Seeed Studio 2-Channel Wi-Fi AC Relay Review – An ESPHome smart switch with power meter function

Seeed Studio 2-Channel Wi-Fi AC Relay Review Home Assistant

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 […]

PCIe3.0 to Dual M.2 HAT+ for Raspberry Pi 5 features ASMedia ASM2806 PCIe 3.0 switch

PCIe 3.0 to dual M.2 HAT for Raspberry Pi 5

We’ve already covered Raspberry Pi HAT+ boards with multiple M.2 sockets with various keyings including the Geekworm X1004 HAT+, Pineboards HatDrive! AI, and  HatDrive! Dual with two sockets, and the Geekworm X1011 with four M.2 Key-M sockets. So when I saw Seeed Studio introduced a dual M.2 HAT+ board I initially thought it was uninteresting being a very similar board. However, all aforementioned PCIe to M.2 HAT+ boards are based on either the ASMedia ASM1182e or ASM1184e PCIe Gen2 x1 packet switches with 5GT/s shared bandwidth, and Seeed Studio’s PCIe3.0 to Dual M.2 HAT+ for Raspberry Pi 5 features instead an ASMedia ASM2806 PCIe 3.0 switch supporting up to 8GT/s shared bandwidth through the Raspberry Pi 5’s PCIe Gen3 x1 interface. Seeed Studio PCIe 3.0 to Dual M.2 HAT+ key features and specifications: Supported SBC – Raspberry Pi 5 and potentially other SBCs with a PCIe FFC connector like the […]
