Follow the instructions on the above project's wiki to build and install the firmware.

== Configuration ==

Watch the MQTT channels <code>tele/sonoff/INFO1</code> and <code>tele/sonoff/INFO2</code> on buzz (username pi/password ''[redacted]''). 
(e.g., <code>mosquitto_sub -h buzz.0x20 -v -t "tele/sonoff/#"</code>) while the device is first booted.

You will see:
<code><pre>
tele/sonoff/INFO1 {"Module":"Sonoff Basic","Version":"5.14.0b","FallbackTopic":"DVES_8E52C7","GroupTopic":"sonoffs"}
tele/sonoff/INFO2 {"WebServerMode":"Admin","Hostname":"sonoff-4807","IPAddress":"10.20.1.127"}
</pre></code>

There may be other lines between these.

Note the suffix after DVES in the first line and after sonoff- in the second. Make a label containing those suffixes separated by a slash, e.g., for the above lines, the label would be <code>8E52C7/4807</code>.

I found the following messages useful:
<code><pre>
# Set switches to send both transitions. 2 is the same but inverted
cmnd/DVES_189EE1/SwitchMode 1
# Set target device to control from switches. No message controls itself
cmnd/DVES_189EE1/SwitchTopic DVES_1141BC
# Control target device from buttons
cmnd/DVES_189EE1/ButtonTopic -m 'DVS_1141BC'

# Set relay status (also try ON and OFF)
cmnd/DVES_189EE1/POWER1 TOGGLE
</pre></code>
