I just flashed Tasmota on to three Sonoff S26’s without any soldering. I did need a USB to serial adapter to connect to the serial and power pins - I got one that included an ESP-01 so I knew it should work [0]. I also needed some bits of wire and crocodile clips, but that's all. The S20 is easier by all accounts, but I didn't know that until I'd already got the S26's. Having three to flash, I was motivated to figure out a solution that didn't involve soldering.
