MeshCore is a lightweight alternative to Meshtastic LoRa-based off-grid messaging

While Meshtastic is by far the most popular off-grid messaging solution relying on LoRa radios, MeshCore offers an alternative as a lightweight C++ library and firmware designed for multi-hop packet routing and made for developers who want to create resilient, decentralized communication networks that work without the internet. The project’s GitHub repository provides some high-level differences compared to the Meshtastic and Reticulum projects: MeshCore provides the ability to create wireless mesh networks, similar to Meshtastic and Reticulum but with a focus on lightweight multi-hop packet routing for embedded projects. Unlike Meshtastic, which is tailored for casual LoRa communication, or Reticulum, which offers advanced networking, MeshCore balances simplicity with scalability, making it ideal for custom embedded solutions., where devices (nodes) can communicate over long distances by relaying messages through intermediate nodes. This is especially useful in off-grid, emergency, or tactical situations where traditional communication infrastructure is unavailable. MeshCore key features: Multi-hop […]

Seeed Studio XIAO-2CH-EM Review: 2-Channel Wi-Fi AC Energy Meter with two CT clamps, ESPHome preloaded

XIAO 2-channel Wi-Fi AC Energy Meter Review

We have received a review sample of an energy metering device from SeeedStudio called the XIAO 2-Channel Wi-Fi AC Energy Meter (XIAO-2CH-EM). This device uses a clamp-on CT (Current Transformer) method on the live wire that you want to measure, without needing to modify the existing electrical wiring. XIAO-2CH-EM comes with several key features such as dual CT sensors (CT1 and CT2), native ESPHome & Home Assistant Integration, precise measurement with factory calibration, and bi-directional power flow monitoring. While the XIAO-2CH-EM has 2 CT input ports, it will only ship with one CT clamp by default, but users can purchase an additional CT clamp if needed. The two CT channels operate independently, and each one can measure bidirectional power and supports devices using up to 100A of current. That should be enough for an ordinary home. The XIAO-2CH-EM comes pre-flashed with ESPHome firmware from the factory, meaning it can be […]
