I'm one of the maintainers of the opensource project https://github.com/mirko/SonOTA , however with the latest release there appears to be certificate pinning (or similar) happening. This means that users can only upgrade the firmware in the Sonoff devices if they open it up, and solder in headers.
Using this OTA method users could get all of the benefits of an open platform, without the the need to open up the device and solder etc.
Se hace imprescindible la opción a regresar a una versión anterior.
En todo caso, que se pueda desinstalar la APP e instalar la versión de firmware que pueda interesar.
Deben estar disponibles las diferentes versiones.
The option to return to an earlier version is essential. In any case, you can uninstall the APP and install the firmware version that may interest you. Different versions must be available.
Ive bought $300 worse of sonoff products and now I need to waste my time with soldering in order to update the firmware.
If you guys really care about security, please talk with tasmota maintaners and add their servers to the allowed firmware upgrade destinations.
This is ridiculous. Ive bought sonoff because everybody been saying that they are easy to flash with tasmota. Now I need to buy new hardware... Thank you sonoff
@itead - PLEASE support installing TASMOTA firmware over the air
Keep in mind that tasmota is already rolling out support for ota installation of custom firmwares for some newer devices with Sonoff DIY, where you just need to move a jumper, to be able to do it.
Yes, I've used it for my sonoffmini... but it's not available for latest firmware versions of sonoff basic.
I flashed two sonoff mini with tasmota firmware. I want back to itead firmware so I can use Ewelink. Can I do that?
Like many others here, I have purchased many Sonoff devices including Touch, Basic & Slampher and I want to continue to be able to build out the more automation in my home and purchase more from you. Friends are also impressed with my setup with earlier versions which I have managed to flash Tasmotta. I recently installed a number of Touch US panels for my lights and I'm disappointed I can no longer flash them with Tasmotta or similar open firmware.
I will no longer purchase further Sonoff devices and I cannot recommend to my friends unless you provide a way to flash custom firmware OTA. Please update your latest firmware to allow OTA install of open firmware or allow downgrading your firmware so that excellent projects like SonOTA continue to work.
Your products have been competitive from a price point of view, but this is a show stopper. I have already found alternate switch manufacturers running Tuya firmware which can be flashed OTA via https://github.com/ct-Open-Source/tuya-convert and I will continue to purchase their products instead of yours and recommend the same to my friends if you do not fix this issue.
BTW, new Sonoff devices have option to be flashed easily (not OTA, but...) through USB converter. And after you flash with Tasmota, you can flash them OTA anytime with new firmware. So, it is not a big deal anymore...
Thanks @Dejan, I realize that and I have flashed other Sonoff devices via USB converter, but this way is riskier, requires opening the device and more equipment, sometimes even soldering. Certainly only suitable for those capable or brave, so I also can't recommend Sonoff devices to general friends who do not have such skills or equipment.
In my case, the latest ones I bought are the touch light panels, I had them installed and wired believing I can flash them OTA later, not so, now I will have to have them removed again, flash them them, then reinstall them at great cost. Iin my country any such wiring work must be done by a licensed electrician. All these are barriers to entry and I think Sonoff should seriously reconsider their position on supporting OTA of custom firmware. Until this is supported, I will use alternate hardware that does.
