Firmware update
Update firmware wa-pi.jar:
First you have to download the Watt Analytics firmware via the following link (~17 MB): https://files.watt-analytics.com/wa-pi.jar
When the download is finished, transfer the file to the SmartPi e.g. with FileZilla or WinSCP. Use the user pi and transfer the file to the directory /home/pi.
Then you can activate the firmware. Connect to the SmartPi with “ssh pi@IP- your-SmartPi”. Then enter the following command
- sudo mv wa-pi.jar /usr/local/bin/wa- pi.jar
- sudo systemctl restart wa-pi.service
- journalctl -f -u wa-pi.service
In the terminal you should now see the following.
- Started wa-pi Java Service
- WaPiApplication – Version: x.y.z (as described in the mail)
- … INFO and WARN messages but no ERROR messages
Installation
Prepare the SD card for the SmartPi:
ATTENTION: all data on the SmartPi will be lost, please back it up beforehand if necessary.
First you need to download the Watt Analytics SmartPi image via the following link (~4 GB): https://files.watt-analytics.com/wa-pi.dmg.zip
When the download is finished, unpack the zip file on your hard disk.

Firmware Update
iWattMeter firmware:
- Download the latest version of the iWattMeter firmware via this link (~1.3 MB): https://files.watt-analytics.com/iwattmeter_v2.1.35.bin
- Find out the local IP address of your iWattMeter based on all addresses in your WLAN router or use the Advanced IP Scanner application. Connect your computer to the same WLAN as the iWattMeter. You can find out the iWattMeter IP address based on the MAC address which has the same 6 characters at the end as the iWattMeter’s device ID (printed on the iWattMeter). If a name is displayed, search for ‘Espressif Inc.
- Open the OTA upload form in the browser: “http://iwattmeter- ip/ota/upload”. Example: if the IP address of the iWattMeter is 192.168.1.10, then the upload link is: http://192.168.1.10/ota/upload
- You will see a page similar to this:
- Click on the “Choose File” button and then on the “Update” button.
- Watch the upload process in the lower left corner of the browser.
- When the update is complete, the browser will display the following message: {“id”:0, “message”: “ok”}. If an error message is displayed, switch the iWattMeter OFF and then ON again, wait until it is connected to the WLAN again (approx. 30 seconds) and repeat the OTA upload.
- If the upload was successful, switch the iWattMeter OFF and ON again.
