Wemos D1 Mini

Flashing Wemos with Tasmota

Follow these steps to flash a Wemos D1 Mini with Tasmota firmware and add the following lines at the end of platformio.ini:

[env:wemos-d1-mini]
platform = espressif8266
framework = arduino
board = esp01_1m
board_flash_mode = dout
build_flags = -Wl,-Tesp8266.flash.1m0.ld -DMQTT_MAX_PACKET_SIZE=1000
lib_deps = PubSubClient, NeoPixelBus, IRremoteESP8266, ArduinoJSON
extra_scripts = pio/strip-floats.py

; *** Serial Monitor options
monitor_baud = 115200

; *** Upload Serial reset method for Wemos and NodeMCU
upload_resetmethod = nodemcu
upload_speed = 115200
;upload_port = COM6

; *** Upload file to OTA server using SCP
;upload_port = user@host:/path
;extra_scripts = pio/strip-floats.py, pio/sftp-uploader.py

; *** Upload file to OTA server using HTTP
;upload_port = domus1:80/api/upload-arduino.php
;extra_scripts = pio/strip-floats.py, pio/http-uploader.py

From the Menu -> PlatformIO -> Run Other Target... (F7) and choose PIO Upload (wemos-d1-mini), this compiles tasmota and uploads the firmware to the Wemos device connected to usb.

Configure Tasmota for Wemos

Generic Module

In the Configuration -> Configure Module page, select Module Type: "18 Generic" (releases before 5.12.0 this was called "Wemos D1 Mini"). After Saving the settings, the WEMOS reboots with the Generic configuration. The first time you switch to "18 Generic" you will NOT see all the options as seen in the picture below YET. You have to save "18 Generic" first and when you go there again after the reboot you get the long table where you can change all the pin's parameters. These steps are confirmed to also work with the Wemos D1 mini PRO v2.0.0.
