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

Configuration[edit]

Watch the MQTT channels tele/sonoff/INFO1 and tele/sonoff/INFO2 on buzz (username pi/password [redacted]). (e.g., mosquitto_sub -h buzz.0x20 -v -t "tele/sonoff/#") while the device is first booted.

You will see:

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"}

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 8E52C7/4807.

For raw ESP8266 devices (such as a wemos), go to sonoff-4807.0x20 (replacing the suffix with the second part of the label), go to "Configure/Configure module", set the device type to "18 Generic", then go back to that menu and configure the pins as desired. Note that, in order to get separate outputs per button/switch, you need to put a relay the same channel as the button. (shakes fist at cloud)

I found the following messages useful:

# 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 DVS_1141BC

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