The weekly IoT digest

Every week, the Internet of Things stories that matter, summarized and put in context: platforms, connectivity, chips, security, regulation and AIoT. Published every Tuesday here and in the newsletter. RSS.

Issue 3 Week of October 5, 2026

Agents reach the factory floor, OPC UA over MQTT, and the quiet death of 2G and 3G

Issue 3: what AI agents can and cannot do with industrial equipment, why OPC UA's pub-sub profile matters, and what network sunsets mean for deployed fleets.

  • Vendors are shipping LLM-based agents that read machine data and propose actions; the ones that work keep a human or a PLC between the model and the actuator.
  • OPC UA PubSub over MQTT is becoming the default way to get factory data to the cloud without a custom gateway per machine.
  • 2G and 3G sunsets continue country by country; fleets on old modems need a migration plan, not a hope.
  • Digital twins are being rebuilt around event streams rather than CAD models, which makes them cheaper and more useful.

Issue 2 Week of September 28, 2026

Edge AI chips multiply, LoRaWAN goes to orbit, and the Cyber Trust Mark looks for buyers

Issue 2: why every microcontroller vendor now ships a neural accelerator, what satellite LoRaWAN is good for, and whether a U.S. security label changes purchasing.

  • Neural accelerators are becoming standard in mid-range microcontrollers, which changes what 'low power' inference means.
  • Satellite backhaul for LoRaWAN and NB-IoT is moving from demos to commercial plans for agriculture, shipping and utilities.
  • The U.S. Cyber Trust Mark is voluntary; its effect depends on whether retailers and procurement teams ask for it.

Matter settles in, the Cyber Resilience Act clock is running, and RedCap finds its niche

Launch issue of the weekly digest: where the smart home standard stands, what the EU's device security law means for makers, and why 5G RedCap matters for IoT.

  • Matter has moved from launch hype to steady releases; the interesting work is now in multi-admin, energy management and the slow arrival of cameras.
  • The EU Cyber Resilience Act applies to almost every connected product sold in Europe; reporting obligations arrive before the full conformity requirements.
  • 5G RedCap is settling into the mid-tier gap between LTE-M and full 5G, aimed at wearables, cameras and industrial sensors.
