Sonoff IoT swich

DIY Wi-Fi Wireless Switch For Smart Home With ABS Shell Socket Remote Control Switch Module is an IoT home automation device. This device, also known as Sonoff from ITEAD, can control 110V to 230V AC mains power on/off (up to 7A or 10A depending on document). The switch is controlled with mobile app (or local buttom). The control works so that this IoT device uses WiFi Internet communications to cloud serrvice. For more details read User Guide for ITEAD Smart Home Devices.

Specifications:

Power: <=0.5W

Rate Voltage: 100-260V

Control mode: Mobile APP (Android, iOS)

Transmission mode: Wi-Fi communication;

Power: 7A/1500W

Thsi device is maybe the cheapest IoT which that can control 230V power wirh iPhone and Android. This is ready to use device as it is. I am disappointed since I need to use and install an external app to use it. The app did not feel to be good or reliable (problems in getting the device detected and connected to home WiFi etc..)

It can be also customized if you want. The device is based on very popular ESP8266 IoT chip. The firmware inside device can be flashed just like any other ESP8266 dev board, there is even programming contacts easily accessible (place to solder pin header).

Let’s look what is inside this device. Here is the box the Sonoff IoT swiching device came to me:

Here is picture of the device itself (I had already added mains input cable to it).

For cable connection the device provides normal OK screw terminals.

The case protects the screws well and works as strain relief for the mains cable.

Let’s open the main case to see the electronics inside.

The circuit board looks nice.

On this side of the board the biggest components are the mains power controlling relay and power supply transformer. The IC you see on the circuit board is iW1700 switch mode power supply IC. On the left side the blue disk is VDR that protects agains overvoltage. The big grey resistor is “fusible resistor” that acts like surge current limiter and serious overload protection (like fuse).

On hte bottom of the board the most important components are ESP8266, rectifier and voltage regulator.  The swich mode power supply generates 5V power that is used directly for the relay coil. The 3.3V for ESP8266 is made with linear regulator from that 5V.

Take a note on the cut-outs on the circuit board, they are here to make sure that the mains power traces don’t be too near to each other (to make short circuit).

    Building My Own Smart Central Heating Control System with a Sonoff TH16

    In this video I build my own smart central heating control system based around a Sonoff TH16 with my own custom software built mostly in Python deployed through Docker. The reason for this project was that I wanted a smart central heating system but didn’t want it to rely on any sort of manufacturer provided cloud service.

    Add Nest Functionality to your Thermostat for $5
    https://hackaday.com/2018/11/06/add-nest-functionality-to-your-thermostat-for-5/

    The Nest Thermostat revolutionized the way that people control the climate in their homes. It has features more features than even the best programmable thermostats. But, all of the premium features also come at a premium price. On the other hand, for only $5, a little coding, and the realization that thermostats are glorified switches, you can easily have your own thermostat that can do everything a Nest can do.

    [Mat’s] solution uses a Sonoff WiFi switch that he ties directly into the thermostat’s control wiring. That’s really the easy part, since most thermostats have a ground or common wire, a signal wire, and a power wire. The real interesting work for this build is in setting up the WiFi interface and doing the backend programming

    #110 ESP8266 relay RANT and 4-ch Sonoff first look (Alexa controlled)
    https://www.youtube.com/watch?v=ul2vtDXREBo

    So let’s look at the “improvements” I’ve made to the ESP8266-01 relay module. I’ve rewritten the code for the ESP-01 and generated a new app for my phone, with a simple ON/OFF function. Basically, I’ve turned this unit into something similar to a single channel Sonoff!

    However, it still required more work (and a hack, er, hardware reconfiguration) to do all this and we really should not have to do any of this. I discovered a simpler relay module that also takes an ESP-01 and seemed to be the answer. Was it? Watch the video and find out.

    We also explore the new 4-channel Sonoff Pro that I link into my Amazon Echo (Alexa) with no fuss at all. I’m impressed with this unit. It does what I expected it to do (after setting some DIP switch options) and will definitely form part of my workshop automation project. Nice one, Sonoff!

    So after this all this I’m thinking of my Raspberry Pi-based (Model B3+) hub running MQTT (mosquito) and Node-Red – see what I’m talking about and then please give me suggestions, ideas and examples of what you have done.

    Sonoff is very popular for DIY home automation, but you can make it even better by loading new firmware onto it. Learn how to connect a USB-to-Serial converter to ANY model of Sonoff, even ones that haven’t been released yet!

    This episode isn’t just a series of steps to follow: it’s a tutorial on how to reverse engineer the connections to the ESP8266 / ESP8285 microcontroller, and put it into bootloader mode ready to receive new software.

    Comment:
    Potential improvement: solder a lead to the GND pin of your the PCB with
    the 4-header pin, so you can simply touch it to the GPIO0 test points
    if required. That would alleviate the need to solder your lead to the
    Sonoff.

    Homekit Compatible Sonoff Firmware Without A Bridge
    https://hackaday.com/2019/07/14/homekit-compatible-sonoff-firmware-without-a-bridge/

    To try and simplify things, [Michele Gruppioni] has developed a firmware for the ubiquitous Sonoff WIFI Smart Switch that allows it to speak native HomeKit. No more using a Raspberry Pi to act as a mediator between your fancy Apple hardware and that stack of $4 Sonoff’s from AliExpress, they can now talk to each other directly. In the video after the break you can see that the iPad identifies the switch as unofficial device, but since it’s compliant with the HomeKit API, that doesn’t prevent them from talking to each other.

    Tasmota is an alternative firmware for ESP boards that provides a wealth of handy features, and [Mat] has written up a guide to flashing with far greater ease by using Tasmotizer. Among other things, it makes it simple to return your ESP-based devices, like various Sonoff offerings, to factory settings, so hack away!

    Tasmotizer is a front end that also makes common tasks like backing up existing firmware and setting configuration options like, WiFi credentials, effortless.

    it was quite tricky and only one 1 wire library worked for me so all credit to the author

    i have used a lux sensor for my project

    the main benefit is you can still use ewelink

    i have had the project running for over a year using a lux sensor for switching the back garden lights on and off accurately with a light level

    you have to live with the temperature range settings in the sonoff but you can easily scale in the code to suite

    Shelly Plus on erittäin pieni, joten se sopii katkaisimien taakse, haaroitusrasioihin tai muihin eristäviin koteloihin. Se on kooltaan vain 4.1 x 1,5 x 3,6 cm, joten se mahtuu pienimpiinkin haaroitusrasioihin. 110 – 240 voltin vaihtovirran lisäksi se toimii 12 ja 24 – 240 voltin tasavirralla, mikä on erittäin tehokasta tietyissä tilanteissa.

    Siitä lähtien, kun Shelly tuli markkinoille, se on tehnyt aktiivista työtä sen eteen, että se olisi yhteensopiva kaikkien älylaitteitasi ohjaavien suurten järjestelmien kanssa. Siksi ne ovat erittäin yhteensopivia muun muassa Home Assistantin, Homeyn, MQTT:n, SmartThingsin ja Demoticzin kanssa. Luonnollisesti se tukee myös Amazon Alexaa ja Google Homea.
