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.
