  1. Not the part after eWeLink_ as your device id.

  2. Use your favourite tool to look for the ipaddress. Port 8081 will be open

  3. run

curl http://<deviceIP>:8081/zeroconf/ota_unlock -XPOST --data '{"deviceid":"<deviceID>","data":{} }'

curl http://<deviceIP>:8081/zeroconf/info -XPOST --data '{"deviceid":"<deviceID>","data":{} }'
# output should be something containing "otaUnlock": true
  1. Download tasmota
curl http://192.168.86.48:8081/zeroconf/ota_flash -XPOST --data '{"deviceid":"1000e9e0f7","data":{"downloadUrl": "http://192.168.86.32/tasmota-lite.bin", "sha256sum": "c4c8347666c4fd1e412a11338fe4a599f8010d5eaa5418bacb43bbc3b5149dbd"} }'
shasum -a 256 tasmota-lite.bin
  1. Start docker nginx
docker run -it --rm -d -p 80:80 --name nginx1 -v ~/<path to your tasmota nin file>:/usr/share/nginx/html nginx
  1. update firmware to tasmota
curl http://<deviceIP>:8081/zeroconf/ota_flash -XPOST --data '{"deviceid":"<deviceID>","data":{"downloadUrl": "http://<HTTPserverIP>/tasmota-lite.bin", "sha256sum": "<SHA256>"} }'

  1. Connect to tasmota AP and set network credentials

  2. Find your tasmota flashed sonoffs ipaddress (probably the same as before) and open it in a webbrowser
