KD DFU vs SMSNode

A utility to do the door lock firmware upgrade

SMSNode is a cross-platform client for managing hardware SMS gateways and SIM cards through a convenient, modern chat interface. Key Features: Unified Chat Interface: send and receive SMS through your gateways as easily as in a regular messenger. Contact Management: organize your address book, create groups, and manage conversations efficiently. SIM & Gateway Control: monitor your GSM equipment (GoIP and others) directly from your device. Admin Tools: manage user permissions, gateway status, and routing rules on the go. Modern Design: full Material 3 support and dark mode. IMPORTANT: This is a client-side app. It REQUIRES a self-hosted SMSNodeBackend server. Without your own server, the app runs in Demo Mode only, letting you explore the interface on our test environment. Lawful use only. You are solely responsible for the connected equipment, SIM cards, and the content and legality of the messages you send, including obtaining recipients' consent. Any unlawful use — spam, fraud, or caller-ID spoofing — is prohibited. Perfect for privacy-conscious individuals and businesses who want full control over their SMS communication and hardware.
