Meshtastic Designer helps you build custom Meshtastic solutions with RAKwireless Wisblock components
RAKWireless introduced the Wisblock IoT Modular System in 2020 to let developers easily create LoRaWAN IoT solutions with various core modules, baseboards, and sensor/IO modules. The company kept adding new Wisblock modules year after year, and there are now over 120 modules part of the Wisblock ecosystem. While the large choice of modules makes designing IoT prototypes more flexible, customers often face challenges in checking compatibility and selecting the right modules for the right slots. That’s why RAKWireless has been working on web-based online designer tools for the Wisblock ecosystem. The first release is the Meshtastic Designer used to quickly configure and create their own Meshtastic devices from the module to enclosure, and place an order from there once the design is complete. I’ve given it a quick try myself. I wanted a Meshtastic device with a display, a keyboard, a GNSS module, and an air quality sensor since the […]

Seeed Studio 2-Channel Wi-Fi AC Relay Review – An ESPHome smart switch with power meter function
We have received the Seeed Studio 2-Channel Wi-Fi AC Relay for review. It is an IoT/Smart Home device featuring a 2-channel relay (wet contact) that operates over a WiFi network, and provides an alternative to SONOFF Smart switches like the SONOFF R2 Dual. The Seeed Studio device is a bit larger and instead of relying on eWelink firmware, it natively supports Home Assistant since it’s pre-installed with ESPHome open-source firmware. Alternatively, if you prefer standalone deployment (without Home Assistant), you can manage it via the web browser. In addition to the basic relay function to control the AC-powered appliances, it also acts as a power meter. This is a good ready-to-use option for Home Assistant enthusiasts who prefer not to assemble their own components. Some practical applications include controlling electrical appliances such as lighting. Let’s dive into the details. Seeed Studio 2-channel AC Wi-Fi Relay unboxing The package we received […]
