Sonoff Micro - USB Smart Switch Adapter - ewelink only - no Home Assistant :(

drzzs.com/sonoff_micro
This is a nifty little idea. A "smart" switch for USB powered devices. It works well (as expected) with the eWeLink app. Unfortunately, it isn't ESP8266/8285 based, so it won't run Tasmota. I tried the Home Assistant Custom Component for eWeLink devices, but didn't get it to work. There's probably a way to get it working with HA, I just don't know it.

[@5speedfatty]

nice timing Doc, I was just looking at these today, if they dont support HA its a big NOPE from the Fatty! Side note we can totally make our own smart usb charger using a sonoff SV and you can even patch the data lines across so the data would work

[@ECEtek]

You can get the same effect (in a slightly larger footprint) by using an ESP01 and one of the Version 4 ESP01 relay boards. Plus you can then flash it with Tasmota. It will probably work out slightly more expensive once you factor in a USB lead extension (to get the male and female ends of the USB connections) and If you want to encapsulate the package it can get a tad more expensive. It is easy to add an external switch and a template already exists on the Tasmota site for the relay boards. You'd have to tweak the template slightly for a switch but it isn't too difficult. A bonus is that if you are smart in the length of USB extension cable you buy and the way you cut it you can maintain USB data pass through, which I believe is not available on these Sonoff mini device! I enjoy your videos - you've helped me a lot! Thanks.

[@HandeeGaming]

They do have data passthrough, and you don't need to buy an actual cable, you can buy just the connectors which are very cheap, and solder the wires you need to it. The most expensive part is going to be the wifi microcontroller, as the sonoff micro is cheaper than most dev boards. If cost is the most important factor, this is a buy not a diy

[@jon9947]

I thought this would be neat before I started watching it, then about 20 seconds into the video I had the realization that I could get the exact same thing, but with HA compatibility, by simply plugging a phone charger into a smart switch and it would have virtually the same footprint. This just seems like another bad Sonoff product. If this product had been thought out just a little better it could have been useful and unique. None the less I finished watching the video, but only because I enjoy watching you :)

[@aleksandrrr]

what other sonoff products are bad?

[@richlaue]

But at 6.95 it is cheaper than a smart switch and still works with Alexa and Google home.

[@jon9947]

I paid about $6 for my Tuya compatible smart plugs, so it actually isnt cheaper, its just less compatible. Last time I gave my opinion of Sonoff products I caught too much crap from the community, so outside of what I already said I'll just keep my opinions of Sonoff to myself. If you like them, more power to you.

[@eclass1988]

Thank you so much I bought this product from months ago from Amazon I was going to return it they told me to keep it so I had it sitting here found your video today to give it another try the fact that the issue was you have to scan the QR code super fast and if you ever lose it it’s basically impossible to connect this time your video help me out 1000% now I can finally shut off my touch light once I get into bed without having to get up if I ever forget to turn it off LOL thank you!

[@letsfixsomethingathome8536]

Sonoff/ewelink HA component needs a different username account as EWELINK will only allow A SINGLE use instance..so your phone instance is using it.. Try sharing from the phone to new account for just HA.

[@Leonvolt28]

I've used the ewelink custom component ever since I started using home assistant. Then I started flashing things with esphome. I've flashed my last sonoff today, so now everything runs locally. I had to add a line under sonoff component when I started using it. It was something like 'debugging: true' I then had a debug switch get all ewelink stuff into home assistant. You can disable debugging after toggling the debug switch. The other lines may also be important for the component to work (that might have been the reason for the error) I personally didn't really like the component because not all switches will toggle when they are in a group.

[@BaconRanch]

Hey Z, why not just check in unused entities? You do use lovelace? Top 3 dots in left hand corner. Configure UI, hit it again ....boom. Worked for me. Thanks, been looking to get Sonoff in HA for a bit

[@Rmharnisch]

"for startsies" haha! Love that.

[@DrZzs]

;)

[@ag4728]

The KMC 5-Outlet Wi-Fi Surge Protector has a USB switch and works with HA through tuya or smart life. So far I am happy with it. Haven't tried to tasmotize it yet though.

[@Aymanarraj]

Can be useful to control TV backlight connected to the TV’s USB. Sometimes these light are too bright and you don’t want them on with the TV. Maybe even combine it with a night mode IR command, where TV switches to a dimmed mode and the switch turns off the backlights.

[@AAtta-3286]

I'm using a talentcell mini ups and have it connected to my Hubitat hub. Recently I have a rule set up when there is a power failure in my house that a battery backup z wave extender informs Hubitat its switched to battery and the hub then powers down. The problem was, if the Talentcell still had power the hub would not reboot after power was restored to the house. The hub had to be disconnected from the talentcell power and plugged back in. This Sonoff switch was my answer. I'm waiting for delivery but basically I want to plug it into the usb port of the Talentcell ups and the output end into the Hubitat hub. Now I should be able to turn off the ups power to the Hub, then turn it back on so the hub can reboot remotely. My only question is, with firmware updates, does the Sonoff automatically install new firmware which would cut off power to my hub OR do you manually initiate a firmware update from the app. Thank you again for your video

[@PremShah_Realtor]

May be use as a Phone Charger which cuts off power when phone charges 90%. We can use Tasker to read Phone battery level and then trigger command to turn off this device. Will prevent over heating, over charging when plugged in over night

[@OldCurmudgeon3DP]

Charge to 80%, turn off, turn back on at 20%. That would require HA reading the tablet battery state though. Heard of doing this for HA displays mounted in-wall so the battery doesn't tank prematurely. Lot of tuya devices are getting new chips that can't be flashed w/ Tasmota or so I hear.

[@TomDubYeah]

I vote for tearing it apart anyway!!!!!! I wanna see what inside

[@jefferygrantham5582]

Totally agree! Get your money's worth by tearing into it, Doc.

[@nkgudih]

Dr. I have a Toyota Hiace panelvan and has a KILL switch based on the Sonoff 5v wifi switch. All my vehicles have mobile router WIFI and I had a problem of controlling the charging from my car battery, and also overcharging of the mobile router WIFI. I am going to connect the router through the Sonoff USB, and schedule recharging to the router to prevent damaging its battery. So, for me its usefull indeed

[@abobobo943]

Good for charger or lightning. Thanks Sir.

[@Thamli]

Good for usb lights, I've got a pixel strip on usb power from IKEA. Works great

[@DrZzs]

excellent! I've not decided how I'll use it yet. Probably for the LEDs on my 3d printer.

[@EsotericArctos]

Wouldn;t it be more power efficient with a Smart Socket and a USB Power Supply? You still need a USB Power Supply for this anyway. Maybe if you run it off a USB Powerbank, but the standby current would drain that fairly quickly anyway.

[@franktedeschi5331]

Hello my name is Frank I am new to sonoff I wanted to know if it is possible to control a s31 lite with a rm433 remote. I also picked up a 433 rf bridge. Thanks for the help.

[@RSAPemi]

Hi did you know then eWeLink account can works only on one device in one time. If you sign up in another device ( app) you will be automatically disconect from the first one. The solution is make secondary eWeLink account this put in Home Assistant, end in your main eWeLink account share your device with the secondary one.

[@Alcatraz2k]

First :D Sounds interesting, but as you say very limited uses. Not something I'm going to run out and buy

[@DrZzs]

ya. same here.

[@jamesking890]

might be ok for powering something like a USB fan on a timer or IFTTT trigger or something.

[@Followmyprofile]

Hello! Will it work if I connect USB Flash Drive via Sonnoff on my laptop? Will my laptop "see" flash drive?

[@rufusm_au]

Just rebooted my HA and the ewelink integration works again and so does my USB Smart Switch Adapter. It comes up with four switches (CH1-4) but only CH1 does anything (found in Developer States UI). I share my devices on my ewelink app login with a different login on HA, but still get a message on my phone when I switch the USB device on HA. Will have a play with Automations now. Using it to control a USB powered mosquito/fly killer in the kitchen. Don't despair DrZzs.

[@vandownxtheriver]

It’s the new way to give power control in the Echo Flex USB port! That’s all I can come up with!

[@DrZzs]

haha that must be it!

[@novasat1]

@DrZzs To work in HA, the configuration e-mail is not your e-mail but the e-mail of your shared device.

[@ronm6585]

Thanks.

[@TradieTrev]

The 5V sonoff can run tasmota though. Put a usb plug on one of them.

[@DrZzs]

true!

[@joshuarosen6242]

Presumably this requires taking it apart. How easy is it to do that without permanently damaging the case?

[@modsterca]

no data pass through on a pass through usb plug wtf is that all about?

[@moosew168]

Hi! Did you get it to work with Home Assistant over time?

[@TheSuitedEngineer]

It is now supported by the Sonoff LAN integration that you can install on Home Assistant using HACS

[@dikl2689]

Surely if you'v got the nouse to solder on connectors to flash it you could wire up an ESP01/relay module to do the same thing for you.

[@DrZzs]

agreed

[@CortexGaming]

I started using the addon a while back, at first I thought it was bad. Turned out since I'm lazy and didn't share my devices with an account as it recommended, it was causing issues where my devices would appear as unavailable in Home Assistant. Once I fixed that it was a lifesaver. No more fashing or soldering and tons of work. Sure some server in China as my data, but eh :l.

[@chunhui3936]

I use this to connect my water pump for my hydroponic farming system to my solar panel... and this was my only choice lol

[@hjkaye]

I see limited use when only usb ports are available. Plenty of smart plugs with USB ports, especially using the tuya platform.

[@DrZzs]

amen

[@karthik1sky]

How long does it last on a power bank (10000 milliamps) ? Any idea?

[@ECEtek]

ESP01 can be quite power hungry and will empty a two cell AA pack in a day just sitting idle if you don't implement deep sleep etc. I appreciate that this isn't ESP8266 based but would imagine the power overhead is similar - probably caused by constantly checking back over the wireless link to maintain a connection with your router. Might be worth giving it a try and then letting everyone know how you get on. ;0)

[@albino5759]

can u transfer data thru the device?

[@lopez8971]

This would be great to turn off Wyze Cams in your bedroom or somewhere you don't want to be creeped on online at certain times.

[@SanDiegosHetch]

Absolutely true or more importantly to power cycle the camera if and when it goes offline and done have access to its interface.

[@lordgarth1]

He said it doesn’t pass data.

[@SanDiegosHetch]

Lord Garth it doesn’t have to pass any data .... just power cycling

[@ollyalme]

Relying on memory or automation for cameras in bedrooms sound like an embarrassing accident bound to happen sooner or later :)

[@SanDiegosHetch]

Olly Alme can’t agree more. Big no no

[@Professionalgunowner]

Will is wake a pc?

[@solarmandave]

This would work great to reset my ardinio board. Every once in awhile to power cycle.

[@mayanktiku9900]

I still don’t get the point of this product. The usb is connected to a power brick which is connected to an outlet. I could just get a smart plug

[@dartfrogdk]

they are great for filling the garbage can ;o) I got 5 they will end up in the landfill

[@lordgarth1]

No data pass through is probably the only thing that would make this safe to use. It’s way too easy for a usb device with malicious firmware to compromise another device. I’d still want to make sure that only the power pins were connected.

[@Gaunty213]

I have used the sonoff plugs through HA and IFTTT, simple fix

[@Mrcaffinebean]

I guess the idea is the use this where only usb outlets are available. Maybe off a computer? Like you said, not much use.

[@BuzStringer]

No home assistant means it's a pass anyway. But no data passthrough is A HUGE oversight, i could think of a dozen uses. Sometimes my ambibox prevents my htpc from sleeping i could just power it off, or disable wireless dongles when I'm not gaming (some of them flash) restart troublesome USB devices without unplugging them, keeping my VR headset powered off when I'm not using it. Make flashing Arduinos easier. Argh! So close!

[@JohnJoeMorganTheNorthernOffice]

Running 0.104.3 Hassio. For the Sonoff custom component ... just spent a frustrating few hours going through this but well worth it and thanks to DrZzs for bring it to my attention and @peterbuga for the graft. I had lots of tries with the config but the keys are: 1) Place your telephone number in single apostrophes with no zero before the international code (so as you'd actually dial it) 2) region must the br same as your phone. Make a guess reboot and check the log and it's tell you what it wants if there's an error. sonoff: username: '[phone]' password: Password! scan_interval: 60 grace_period: 600 api_region: 'as' entity_prefix: True debug: False I have 2 switches now in HA, a S26 and S31. The S31 is reporting current, power and voltage but not signal, energy_total, energy_today or energy_yesterday as my Tasmota S31 is.

[@DrZzs]

I'll give it a try! thanks! I wish I could pin this comment to the top somehow.

[@sk3tch4d]

No data pass-through? No Home Assistant? Ouch.. thats frustrating.

[@DrZzs]

ya, they missed an opportunity there. Could have been a more useful device with those changes.

[@LoomisRex]

What about Tuya Connect ?

[@DrZzs]

This doesn't use Tuya. There isn't an equivalent for eWeLink.

[@0Scopeo]

Any one got these working with IFTTT? Very happy with it just a little disappointed it doesn't (currently) show up in IFTTT like my other sonoff equipment.

[@ernstoud]

Yep, just tried. Doesn’t show up in the ifttt settings. What a stupid product.

[@EsotericArctos]

I saw this reviewed on @UCdRpPAsQbIaVpn_vS2_omPw's channel a couple of weeks agoa and struggled to find a use case for it. External HDD's of USB2 type turn off with the PC. LED Lights - well most work better off a dedicated PSU and not a USB one. Phone charger. Well, you manually disconnect the phone anyway, so unplugging the charger is no big deal. It needs to run off a USB power supply anyway, so power saving isn't even a deal. Even with a Raspberry Pi this would make a bulky PSU. The footprint is the same as a smart socket with a 2.5amp phone charger that again can be controlled in Home Assistant directly. A smart socket will save more power as it would turn off the actual PSU. I really have no idea what to use this device for that existing phone charger devices can't already day with a smart socket that works in Home Assistant. Doc, this is a great review, no doubt, but I just struggle trying to find a reason for the device to exist.

[@injector221]

This would be useful to extend the battery life of your phone. Since Li doesn't like to stay at 100% SOC. you could create a Tasker profile to watch the SOC while charging and when it gets to 80-90% send an API hit to turn off the micro. Charging Lithium to 80-90% can extend batteries drastically.

[@DrZzs]

That's what I've heard. I assume they were thinking of things like that when they made it. I think a lot of newer phones have that kind of protection built it.

[@injector221]

@@DrZzs it's not that. Li can be charged to 4.2v and still be perfectly safe. It's just the way the chemistry works if you don't charge it that high you'll extend the life. In other words by charging to 90% you can get upwards of 1k cycles more but that would mean leaving capacity on unused which for the usual user would be an issue. Not to mention the faster that battery dies the sooner you'll get a new phone. I've downloaded ampere on my phone and at 100% it sat at 4.3v per cell which is Def not safe.

you can use this using the stock firmware and as a local device I have a bunch of ewelink devices on home assistant all with stock firmware Start with link github.com/mattsaxon/sonoff-lan-mode-homeassistant you have to manually setup each device as a switch with its device ID and its API KEY to get these you have to turn on its access point feature then have a wireless device "I prefer a wireless computer" attach to it look for anything the says ITEAD-xxxxxxx connect to it and the password is 12345678 use the browser and type in 10.10.7.1/device it will return its Device ID and its APIKEY that you need copy them as you will need them
