  1. #Reticulum excels at off-grid communication, but sensor readings run on a different packet economy to chat.

    A Reticulum Link costs three packets and 297 bytes to establish. For an isolated reading every 10 minutes, LXMF opportunistic delivery embeds data in a single packet (<255 bytes), skipping handshake overhead and radio fragmentation.

    Propagation Nodes give duty-cycled nodes encrypted store-and-forward.

    Part one of three.

  2. Sensor Data Over Reticulum: LXMF, Propagation Nodes, and the Low-Power Case

    LPWAN Meshes: Reticulum, Where I Landed covered Reticulum as a communications stack: transport-agnostic, cryptographically addressed, built for chat and file transfer over LoRa, packet radio, or whatever medium is available. This post is narrower on purpose: it breaks down the specific mechanics of moving a sensor reading, not a conversation, through Reticulum: which delivery method to pick, what a reading actually costs in packets and bits per second, and what already exists in the open-source community to build on rather than reinvent.

  3. Off-grid comms has always forced a choice: sub-GHz bands for range, or compromise for throughput. 2.4 GHz LoRa is breaking that trade-off open.

    GrayHatGuy has proven MeshCore runs on 2.4 GHz — and built the bridges that connect it back to sub-GHz backbones when you need the long hop.

    New post: protocol bridges, channel bridges, frequency bridges, and why the difference matters.

  4. After years of hands-on testing — from early Meshtastic nodes to running Reticulum across remote South Australian properties — I've learned that choosing off-grid mesh networking technology isn't purely technical. It's philosophical. LPWAN series: a detailed, honest comparison of Meshtastic, MeshCore, Reticulum, and ClusterDuck Protocol, born from failed experiments and the occasional moment of genuine excitement when a packet hops across several kilometres of Australian bush.

  5. LPWAN Meshes: ClusterDuck Protocol - Purpose-Built for Emergencies

    The ClusterDuck Protocol (CDP) was where my mesh networking journey truly began. The story behind Project OWL (Organisation, Whereabouts, and Logistics)—students building emergency communication networks after Hurricane Maria—resonated deeply, highlighting a technology designed not for hobbyists or industry, but for saving lives when infrastructure fails. While I found its concepts “much better thought through” from the outset, the project’s slow pace and patchy hardware support meant my personal involvement never truly moved beyond some initial tinkering.

    I'm using #LoRaWAN and #Tasmota for sensors on

    - energy metering
    - water metering
    - level monitoring on oil and rain water tanks
    - smoke detectors
    - climate monitoring
    - window/door monitoring
    - charging control for electric cars
    - light control
    - tracking of my ebike
    ...

    Lots of fun with #LPWAN 😋 but conversation on #Meshtastic seems to be pretty limited to ham level (cq, qsl, hello?, qth, ...)

    my #Meshtastic node is high on a mast with up to 25km LOS but not really exciting

  7. Как создать простой LoRa мессенджер: обмен текстовыми сообщениями между устройствами без интернета

    В современном мире IoT, когда связь в отдаленных районах становится все более актуальной, технология LoRa (Long Range) предоставляет нам возможность создать дальнобойный, надежный, энергоэффективный и зашифрованный канал связи без необходимости иметь какую-либо сетевую инфраструктуру. В этой статье мы рассмотрим, как создать простой LoRa мессенджер с использованием своего протокола обмена и готовых модулей, работающих в режиме P2P (peer-to-peer) – не идеального, но интересного решения для обмена текстовыми сообщениями в условиях ограниченной инфраструктуры. Для упрощения и автоматизации процесса обмена сообщениями мы воспользуемся Node-RED. Этот инструмент, помимо реализации основной логики обмена сообщениями, также предоставит графический интерфейс для мессенджера, что сделает процесс более доступным и интуитивно понятным. Выглядеть будет просто, потому что воспользуемся всем готовым :) Свистать всех наверх!

  8. I have just published the first version of my #CayenneLPP (low power payload) #Rust #crate. There is still some stuff to do (better documentation, examples, ...), but it was already a good training for me to write a "no_std" crate 🙂. #iot #lorawan #ttn #lpwan #payload crates.io/crates/cayenne_lpp

  9. Not sure how reproducible this is over water. Would highly depend on the weather conditions, I guess. I personally would stick with the one that TTN did over Europe with a high-altitude balloon.

    Not really relevant to the real-world distances for sensors, but still interesting to show the possibilities. #lorawan #iot #wireless #lpwan
