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

Sonoff T2 wiring Thailand

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 […]

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

Sonoff T2 Switch Zigbee Bridge Motion Sensor

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

ESP32 floor heating valve controller

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 […]

Iono RP – An industrial PLC with a Raspberry Pi RP2040 MCU

Iono RP Raspberry Pi RP2040 PLC

Raspberry Pi RP2040 MCU has been used in many boards, but I think I had seen the dual-core MCU in a PLC, or even any industrial products just yet. Sfera Labs Iono RP is a compact I/O module (PLC) with a Raspberry Pi RP2040 microcontroller that’s programmable in C/C++ and MicroPython, or even the Arduino IDE. The DIN-Rail mountable, RP2040 based industrial PLC offers digital and analog input and output lines, power relays, and an RS-485 interface, supports power input from 12V-24V with all signals accessible through terminal blocks. Sfera Labs can also provide some optional options such as an RTC or an earthquake sensor module.
