-# 🔥 V-Fire Monitor - Notifier Master (v1.0)
+# V-Fire Monitor
 
-O **V-Fire Monitor** é uma solução robusta de monitoramento e gestão para centrais de alarme de incêndio da linha **Notifier (NFS-320, NFS-640, NFS-3030)**. Desenvolvido para a **Voltec**, o software atua como um gateway inteligente entre o protocolo Modbus/TCP das placas BACNET-GW-3 e o sistema de monitoramento Zabbix, oferecendo uma interface web intuitiva e um sistema de licenciamento proprietário.
+Aplicacao Flask para monitoramento de centrais Notifier via Modbus/TCP, com painel web, descoberta de pontos, integracao com Zabbix e licenciamento por hardware.
 
----
+## O que mudou nesta refatoracao
 
-## 🚀 Funcionalidades Principais
+- Persistencia JSON com escrita atomica e migracao de configuracao legada.
+- Login com hash de senha em vez de senha em texto puro no arquivo de configuracao.
+- Chave secreta do Flask persistida localmente, sem valor fixo no codigo.
+- Validacao de payloads da API e respostas de erro consistentes.
+- Logging basico para diagnostico, no lugar de falhas silenciosas.
+- Polling Modbus e discovery por blocos, reduzindo chamadas individuais.
+- Frontend com tratamento de erro e textos corrigidos.
+- Gerador de licenca com argumentos de linha de comando e validacao de data.
 
-* **Monitoramento Multi-Node:** Gerenciamento de múltiplas centrais simultaneamente via IP/Modbus.
+## Estrutura
-* **Auto-Discovery Ultra:** Varredura automática de endereços Modbus (registradores 1-600) para identificação instantânea de dispositivos.
-* **Integração Nativa Zabbix:** * Envio de **LLD (Low Level Discovery)** para autocadastro de itens.
-    * Monitoramento de **Status de Evento** (Alarme, Normal, Removido).
-    * Monitoramento de **Integridade de Comunicação** (Link de dados do ponto).
-* **Gestão de Licenciamento:** * Proteção por **Hardware ID (HWID)** vinculada à máquina física.
-    * Controle de expiração por data com contador regressivo no painel.
-* **Persistência de Dados:** Nomes personalizados de sensores são preservados no banco de dados local (`.json`), mesmo após novos scans.
-* **Interface Web Profissional:** Painel em *Dark Mode* com indicadores visuais coloridos e status em tempo real.
 
----
+- `monitor.py`: entrypoint simples da aplicacao Flask.
+- `vfire_monitor/__init__.py`: app factory e bootstrap da aplicacao.
+- `vfire_monitor/core.py`: regras de negocio, persistencia, licenca e engine de monitoramento.
+- `vfire_monitor/routes.py`: rotas web e APIs.
+- `generator.py`: gerador de serial de licenca.
+- `templates/`: telas do login e dashboard.
+- `tests/`: suite inicial de testes automatizados.
+- `config_nodes.json`: configuracao persistida da aplicacao.
+- `mapa_dispositivos.json`: mapa de dispositivos descobertos.
+- `license.key`: serial instalado localmente.
+- `app_secret.key`: segredo de sessao gerado automaticamente na primeira execucao.
 
-## 📂 Estrutura do Projeto
+## Requisitos
 
-* `monitor.py`: Core do sistema. Gerencia o loop de leitura Modbus, o servidor Flask e o envio de métricas via Zabbix Sender.
+- Python 3.10+
-* `generator.py`: Ferramenta administrativa da Voltec para gerar seriais de ativação criptografados.
+- Conectividade com as centrais via Modbus/TCP
-* `templates/`:
+- Acesso ao servidor Zabbix, quando a integracao estiver habilitada
-    * `login.html`: Interface de autenticação segura.
-    * `index.html`: Dashboard principal com monitoramento de nós, sensores e licença.
-* `config_nodes.json`: Arquivo de persistência para IPs das centrais e endereços do servidor Zabbix.
-* `mapa_dispositivos.json`: Mapeamento detalhado de cada endereço Modbus e seu rótulo personalizado.
 
----
+Instalacao:
 
-## 🛠️ Instalação e Requisitos
-
-### Dependências Python
 ```bash
-pip install flask flask-login pyModbusTCP zabbix-utils cryptography
+pip install -r requirements.txt
+```
+
+## Variaveis de ambiente
+
+Veja `.env.example`.
+
+As principais:
+
+- `VFM_DEFAULT_PASSWORD`: senha inicial do usuario `admin` na primeira carga do sistema.
+- `VFM_APP_SECRET`: opcional, substitui o segredo salvo em `app_secret.key`.
+- `VFM_LICENSE_MASTER_KEY`: chave mestre do licenciamento. Em producao, use esta variavel e remova a dependencia da chave legada.
+- `VFM_ENV`: use `production` para obrigar `VFM_LICENSE_MASTER_KEY` no startup.
+- `VFM_LOG_LEVEL`: nivel de log, por exemplo `INFO` ou `DEBUG`.
+- `PORT`: porta HTTP da aplicacao.
+
+## Execucao
+
+```bash
+python monitor.py
+```
+
+O sistema sobe em `http://0.0.0.0:8080` por padrao.
+
+## Geracao de licenca
+
+Modo interativo:
+
+```bash
+python generator.py
+```
+
+Modo por argumentos:
+
+```bash
+python generator.py --hwid "UUID-DO-CLIENTE" --cliente "Cliente" --expira 2026-12-31
+```
+
+## Observacoes operacionais
+
+- A senha do painel fica armazenada como hash em `config_nodes.json`.
+- Se existir configuracao antiga com `web_password`, ela e migrada automaticamente para `web_password_hash`.
+- Em ambiente de desenvolvimento, o sistema ainda aceita a chave de licenca legada embutida para manter compatibilidade.
+- Em ambiente de producao (`VFM_ENV=production`), `VFM_LICENSE_MASTER_KEY` passa a ser obrigatoria e o sistema falha no startup sem ela.
+- Bootstrap continua sendo carregado via CDN. Se o ambiente nao tiver acesso externo, copie os assets localmente e ajuste os templates.
+
+## Testes
+
+Executar:
+
+```bash
+pytest
+```
+
+## Proximos passos recomendados
+
+- Adicionar testes cobrindo polling Modbus e integracao com Zabbix com doubles dedicados.
+- Separar configuracao e logging em modulos proprios se a aplicacao continuar crescendo.
+- Trocar Bootstrap via CDN por assets locais se o ambiente alvo nao tiver acesso externo.
