Are you doing Bluetooth proxy with the esphone version?

@Budget-Seat, it would be good to edit your original post as with the latest version of Tasmota the process no longer works. Converting to Tasmota is fine but if your end goal is to run ESPHome on the Shelly device then you only get one opportunity to load an ESPHome firmware image. Loading a ESPHome image via the Tasmota web console is fine, and the ESPHome firmware runs as expected. However, after that all OTA updates using ESPHome fail. If you initially flash the ESPHome image via serial then subsequent OTA updates via ESPHome work as expected.

Hello, I’m new to ESPHome and i have a question. Do esphome (or tasmota) support on-device local scripting (javascript running on device) like in Shelly firmware?
It’s for me very useful feature, quite robust and stable for me. And I think that makes Shelly devices very attractive.
ESPhome can be used so the device works automatically, so yes.
But it’ll be yaml with lambda…not java…
Tasmota can do similar, but I find the code comprehensive…
Thank you, @aceindy, for your response. After researching the scripting capabilities of the ESPHome firmware, I have come to the conclusion that it may not be as user-friendly for both developers and users as the scripting options available through the web interface of the Shelly firmware or the use of the VSCode plugin Shelly for writing and debugging JavaScript scripts on Shelly devices. Given this, I have decided to stick with the Shelly firmware and not pursue flashing ESPHome or Tasmota. I appreciate your help!
Hey all, I just tried to flash several shely plus 1. Long story short
- OTA using Tasmota don’t work
- You have to use UART and best way how to connect use striped CAT5 ETH cable pairs
- You have to compile localy
Long story - ESPHome on Shelly plus 1 — flashed | by Jiri Stepan | May, 2024 | Medium
Hi @jiristepan I have tried to flash the shelly plus 1 based on your guide and I am stuck on boot loop, the flashing works, but after the board starts it tries to initialize WiFi or something like that and than restarts. Any idea what could be wrong? I have tried 2 relays with same result.

Photos of the device
I got it working, actually it was working all the time. The problem was that my usb adapter which I used for flashing did not supply enough power to the device which caused reboot. If someone would face same issue watch for Brownout detector was triggered this means that the device was restarted because it was not getting enough power. When I connected the flashed device to main voltage it started correctly.
Hi Pieter,
I am half-way stuck with your approach.
I have flashed the Shelly to Tasmota and followed all the steps from the link, you provided.
As a result, I now have a recent Tasmota 14.1 version configured with the Safeboot partition introduced in Tasmota 12.x releases.
But now looking at the 2nd link, I see there a huge hint that flashing from Tasmota to ESPhome would not be possible because of the safeboot boot partition.
How have you accomplished this?
BR, Marcus
