In this video I grab my Ubuntu Laptop and using Sonoff DIY mode flash Tasmota on a Sonoff Mini. This is the 2020 updated version, flashing Tasmota 9.1.0 Imogene release. I have seen others do it with a phone and a windows box, but I have not seen it done with Ubuntu ans curl post commands. You can use this same method to flash ESPHome or other firmware’s as well in DIY mode. If you know my, it’s Tasmota 100%.
This will also work with Debian and other Linux Distros.
So dust off that old 2010 laptop that you no longer can use for Windows and give it a new life with Debian or Ubuntu, and give yourself an awesome tool for flashing ESP’s and maintaining your smarthome!
I also attached a web post that I used for reference here getting the curl commands correct. In that web post he shows other ways to do this flash if you are interested.
