SONOFF ZBMicro Zigbee USB smart adapter adds any USB device to your Smart Home setup

The new home automation device from ITEAD is based on a Silicon Labs EFR32MG21 multiprotocol SoC, works with the usual eWelink app, as well as Home Assitant and OpenHAB open-source solutions when the server is fitted with a compatible Zigbee 3.0 USB dongle

WiFi USB adapter prevents overcharging
The SONFFOFF ZBMicro is supposed to prevent overcharging although it’s unclear whether that’s an issue with the latest smartphones

The SONOFF ZBMicro requires a Zigbee 3.0 hub such as the SONOFF iHost, SONOFF NSPanel Pro, Echo Plus 2nd, Philips Hue, or SmartThings hub V3… It works with the eWelink mobile app, but it is also compatible with open-source automation platforms such as Home Assistant with Zigbee2MQTT integration and openHAB as long as those are fitted with a compatible Zigbee Dongle such as the SONOFF ZBDongle-E or the SkyConnect USB stick. ITEAD also explains the ZBMicro can work as a Zigbee router to extend the range of your Smart Home Zigbee network. A user manual is available but with limited information.

ITEAD sells the SONOFF ZBMicro for $12.99 plus shipping, but as usual, you can get a 10% discount when using the coupon code CNXSOFTSONOFF, and orders over $89 get free shipping. Paisit will soon get a sample along with the upcoming ZBbridge-U “Zigbee Bridge Ultra and Matter Bridge” supporting up to 256 Zigbee sub-devices, so you can expect a review within the next few weeks on CNX Software.

  1. A bit expensive when the XY-WFUSB is around and can be flashed with Tasmota/ESPHome/Espurna, can act as a PWM controller when flashed with a custom firmware and supposedly supports up to 100W of power delivery.

    Ok, Sonoff’s is Zigbee. Nice.

    I do prefer the form factor of this device over the XY-WFUSB.

    1. Thanks for mentioning the XY-WFUSB, I agree it looks much more promising.

      But AFAICS it doesn’t support any kind of power metering, just like the ZBMicro… if it did, then it would be perfect for a use case of mine.

      Do you happen to know any similar devices that do?

  2. Not seeing the benefit over using a “standard” mains voltage plug adaptor, plus it would have the advantage of turning off the USB charger as well

  3. I have been using something similar for voltage ranges 5-12V and 2.5A for my USB lights. It was not a problem to get 5V 10W light which is strong enough. It uses a Wi-Fi connection and is linked to the Smart Life cloud system.
    This one has just only 1 LED and it is also compatible with TUYA while the other WiFi one has 2 LEDs and is compatible with EWeLink. So you need to be careful.

    Pricewise they are cheaper than the reviewed piece however you are not dependent on a cloud and the internet connection malfunctions or glitches. And who knows how long these cloud services will run?

  4. I kind of don’t see the point. You still need the add a USB charger, it’s just in front of it. The same xan be accomplished with a normal mains smart switch and the USB charger plugged in after it… What advantage does this new product give?
