IoT devices for Meschtastic can be flashed to use Mesh Node access by Reticulum gateway to wifi thru the internet.
NOTE: Content here are my personal opinions, and not intended to represent any employer (past or present). “PROTIP:” here highlight information I haven’t seen elsewhere on the internet because it is hard-won, little-know but significant facts based on my personal research and experience.
Although the internet being down may be unimaginable, it does happen.
LoRa was designed to operate over long distances at extremely low bandwidth power, ith very high latency.
Coverage can be wide when there are enough Repeaters which forward messages between Rnodes.
Text messaging without the Internet.

Meshtastic (at meshtastic.org) created open-sourced firmware as a volunteer community. The firmware is flashed onto off-the-shelf LoRa radio hardware, creating a mesh communication network.
MeshCore competes with Meshtastic.
Reticulum is a Python module which runs in a Raspberry Pi or ESP32 board with radio chips that transmit LoRA messages. Reticulum was created by Mark Qvist (LXMF at 8dd57a738226809646089335a6b03695)
QUESTION: Run on Mac Mini?
Conceptually, Reticulum runs on top of Meshtastic, Mesh Core, and WiFi, thus bridging the techologies and provides a gateway to the regular wide-area internet.
Reticulum wraps its packets into Meshtastic messages, sends them over LoRa, then unwraps them back into Reticulum on the other side.
REMEMBER: Reticulum does not use IP addresses and ports known from IP, TCP and UDP. Reticulum packets transmitted do not include information about where they originated from.
This enables destination identities to be “self soverign” rather than assigned by a central bureaucracy. Thus, Reticulum are networks without kill-switches, surveillance, censorship and control: networks that can freely interoperate, associate and disassociate with each other.
Reticulumi recognizes each destination apps that use Reticulum to receive data as a 16-byte hash derived from cryptographic identity characteristics.
All communication is secured with strong, modern encryption by default. BLOG: Reticulum is a cryptography-based networking stack offering end-to-end encryption (using Ed25519 Signatures), initiator anonymity, autoconfiguring cryptographically backed multi-hop transport, and unforgeable delivery acknowledgements.

uses the peer-to-peer and distributed messaging system LXMF (Lightweight Extensible Message Format) defined at https://github.com/markqvist/lxmf There is no sign-up, no service providers, no “end-user license agreements”, no data theft and no surveillance. You own the system.
Each LXMF message is identified by its message-id constructed from a SHA-256 hash of the Destination, Source and Payload.

MakerHawk $34.99 Heltec $35.99 Waveshare Raspberry Pi LoRa HAT based on SX1262, covers 915MHz frequency band antenna. It allows data transmission up to 5km through serial port. Its standard Raspberry Pi 40PIN GPIO extension header supports Raspberry Pi series boards Onboard CP2102 USB TO UART converter, for serial debugging Brings the UART control interface, for connecting host boards like Arduino/STM32. It has 4x LED indicators to check the module status LoRa spread spectrum modulation technology, up to 81 available signal channel, longer communication distance, more robust to interference Auto multi-level repeating, suit for ultra long range communication, allows multi network on the same region
uv add rnspure
Option B: The ‘rns package requests dependency downloads dynamically:
uv add rns # = pip install
~/.reticulum/config (to learn from):
bashrnsd --exampleconfig
The default configuration provides basic connectivity to other locally reachable Reticulum peers. Example:
ini[reticulum]
enable_transport = No
[interfaces]
[[AutoInterface]]
type = AutoInterface
enabled = yes
ini[[RNS Testnet billings]]
type = TCPClientInterface
enabled = yes
target_host = billings.connect.reticulum.network
target_port = 4965
ini[[RNode LoRa]]
type = RNodeInterface
enabled = yes
port = /dev/ttyUSB0
frequency = 868000000
bandwidth = 125000
txpower = 7
spreadingfactor = 8
codingrate = 5
rnsd -d # run as daemon (background)
rnsd # run in foreground
This locks the CLI window.
