There is a very legitimate use case for a sonoff micro over a smart plug. The sonoff micro makes it possible to use a USB power bank as a low voltage UPS while still being able to have a smart switch on the USB device you are powering. This comes in very handy for the sound machine in the baby's room. It stays running in case of a power outage with a USB bank, and I can still have smart device control.

[@georgei2480]

If sonoff moves away from open source, they will die very quickly. that's a massive part of there market share.

[@MayankJairaj]

Thanks for the review! Bought it and works alright, the size is def an issue - it does cover a one usb port on my charging station but the problem was mitigated by using the rightmost port. Is the casing like this due to heat or something else?

[@notenoughtech]

You could use a short usb extension lead to bypass the issue with its size.

[@MayankJairaj]

@@notenoughtech oh yes thanks I'm so dumb haha

[@notenoughtech]

Sometimes the easiest solution escape our heads :)

[@evanchapman6339]

The 4switching channels makes me think they may include 4USB outs.... They have the space in the 'box' for 3 more. All powered off one USB input.

[@DaveSquibbSr]

This thing wasn't made for data lol it was made for things like USB lights that you leave hooked up to USB power supply such as a solar generator.

[@ronm6585]

Good stuff, thank you.

[@chris0x00]

Thank you for confirming no Espressif chip

[@notenoughtech]

I'll be playing with the new one soon. I'm excited to look inside and see what I can do

[@stormtrooper88]

im hoping to use them in a light display to remotely turn some usb lights on and off on a tree in my yard. it will be powered by a small 10,000 mah battery pack. if i did the math correct it should last the entire holiday season being on just a few hours at night. i didn't want to run extension cords to power it and thought this to be the best solution. i figured i could just put it all in a ziplock bag to keep any water/snow out. any input on this idea or any problems you think i might encounter would be appreciated. thank you....

[@notenoughtech]

Other than keeping it safe from moisture you should be ok.

[@guillaumekircher18]

Easy to use and effective

[@giovanniturco6428]

Hi fantastic video again I do have the Sonoff micro I have noticed you can’t use the Ifttt like sunrise and sunset the same way the D1 dimmer switch

[@notenoughtech]

You could do this with nodered. I will have a tutorial tomorrow showing something cool you can do with the micro

[@giovanniturco6428]

NotEnoughTECH hi can’t wait to watch it

[@notenoughtech]

its online :)

[@ashlyndayanarain9801]

I have a sonoff micro and i have connected to my led lights but the led lights has a button on the usb plug, to switch on and change functions. I have connect to my phone and Alexa but it wont switch on unless i press the button on the led light usb but it will turn off with alexa or the app. Can you please help on i can switch it on without pressing the button

[@EsotericArctos]

It looks like Sonoff might be moving away from DIY / Hacking. Unless this new chip is just cost saving or maybe in preparation for more ZigBee devices. I struggle to find a use over a smart plug though, given it only switches the low voltage lines.

[@notenoughtech]

I hope not, the dev pads are still there so I'm keeping my fingers crossed! The charging profile works great tho :)

[@EsotericArctos]

@@notenoughtech I might have to do some research on the new chip

[@HiltonRalphs]

I bought two to switch my Chromecast devices. I don't always need them powered up as I use my TV as a second screen.

[@notenoughtech]

Oh that's cool

[@aihysp]

if the data from usb can go to wifi... i think we have a nice lilte key logger here :)

[@notenoughtech]

Haha oh yeah that's definitely a possible issue ;)

[@DiyintheGhetto]

Hello you can almost manually add the data wires with a little bit of wire. That is how i would do it. But over all awesome video.

[@notenoughtech]

D+ and D- are fused with a resistor so it would be problematic. It's part of how BC1.2 is negotiated in this instance.

[@aj-cb9ht]

Hi can you please make a video of it if possible?

[@notenoughtech]

Without modification to PCB it's not going to work so I'm not going to add the data lanes. There are some usb devices that allow this linked in the comments of this my USB 'c hack

[@klim4598]

@@notenoughtech Sorry, but where is the links to other usb devices that supports data transfer and on/off? I can't find it.

[@klim4598]

@@notenoughtech I removed resistor and wired D+ D- directly and data works too now!

[@Farmboy1927]

Can you convert it to zigbee?

[@notenoughtech]

It would need an entire new PCB

[@Farmboy1927]

@@notenoughtech that's a bummer, but thanks for the information!

[@randolfaquino9998]

how much power does the micro use?

[@notenoughtech]

I'd have to plug it but probably around 75- 100mAh

[@Daimoniann]

It is 0,4 watt. Same for on and off. This is more than I expected. I also use Shelly1 Plus (12V) with esp32 and it consumes 0,38 w when relay on and 0,15 w when relay is off (in eco mode). If they use bistable relay, it can consume 0,15 even in on state.

[@SmithyScotland]

New proprietary chip part of their plan to sell you ewelink premium subscription?

[@notenoughtech]

I thought at first it's the current draw of esp that forced the change but the new one draws similar power.

[@bogorad]

1. No ifttt support! 2. I failed to access it via API - zero devices returned upon successful login to ewelink. Did you do anything special apart from just login and enumerate devices?

[@notenoughtech]

IFTTT has webhooks so you can interact with it. Something tells me it could be your region? these are not documented well, what country is your account registered to?

[@bogorad]

@@notenoughtech 1. Sonoff support told me they do not support USB/micro via IFTTT yet. When you try to create a rule in IFTTT->ewelink, zero USB/micros are found. 2. I tried using node-red ewelink node. It does see my mini, but fails to see my micro.

[@notenoughtech]

Strange. Are you using the same as node as mine ? Clearly I don't have this issue for some reason 🤷🏼‍♂️

[@bogorad]

@@notenoughtech Not sure if it's the same one. But it logs me in, shows me the mini, but not the micro. Did you try accessing micro via IFTTT?

[@notenoughtech]

Not via app as I route everything through node red it's easier that way

[@ahdpahdp5154]

Спасибо что разобрал и показал.
