Hey, do you want to update your Tasmota firmware on your energy meter? No problem! Here I'll show you how you can easily do it yourself. Let's get started!
Step 1: Access the web interface
Connect to your power meter and open the IP address of your ESP32C3 device in your browser. You will land on the main menu, which looks like this:
-
Tasmota main menu : There you have buttons like "Configuration", "Information" and "Firmware Upgrade".
Step 2: Select firmware upgrade
Click on "Firmware Upgrade" . Don't worry, this is exactly the right button to update the firmware.
Step 3: Select firmware
Now you have two options:
-
Upgrade via web server (OTA URL) – WARNING: NEVER DO THIS!
-
Upgrade via file upload – that's exactly what we do!
First, download the appropriate firmware file to your computer (e.g., tasmota32c3.bin ). Click here to download the file. Then, click "Choose File" and select the file.
Step 4: Start the upgrade
Have you selected the file? Then click "Start Upgrade" . The firmware will now be uploaded and installed. This step will take a few seconds.
Step 5: Switch to the Safeboot partition
During the update, you'll see the message "Switching to safeboot partition..." . This means your power meter is ensuring everything is working correctly. Relax and let it do its job.
Step 6: Upload successful
If everything worked, you will see the message "Upload Successful" . Your electricity meter will now restart automatically. After that, you can go back to the main menu and make sure that everything is running smoothly.
