- TUYA-CONVERT
- https://github.com/ct-Open-Source/tuya-convert
- TUYA-CONVERT was developed by Michael Steigerwald from the IT security company VTRUST (https://www.vtrust.de/) in collaboration with the techjournalists Merlin Schumacher, Pina Merkert, Andrijan Moecker and Jan Mahn at c't Magazine. (https://www.ct.de/)

- PLEASE READ THIS CAREFULLY!
- ======================================================
- TUYA-CONVERT creates a fake update server environment for ESP8266/85 based tuya devices. It enables you to backup your devices firmware and upload an alternative one (e.g. ESPEasy, Tasmota, Espurna) without the need to open the device and solder a serial connection (OTA, Over-the-air).
- Please make sure that you understand the consequences of flashing an alternative firmware, since you might lose functionality!
- Flashing an alternative firmware can cause unexpected device behavior and/or render the device unusable. Be aware that you do use this software at YOUR OWN RISK! Please acknowledge that VTRUST and c't Magazine (or Heise Medien GmbH & Co. KG) CAN NOT be held accountable for ANY DAMAGE or LOSS OF FUNCTIONALITY by typing yes + Enter
