ser2netweb

Serial-to-network bridge with a web UI: share local serial ports (RS-232 / RS-485, USB adapters) over the network as raw TCP, telnet, RFC 2217 or UDP, run a Modbus RTU/TCP gateway, publish serial data and Modbus points to MQTT and Sparkplug B, all set up and watched in a browser, with accounts, roles, an audit log, TLS and LDAP / OpenID Connect sign-in.

ser2netweb (named ser2net up to 2.9.x) is an independent Python project. It is not related to or derived from Corey Minyard's ser2net daemon (github.com/cminyard/ser2net), whose classic configuration files it can import.

Install

pipx install ser2netweb              # or: pipx install "ser2netweb[all]"
ser2netweb                           # asks for the web UI's address on the console, then serves it

Python 3.10 or newer on Linux, macOS or Windows. The extras add the optional features: mqtt (paho-mqtt), ldap (ldap3), oidc (authlib), tls (cryptography: self-signed certificates in-process), all (every one); later: pipx inject ser2netweb paho-mqtt. On Linux, opening a serial port needs membership in its group (dialout on Debian, Ubuntu, Fedora; uucp on Arch).

A pip / pipx install keeps its data (config.json, backups, logs, traces) in the user's data folder, never next to the package:

OS Data folder
Linux and other Unix $XDG_DATA_HOME/ser2netweb, else ~/.local/share/ser2netweb
macOS ~/Library/Application Support/ser2netweb
Windows %LOCALAPPDATA%\ser2netweb

--data-dir DIR (or --config FILE) chooses another folder. ser2netweb --help lists the options, ser2netweb --about shows the versions and where each component is loaded from.

To run it as a service (systemd, the Windows service), use the standalone executables or the .deb / .rpm packages of a release instead: they come with a hardened systemd unit and --install-service. Docker: ghcr.io/haliskilic/ser2netweb.
