Simple OTA firmware server for Tasmota devices

Firmware Server for Tasmota OTA

This is a simple server that serves Tasmota firmware to Tasmota devices for OTA updates.

NOTE: Do not run updates from within Arc browser. The "smart" feature to open the OTA tab in a side-by-side pane messes up the update process and can cause it to update twice, or possibly stall it in an unstable state.

Setup

pyenv virtualenv 3.10.13 tasmota
pyenv activate tasmota
pip install -r requirements.txt

Usage

Get minimal firmware from: https://ota.tasmota.com/tasmota/release/ Get TLS from https://github.com/tasmota/install/blob/firmware/firmware/unofficial/tasmota-tls.bin.gz

Put both in the firmware/ directory as tasmota-minimal.bin.gz and tasmota-tls.bin.gz respectively. Optionally, you can save the firmware with a version number appended to them, then symlink to the expected names. This way you can keep multiple versions of the firmware around in case you need to roll back.

Usage:

python server.py -d <net_iface>   (default: eth0)
# or
python server.py -i <ip_address>

Example:

python server.py -d wlan0
# or
python server.py -i 192.168.1.10

Then from within Tasmota, go to the firmware update page and use

http://<your_ip>:38266/tasmota-tls.bin.gz. This will check the TLS, see it's too big, OTA the minimal, then OTA the TLS.

Wish List

• Only store the firmware by version and detect unversioned requests, then serve the latest version.

I found this code by Gennaro Tortone on the Tasmota site but it was broken. I have cleaned it up and made it work with some additional changes, including this Readme and setup instructions for recent Python.
