Good day folks. A friend of mine told me his Sonoff 4CH light switch recently stopped working. It wouldn't respond to any commands and would appear as offline. Not having done any major work on these home automation devices before, we both concluded the firmware got corrupted, so we set about to find a way to reprogram it.
It turns out these things have got a STM32 inside of it and an ESP32, so given the open-source nature of these components, there's a variety of different firmware and interfaces you can upload to them......in theory. Ideally, we wanted to use the original one...
