PLC 8 Relay Control (KMTronic)

About PLC 8 Relay Control (KMTronic)

Control your 8-channel KMTronic relay boards straight from your phone, on your local network. Rewritten from scratch as a native app: fast, modern and privacy-first.

FEATURES
• Switch the 8 relays on and off with a tap
• Status refreshes automatically, with a Connected/Disconnected indicator
• Manage multiple boards and find them instantly with search
• Add a board with its IP, port and optional credentials
• Relay names read straight from the board
• Light/Dark/System themes + a "Battery saver" theme for OLED/AMOLED screens
• Haptic feedback on tap and a two-pane landscape layout
• Italian and English

SECURITY & PRIVACY
• Boards and credentials encrypted on your device (AES-256, key protected by the phone's hardware)
• No account, no tracking: the developers receive no data
• Encrypted backup with your own password: manual export and automatic backup to your private Google Drive, handled by Android. Only you can decrypt it — not even we can

COMPATIBILITY
Works with 8-relay KMTronic LAN boards on your local network (Wi-Fi/LAN). The boards talk over HTTP: on public networks credentials travel unencrypted, so use a VPN or a trusted network (the app warns you when you enter a public IP).
