La serie i.91.065 admite builtin, custom y none; none solo se recomienda para compatibilidad o pruebas controladas. Consulta la guía MQTTS y HTTPS.
Upgrade and compatibility notes
Basic Auth remains required, existing OTA checks stay in place, and TLS and recovery-signature behavior are unchanged. Check the model on IAMMETER Firmware Updates.
