So I have been a long time user of Shelly 1, I have about 20 or so, going back to hardware version 1.
Until recently they were all running Tasmota, because in those early days, that did what I wanted, and I just kept doing the same.
Currently Shelly firmware also seems to do what I want, but with a much more non-tech-user friendly interface
And I am thinking of reverting them all to Shelly OS
I know how to do that wired up to the TTL-Serial. I remember even saving an original image before I flashed Tasmota.
However, I would very much prefer doing it without having to climb up, on, under all the places I have mounted them, to remove them, flash them, and then climbing up,on, under those places again to put them back.
Shelly did not happen to make a Tasmota compatible "coming home" firmware? Some bootstrap OTA (Over the Air) minimised firmware that I can flash into Tasmota remotely, and that then allows allows me to flash proper Shelly firmware? Similar to Tasmota "minimal image" but for Shelly?
