Ship the project, not the plumbing.

Practical, tested walk-throughs for getting hardware talking to the cloud — real Arduino code, the bits other tutorials skip (like getting commands back to the device), and the battery tricks that make a sensor last months.

Control your ESP32 with Claude: an MCP server for your own hardware

Point Claude at your own IoT backend and let it read your sensors and flip your relays in plain language — no cloud middleman, no vendor skill. nodrix ships a native MCP server, owner-gated and off by default, that turns your ESP32 fleet into tools an AI agent can call.

The best free IoT platforms for makers in 2026, ranked

Every 'free' IoT platform caps something — devices, messages, retention, or all three. Here's an honest ranking of the free tiers makers actually use in 2026, what each one caps, and the one option where the free tier is Cloudflare's, not a vendor's.

ESP32-C3 vs ESP8266: the upgrade question, answered honestly

ESP32 vs ESP8266 in 2026, at the budget end: the ESP32-C3 is the 8266's designated successor at nearly the same price, with the RAM headroom that makes TLS comfortable instead of a squeeze. When to switch, when the old board is still the right call, where the wider ESP32 family fits, and what changes in firmware.

ESP32-C6 for makers: what the new radios change, and what they don't

The ESP32-C6 packs Wi-Fi 6, BLE, and an 802.15.4 radio for Thread and Zigbee into a $5 board — the ESP32 line's ticket into Matter. Here's what that actually means for a maker project today, the radio fine print nobody leads with, and why your cloud firmware doesn't change at all.

MQTT vs HTTP for IoT: an honest comparison for makers

Most MQTT-vs-HTTP comparisons are written by broker vendors, and it shows. Here's the maker's version: where MQTT genuinely wins, where the famous overhead numbers mislead, why WebSocket is the missing third option, and how to actually choose for an ESP32-class project.

nodrix vs Grafana + InfluxDB: the DIY IoT stack, weighed honestly

Grafana with InfluxDB is the forum-default answer for IoT dashboards — and it's half an answer. Here's the honest comparison: what the DIY stack does better, what it quietly doesn't do at all, and what four self-hosted services really cost against one serverless deploy.

Open-source IoT dashboards in 2026: what actually works for makers

Most 'best open-source IoT platform' lists are written for factories, not makers. Here's the maker's-eye view: what an IoT dashboard actually needs to do, which open-source options genuinely deliver it, what each one costs to operate, and when a serverless deploy beats them all.
