Firmware IAMMETER i.91.065.17: recuperação segura, Swagger API e suporte WEM3063T
Esta versão amplia a série i.91.065 com recuperação de palavras-passe esquecidas, testes de API no navegador e suporte ao novo 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:
Recuperação segura da palavra-passe Admin
Se esquecer a palavra-passe Admin Security, pode confirmar que o dispositivo está associado à sua conta IAMMETER e recuperar o acesso local sem ligação ou reposição direta pelo 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.
Suporte WEM3063T para o mercado dos EUA
O WEM3063T é um contador trifásico desenvolvido para os EUA, com CTs externos de saída padrão de 5 A. Passou por testes de produto e segurança no processo UL em curso, incluindo testes SGS.

Before upgrading, confirm the model, CT and regional requirements.
Testes Swagger API com Basic Auth
Ferramentas no navegador podem chamar APIs protegidas com HTTP Basic Authentication; o CORS permite agora o cabeçalho 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.
Outras melhorias de segurança
The Security page now provides a clearer Enable/Disable Security Module link to the Local Admin Security User Guide.
Verificação de certificados MQTTS e HTTPS
A série i.91.065 suporta builtin, custom e none; none é indicado apenas para compatibilidade ou testes controlados. Consulte o guia 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.
Correções e fiabilidade
- 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.
