Need the device name visible on the Shelly device Web page.
Please post a screenshot from.

That would be „ProDimmer2PM“:

There is no update package available for this device from Shelly update server.
https://updates.shelly.cloud/update/ProDimmer2PM
To make a convert package I need infos from this package. As long there is no update is available no dice.

There are flash pin headers. If you can dump the installed firmware (8MB), and provide me the dump I could try to do too.

[justspacedog]

That would be awesome! How can I do the dump?

See https://docs.espressif.com/projects/esptool/en/latest/esp32/esptool/basic-commands.html#read-flash-contents-read-flash
You need hardware for. Recommended https://tasmota.github.io/docs/Getting-Started/

I have a serial interface somewhere, but we just moved and I don’t know where I put it… :/

I activated debugging on the WebInterface and found out, that the update URL uses the Identifier „ProDimmerx“:
https://updates.shelly.cloud/update/ProDimmerx

So the stable Firmware should be found under:
https://fwcdn.shelly.cloud/gen2/ProDimmerx/d6d452c462e2e60e7106ff8996c0ac6184c0ba984d96a5490f5adf9874b6ea4e

It’s a 2,2 MB Zip Archive. Can you work with that or do you need the dump?

[Jason2866]

The Firmware update package is enough to build a convert package. BUT i would not convert without a complete dump (backup) of the orig. firmware. Just the fact that Tasmota can be installed does not mean that it is usefull on this device.
If you have backuped (dumped) your Shelly firmware you can try
https://github.com/tasmota/mgos32-to-tasmota32/releases/download/v13.4.2/mgos32-to-tasmota32-ProDimmerx.zip
If it works Tasmota will start and the device gets bricked!! since there is no Autoconfig setup which does replace the locked Shelly bootloader.

So in any case if you try the convert package you have to reflash the orig. firmware afterwards (or Tasmota).

If it is similar to #17 it is not supported from Tasmota
