SONOFF Zigbee Bridge Pro gateway supports up to 128 sub-devices

SONOFF Zigbee Bridge Pro

ITEAD has just introduced the SONOFF Zigbee Bridge Pro WiFi <-> Zigbee gateway as an upgrade to the Sonoff ZBBridge gateway launched in 2020. Both devices look exactly the same, and the changes are under the hood with the EFR32MG21 and ESP8266/ESP8285 combo being replaced by Texas Instruments SimpleLink CC2652P and ESP32 chips to boost the number of supported sub-devices from 32 to 128. Other changes include the addition of a buzzer acting as an alarm or doorbell chime, as well as a “built-in high-precision local RTC” for gateway time synchronization of local scene schedules. SONFF Zigbee Bridge Pro (aka ZB Bridge-P) specifications: Wireless MCUs Texas Instruments CC2652P SimpleLink Arm Cortex-M4F multiprotocol 2.4 GHz wireless MCU with integrated power amplifier Espressif Systems ESP32-DOWN-V3 dual-core processor with WiFi 4 and Bluetooth LE Wireless Connectivity – 2.4 GHz 802.11b/g/n WiFi 4 and Zigbee 3.0 Supports for up to 128 sub-devices Support for […]

SONOFF ZBMINI-L Zigbee 3.0 Smart Switch works without neutral wire

Sonoff Zigbee switch no neural wire

When using a wireless switch like SONOFF T2 a connection to the neutral wire is needed to power the device, but this is not always feasible/practical as many lights as cabled without a neutral wire. SONOFF ZBMINI-L Zigbee 3.0 smart switch solves this issue as it does not require a neutral wire. Simply connect the two wires for the light and you are good to go. ITEAD says its solution does not require an extra anti-flicker module and relies on an “advanced electricity extraction technique”. SONOFF ZBMINI-L specifications: Connectivity – Zigbee 3.0 via TI CC2652P, up to 50 meter range (line of sight) Input – 100-240V 50/60Hz up to 6A Output – 100-240V 50/60Hz up to 6A Max. Load Resistive – 1380W Max @ 230V, 720W Max @ 120V LED – 300W Max @ 230V, 150W Max @ 120V Dimensions – 54 x 45 x 24mm (supports 35mm DIN Rail […]

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 […]

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 […]
