SONOFF releases HTTP API for SPM-Main power meter

Sonoff power meter DIY Mode

SPM-Main is the main unit of Sonoff Smart Stackable Power Meter using RS485 to provide up to 128 relays. Besides support for the eWelink mobile app, we were promised an HTTP API at the time of the launch in September 2021. ITEAD kept its promises and has now released the HTTP API for the SPM-Main smart power meter to allow IoT home automation users and developers to control SONOFF devices via existing home automation open-source platform or local HTTP client. It’s the same REST API used for SONOFF MINI & R3 smart switches, but it adds support for power monitoring as well. The API allows you to switch between eWelink and DIY modes as needed, and provides the following functions: Device Status Broadcast – Returns the switch status of all channels with current, voltage, power, overload status, RS485 communication status, and more Get the List of Sub-device – List of […]

Meet ESP-C3-M1 and ESP-C3-M1-I ultra small ESP32-C3 mini modules (Sponsored)

Half-year ago, Ai-Thinker launched new ESP32-C3 series modules that are fully pin-to-pin compatible with ESP8266, namely ESP-C3-12F, ESP-C3-32S, ESP-C3-01M, ESP-C3-13, ESP-C3-13U. After several months, the company got further requirements about the modules, notably in terms of size. So based on the demand, Ai-Thinker has now added the ESP-C3 mini series family starting with two modules: ESP32-C3-M1 and ESP-C3-M1-I measuring 16.6×13.2mm and 12.5×13.2mm respectively. The ESP-C3 mini series modules are equipped with the Espressif Systems ESP32-C3 32-bit RISC-V MCU featuring 2.4 GHz Wi-Fi & Bluetooth LE 5 connectivity, as well as a wealth of peripherals including UART, I2C, I2S, infrared, PWM, general DMA controller, USB serial port/JTAG controller, temperature sensor and so on. Some of the wonderful features of the new ESP-C3 mini modules include: ESP32-C3 MCU – 32-bit RISC-V single-core processor up to 160 MHz, with 400 KB SRAM, 384 KB ROM, 8KB RTC SRAM Storage – 4MB SPI flash […]

Setting up a motion activated light with Sonoff Zigbee sensor and T2 WiFi switch

Earlier this month, I received a Sonoff ZBBridge Zigbee gateway, a motion sensor, and a Sonoff T2 wireless switch in order to set up everything to work as a motion activated light using Zigbee and WiFi through the eWelink Android app and cloud service. You can check out the first post to have a closer look at the hardware and accessories. We’ve now had time to configure everything and will report the results of the project in this post. The idea is basically to detect motion with the Zigbee sensor, which then transmits the info through the gateway, and the T2 switch is controlled by the eWelink cloud. Last time around, I thought I had a switch with a neutral wire at home, but I did not check in detail enough, and I’ve been unable to use it. Without suitable switches in my home, it was not practical to rewire […]

TQ Embedded launches NXP i.MX RT1170 SoC module and SBC

TQ Embedded (aka TQ) has just announced the availability of the TQMa117xL system-on-chip module based on NXP i.MX RT1170 crossover processor family, and as well as MBa117xL single board computer (SBC) based on the 31×31 mm module. TQMa117xL’s small size has been achieved thanks to a 277-pad LGA design, with the module still integrating LP-SDRAM, Quad-SPI NOR flash and EPROM, a PMIC, as well as an optional security chip. TQMa117xL i.MX RT1170 SoM Specifications: Crossover processor (one or the other) NXP i.MX RT1171 with Cortex-M7 @ up to 1 GHz (Consumer) or 800 MHz (industrial), 1 GbE (AVB) NXP i.MX RT1172 with Cortex-M7 @ 800 MHz/ 1 GHz, graphics accelerators and camera/display interfaces, 1GbE (AVB) NXP i.MX RT1173 with Cortex-M7 @ 800 MHz (industrial only), Cortex-M4 @ 400 MHz, 1GbE (AVB), graphics accelerators and camera/display interfaces, tamper inteface NXP i.MX RT1175 with Cortex-M7 @ 800 MHz / 1 GHz, Cortex-M4 […]

Playing with Sonoff Zigbee & WiFi automation – Part 1: Hardware overview

I don’t think I’ve ever used Zigbee, but I’ll soon have the opportunity as ITEAD sent me the Sonoff ZBBridge gateway, a Sonoff T2 2-gang WiFi switch as well as a Zigbee motion sensor. I had reviewed several Sonoff devices in the past, but it had been over three years that I hadn’t. ITEAD recently contacted me basically telling me I could select whatever I wanted from their product list for a review on CNX Software. Since I had reviewed several of the company’s WiFi smart sockets, smart switches, and a light bulb, I had less to play with, and then I thought it might be fun to play with Sonoff Zigbee products. But I did not own any Zigbee hardware, so I had to think about a use case. I have a small annoyance in the house I rent. When we come back at night, we have to leave […]

10-channel floor heating valve controller supports Tasmota, MQTT, Home Assistant

Voltlog has designed an open-source hardware floor heating valve controller powered by an ESP32 WiFi module making it compatible with Tasmota open-source firmware, and by extension MQTT protocol and Home Assistant automation framework. The board can control up to 10 valves triac controlled outputs and spring connectors for a floor home heating system, and also offers a one-wire srping connector, an I2C header, and safety features with two fuses, although it’s obviously not UL nor TUV certified. Voltlog decided to design his own board instead of buying off-the-shelf solutions because of the high price of such products and the lack of open-source firmware for integration into a home automation server powered by Home Assistant. You can flash firmware to the ESP32 either through a VoltLink USB to Serial converter or you can use your own USB to serial converter module through the on-board JST-SH 1.0mm pitch 6 pin connector. This […]
