This guide explains how to convert Shelly ESP32 and ESP32-C3 driven devices to Tasmota (no other firmware!)
The convert workflow provides a safe update. However, it is a risky operation to overwrite the bootloader. If something unexpected happens, it will probably render the device inoperable until it is recovered. To recover a failed convert, flashing Tasmota over a wired serial connection is needed.
⚠️ Needed⚠️ Update the device to the latest stable firmware (Internet access!!)- Download the name corresponding zip package for your device (See release section)
- Connect to your Shelly device via Wi-Fi or LAN
- Navigate to Settings > Firmware and drag & drop the convert "zip" in the firmware update area (do NOT update via URL)
- Click the Update button
- Device is updating, finished in 1-2 minutes
- If Shelly Web frontend is back after the update, repeat the steps above.
- The Web frontend does not react anymore now.
- Connect to the newly opened Tasmota Wi-Fi access point and add the device to your Wi-Fi (full Internet access needed).
- Configure the device using Tasmota Auto configuration. (Configuration > Auto-configuration > Select new auto-configuration) Select your device and hit enter. This replaces the locked bootloader (without this step device gets bricked with the next firmware update).
- Wait until the device is online again. Takes a few seconds
- Under consoles, open the Partition Wizard and start the Safeboot Conversion by hitting the button "Start Migration". The conversion will update to the latest Tasmota version too.
- Wait until the device is online again. Takes 3 - 5 minutes
- Optional: Use Partition Wizard to increase the Filesystem size to its maximum. This removes all obsolete files too.

If your Shelly device is not listed, please open an issue with a link to the Shelly Knowledge Base.
Or buy the device from my Amazon Wishlist and I will reverse engineer and confirm the device working.
I would like to thank Jason2866 for providing help with the custom Tasmota files and s-hadinger for the Berry code fixing startup of Tasmota.
