Aggiornamento firmware IAMMETER i.91.065.17: recupero Admin sicuro, Swagger API e supporto WEM3063T
Firmware IAMMETER i.91.065.17 si basa sulla serie i.91.065 e aggiunge recupero delle credenziali dimenticate, test API nel browser e supporto al nuovo contatore 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:
Recupero sicuro della password Admin
Se dimentichi la password Admin Security, verifica che il dispositivo sia associato al tuo account IAMMETER e recupera l’accesso locale senza connessioni o reset diretti da IAMMETER Cloud.
- 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.
Supporto WEM3063T per il mercato statunitense
Il WEM3063T è un contatore trifase sviluppato per il mercato USA, con TA esterni a uscita standard 5 A. Ha svolto test di prodotto e sicurezza nel processo UL in corso, inclusi test SGS.

Before upgrading, confirm the model, CT and regional requirements.
Test Swagger API con Basic Auth
Gli strumenti browser come IAMMETER WEM API Test possono chiamare API protette con HTTP Basic Authentication; CORS consente l’header 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.
Altri miglioramenti di sicurezza
The Security page now provides a clearer Enable/Disable Security Module link to the Local Admin Security User Guide.
Verifica certificati MQTTS e HTTPS
La serie i.91.065 supporta builtin, custom e none; quest’ultima modalità è adatta solo a compatibilità o test controllati. I dettagli sono nella guida MQTTS e 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.
Correzioni e affidabilità
- Strengthened OTA structure and integrity checks.
- OTA errors return precise JSON and do not restart the meter.
- Improved Web UI network-error and timeout handling.
- Fixed OTA responses when Admin Security is enabled.
- Improved POST handling across multiple TCP packets.
- Fixed the OTA result page.
- Fixed reactive-power scaling for WEM3046T/WEM3063T.
- Added WEM3063T Wi-Fi LED logic.
