Der er godt gang i Open Source LoRa-fællesskabet rundt om i verden. Seeedstudio har skrevet en fed artikel om forskellene mellem Meshtastic og Meshcore, der måske kan hjælpe dig med at vælge, hvis du overvejer at købe.

TIL That the nice looking slim #SenseCAP Card Tracker T1000-E has two variants, #MeshTastic and #LoraWan - the only difference is that the LoraWan variant is Open Source. So Bigly Open Source in fact, that it has a locked bootloader preventing it from being used with MeshTastic.
In other news, if anyone needs a non-MeshTastic capable LoraWan T1000-E, feel free to ping me...
15°C and sun last week → snow in the lowlands today. March, everyone.
These transition weeks are when road ice gets most dangerous — right when people stop expecting it.
The DL-CWS2 measures road surface temp, humidity & dew point continuously. Battery-powered, weatherproof, years of maintenance-free operation. 100+ units deployed across Zurich for real-time ice warnings.
Floods, droughts, leaks — are you measuring from the right direction? 💧
From above: radar, ultrasonic, laser sensors mounted over the surface. No contact with the water.
From below: pressure sensors lowered into tanks, groundwater, boreholes.
All battery-powered, all wireless via LoRaWAN. No cabling — even in the most remote locations.

8-inch ESP32-P4 touch display offers WiFi 6, BLE, 802.15.4 connectivity, optional 4G LTE and LoRaWAN
Seeed Studio's reTerminal D1001 is an 8-inch capacitive touch display powered by an ESP32-P4 RISC-V microcontroller and equipped with an ESP32-C6 wireless module, a camera, a dual-microphone array, and a speaker. The reTerminal D1001 is a fully enclosed solution designed for HMI applications such as control panels, vision-enabled IoT terminals, video intercoms, and smart dashboards. One highlight compared to other ESP32-P4 displays is optional support for 4G LTE cellular connectivity using an mPCIe module and SIM card slot, as well as LoRaWAN using a Stamp module. reTerminal D1001 specifications: SoC – Espressif Systems ESP32-P4NRW32 CPU Dual-core 32-bit RISC-V HP (High-performance) CPU @ up to 400 MHz with AI instructions extension and single-precision FPU Single-RISC-V LP (Low-power) MCU core @ up to 40 MHz Memory 768 KB HP L2MEM (for dual-core CPU), 32 KB LP SRAM, 8 KB TCM (for LP MCU core) 32MB PSRAM Storage – 128 KB HP ROM, 16
Can you guess what's hiding inside? 👀
It's the DL-LID — our laser distance sensor for LoRaWAN®, now available in a brand new weather protection housing and so easy to mount.
Up to 40 m range, 1 mm resolution, battery-powered — reporting back wirelessly through LoRaWAN.
Perfect for:
🔹 Snow level tracking
🔹 Water level & flood monitoring
🔹 Generic ranging
Set it up. Walk away. Let it do the distance measurement and send data to you.

Hello,
Je regarde pour monter un point #lorawan chez moi, et utiliser du #lora à titre perso + relais. Mais je veux pas aller m'enfermer et j'aimerais coupler cela à mon #Homeassistant full #zwave
Un conseil en terme de matos ? du #MS48-LR - #LPS8v2 ? sur du Hat #RPI genre #SX1302 ? autre(s)?
L'idée serait de balancer une sonde dans une cuve pour télémétrie, avoir un second protocole pour la détection extérieur, station météo (coupler à HA + pilotage chauffage/eau chaude), etc :)
Merci
Most people think Bluetooth works at about 10 meters.But researchers have already demonstrated Bluetooth attacks 𝗳𝗿𝗼𝗺 𝗺𝗼𝗿𝗲 𝘁𝗵𝗮𝗻 𝗮 𝗺𝗶𝗹𝗲 𝗮𝘄𝗮𝘆 using directional antennas and external power amplifiers.
Now a company called Hubble Network has demonstrated Bluetooth connectivity 𝗮𝗹𝗹 𝘁𝗵𝗲 𝘄𝗮𝘆 𝘁𝗼 𝘀𝗮𝘁𝗲𝗹𝗹𝗶𝘁𝗲𝘀 using space-based phased-array receivers. And they’re building and launching the constellation.
What if you could see what's happening beneath your crops in real time?
A quick guide to picking the right soil sensor:
🔹 DL-TRS12 — Moisture, temp & conductivity. All-rounder for any soil.
🔹 DL-TRS21 — Water potential. What the plant actually feels.
🔹 DL-SMTP — Depth profile. Follow water to the roots.
🔹 DL-SDD — Moisture + salinity. Soil health & nutrients.
