Hi Mark.
Yes there is a way to migrate from ESPHome to Tasmota. I have just done this on all my ESP Plugs due to the device running out of space with the New Versions of ESPHome. But please be carefull. I did brick 2 of my devices. THIS IS AT YOUR OWN RISK. But on the plus side, this did give me a device to work with and Flash Via Serial to ensure the process before I went onto any more.
I did speak to Adam and he will be doing a Video on this at some point.
So the process I Finally followed is below.
- Enable the Web Server on ESPHome
- Download from Tasmota, the current Tasmota Lite version tasmota-lite.bin.gz (PLEASE READ NOTE BELOW)
- Open the Web UI and in the OTA Update browse to the tasmota-lite.bin.gz file and click Update. The device will reboot
- On your mobile device you should be able to a Wifi Network. Join this and add in your Wifi Details.
- Once the device is on the network. You should be able to browse to the device. (The Device will start with the Lite Firmware)
- You can now proceed to load the device via the full Tasmota Firware and Follow Adams Video to confgure the Tasmota device.
(DO NOT USE THE MINIMAL VERSION AS IT IS NOT DESIGNED FOR INITIAL FIRMWARE. USING THIS WILL BRICK THE DEVICE)
Thanks
Nathan.
