A Chinese company named Tuya offers a free-to-brand turnkey smart home solution to anyone. Using their offer is dead-simple, since everything can be done by clicking through the Tuya web page, from choosing your pre-designed products or pre-programmed wifi-modules (mostly ESP8266) to building your own app. In the end, this has resulted in as they claim over 11 000 devices 'made' by over 10 000 vendors using Tuyas firmware and cloud services. In the following days, VTRUST and the German tech magazine c't decided to work together. Since reflashing devices using the ESP8266/85 is widespread among DIY smart home enthusiasts, we wanted to provide an easy way for everyone to free their devices from the cloud without the need for a soldering iron.
