Sonoff-MQTT-OTA - End of Life

Sonoff

This software is End of Life. New features will be introduced in Sonoff-Tasmota available on https://github.com/arendst/Sonoff-Tasmota

Provide ESP8266 based itead Sonoff with MQTT and 'Over the Air' or OTA firmware.

Prerequisite

Install the ESP8266 development environment from esp8266-dev.

Copy the sonoff code files as follows:

Create directory
```
esp8266-dev/work
```
and copy directory
```
sonoff
```
and file
```
espupload.php
```
into it
Replace file
```
Makefile.common
```
in directory
```
esp8266-dev
```

Install php and a local web server (ie apache) for OTA and copy directory

api

in webroot.

Compile and upload

Update

sonoff/user/user_config.h

with your specific Wifi and MQTT parameters.

Compile source with

make

and flash once to sonoff using cable connection as shown in Peter Scargill's blog with

make flash

Connection diagram

Do not connect AC power during the flash cable connection.

Compile and upload OTA images to your web server with

make clean; make IMAGE=1; make register; make clean; make IMAGE=2; make register

Note: this software is not compatible with Pete's implementation.

Usage

The button on sonoff provides the following features:

a short press toggles the relay. This will blink the LED twice and sends a MQTT status message like
```
stat/sonoff/POWER on
```
three short presses start Wifi smartconfig which allows for SSID and Password configuration using an Android mobile phone with the ESP8266 SmartConfig app. The green LED will blink during the smartconfig period for 100 seconds. The MQTT server still needs to be configured using the
```
user_config.h
```
file
four short presses start OTA download of firmware. The green LED is lit during the update
pressing the button for over four seconds resets settings to defaults as defined in
```
user_config.h
```
and reboots sonoff

Sonoff responds to the following MQTT commands:

the relay can be controlled by
```
cmnd/sonoff/power on
```
,
```
cmns/sonoff/power off
```
or
```
cmnd/sonoff/power toggle
```
. The LED will blink twice and sends a MQTT status message like
```
stat/sonoff/POWER on
```
. The same function can be initiated with
```
cmnd/sonoff/light on
```
the MQTT topic can be changed with
```
cmnd/sonoff/topic sonoff1
```
which reboots sonoff and makes it available for MQTT commands like
```
cmnd/sonoff1/power on
```
the OTA firmware location can be made known to sonoff by
```
cmnd/sonoff/otaurl http://sidnas2:80/api/sonoff/user1.bin
```
where sidnas2 is your webserver hosting the firmware. Reset to default with
```
cmnd/sonoff/otaurl 1
```
upgrade OTA firmware by
```
cmnd/sonoff/upgrade 1
```
show status information by
```
cmnd/sonoff/status 1
```

Most MQTT commands will result in a status feedback like

stat/sonoff/POWER On

Commands supported

The firmware supports both a serial and a MQTT Man Machine interface. The serial interface is set to 115200 bps. The MQTT commands are constructed as

cmnd/sonoff/

The following commands are recognised by both topic and grouptopic:

Command	Description
power	Show current power state as On or Off
power on	Turn power On
power off	Turn power Off
power toggle	Toggle power
power 1	Turn power On
power 0	Turn power Off
power 2	Toggle power
light	Show current power state as On or Off
light on	Turn power On
light off	Turn power Off
light toggle	Toggle power
light 1	Turn power On
light 0	Turn power Off
light 2	Toggle power
status	Show abbreviated status information
status 1	Show all status information
status 2	Show version information
grouptopic	Show current MQTT group topic
grouptopic 1	Reset MQTT group topic to user_config.h value and restart
grouptopic your-grouptopic	Set MQTT group topic and restart
timezone	Show current timezone
timezone -12 .. 12	Set timezone

The following commands are recognised by topic only:

Command	Description
restart 1	Restart sonoff
reset 1	Reset sonoff parameters to user_config.h values and restart
ssid	Show current Wifi SSId
ssid 1	Reset Wifi SSId to user_config.h value and restart
ssid your-ssid	Set Wifi SSId and restart
password	Show current Wifi password
password 1	Reset Wifi password to user_config.h value and restart
password your-password	Set Wifi password and restart
host	Show current MQTT host
host 1	Reset MQTT host to user_config.h value and restart
host your-host	Set MQTT host and restart
topic	Show current MQTT topic
topic 1	Reset MQTT topic to user_config.h value and restart
topic your-topic	Set MQTT topic and restart
smartconfig 1	Start smart config
otaurl	Show current otaurl
otaurl 1	Reset otaurl to user_config.h value
otaurl your-otaurl	Set otaurl
upgrade 1	Download ota firmware from your web server and restart

If the same topic has been defined to more than one sonoff an individual sonoff can still be addressed by the fall back topic MQTTCLIENTID as defined in userconfig.h. The fall back topic will be ```DVES```.

Tips

To aid in finding the IP address of sonoff the network name will be
```
ESP--
```
. So the default name is
```
ESP-123456-sonoff
```

The initial firmware from

api/sonoff/user1.bin

can be flashed using the SDK 1.4 provided bin files with the following esptool.py command line:

esptool.py --port /dev/ttyUSB0 write_flash -fs 8m 0x00000 boot_v1.4\(b1\).bin 0x01000 user1.bin 0xFC000 esp_init_data_default.bin 0xFE000 blank.bin

Use the group topic to address several sonoffs with one (restricted) MQTT command
