SonoffPost is used to operate Sonoff switches without usin the eWeLink app.
	Ths allows for manual or automated operation of devices without using the phone.
	It is a VB6 Windows program with parameters and inputs

Standard calling:

SonoffPost   Deviceid Request

EG SonoffPost 10006006f on
This will turn the device on.

Parameters

DeviceId: the eWelink deviceID [from Settings in the eWelink app].
Request [optional]: can be: on, off, info or omitted
	on: turn the device on
	off: turn the device off
	info: return a file, SonoffPost.log with device details
	if omitted it checks the status of the device

Return code:
0: the device is off
1: the device is on
5: there is an error

10: the device is not responding

When switching on and off the program checks that the action succeeded and returns the current state, if it failed it returns 5

Note: Sonoff Basic R3 is a 4 state device. it can be used to detect if a circuit to which it is attached is on or off, as well as detecting devices it feeds are on or off.

EG SonoffPost 10006006f 
This will return error code 10 if the device is powered off, eg all devices on its circuit are off

If it returns 1 or 0 then the circuit to which it is attached is active.

The 1 or 0 indicates also the state of the output of the Sonoff is on or off, for any devices attached to it.

inputs

a tokens.txt file [sample included] must reside in the folder of SonoffPost.exe

This contains the tokens needed for access and can be created the first time with the following procedure.

Obtaining the AT and RT tokens

These tokens authenticate the program with the eWeLink cloud and are stored in tokens.txt in the same folder as the executable. They need to be obtained once initially, or again if the file is lost.

Requirements:

    A PC with Firefox or Chrome browser
    Your eWeLink account email and password

Steps:

    Open Firefox and press F12 to open Developer Tools
    Click the Network tab
    Right click in the network request list and enable Persist Logs (Firefox) or tick Preserve Log (Chrome)
    Navigate to web.ewelink.cc and log in with your eWeLink account
    In the Network tab filter box type login
    Click the login request that appears — it will be a POST to something like eu-apia.coolkit.cc
    Click the Response tab
    In the response JSON find and copy the values for "at" and "rt" — they are long hexadecimal strings

Create tokens.txt in the same folder as the executable with exactly this content:

at=paste_at_value_here
rt=paste_rt_value_here

Notes:

    The at token expires after approximately 30 days but is refreshed automatically by the program — you should never need to repeat this process
    The rt token is also automatically refreshed each time at is refreshed
    The only reason to repeat this process is if tokens.txt is deleted or both tokens have expired due to the program not being run for an extended period
    Tokens are specific to your eWeLink account and cover all devices on that account
    
    All actions are performed via Cloud API which means the device remains fully controllable by all normal means in addition to the program.
    It also means that the eWeLink will parallel the requested states.
    A status check (omitting the Request parameter) will return code 10 if the device has no power, effectively confirming whether the circuit it is connected to is active or not.

This SonoffPost version is for EU users but may work elsewhere using something different to eu-apia.coolkit.cc
