Using windows 10 & Windows 11 (tested on Windows 11):
- Click on start and type Windows features click on “Turn windows features on or off”
- Make sure that both Hyper-V and Windows subsystem for linux are installed
- Click on start and open “Windows Store” and search for wsl ubunty
Current version Ubuntu 20.04 would take few minutes to install
- Once installed, click on start and type cmd to open command prompt
- Once in command prompt type: bash to start WSL
- System is ready, now Sonoff mini R2 needs to prepared
- Turn off mobile data on your cell phone!!! (you might get an error if it is on and WiFi is on)
- Put sonoff mini R2 into pairing mode (hold reset button for 5+ seconds) blue light should blink 3 times than pause, 3 times pause…..
- Open eWeLink app on you phone and do Pairing. Once device is paired, try to switch it on and off. Device should click. Make sure that this works, then proceed
- Delete device in eWeLink app, that will warn you that it will do factory reset (we need this)
- Once device is deleted from eWeLink app, put it in ioT mode – press reset button for 5+ seconds, this time we need continues blink. If you get into pairing mode, just press reset for another 5 second for ioT.
- Now there will be new WiFi SSID available Something like ITEPxxxxxx and some numbers
- Connect to it, default password is 12345678
- You should get 10.10.7.2 as IP address, device is on IP 10.10.7.1
- Use web browser to connect to 10.10.7.1 and use prompt to change Wifi settings (use your regular home WiFi SSID and password)
- Once changed there will be prompt that SSID configured successfully.
- Find out wat is IP address of sonoff miniR2 on your LAN ( I used tool called AdvancedIPScanner, it is free)
- Now back to WSL (see step 5.)
- Thanks to Nicholas J Humfrey, we have script that would do this for us
- Get script by typing:
curl -O https://raw.githubusercontent.com/njh/sonoff-ota-flash-cli/main/sonoff-ota-flash.sh
- Change mod on this script by typing:
chmod a+rx sonoff-ota-flash.sh
- Now we can use script to flash Tasmota, type:
./sonoff-ota-flash.sh –i ipaddresOfDevice (ipaddressOfDevice is addres we got in previos picture.)
- Script will run and you should get screen like on picture below, type Y to proceed once asked to “Proceed with flashing”:
- Now wait for couple of minutes, then check for new SSID TasmotaXXXXX
- Flashing is completed.
Specs:
- Sonoff Mini R2 – firmware 3.6.0
- Wifi needs to support 2.4Ghz connections
- Wsl version 2. (it should work on version 1, did not test)
Optional
- Postman can be used for manually flashing – refer to Sonoff API @ http://developers.sonoff.tech/sonoff-diy-mode-api-protocol.html (tutorial is coming in future).
