sunportal is a web based visualisation tool to display data of SMA solar inverters. It is based on the database of SBFspot and shows charts daily and monthly power production. It runs on a Raspberry Pi and can handle multiple inverters in one Speedwire or Bluetooth(R) network.
Inverters that do not support Speedwire or Bluetooth or that are not from the manufacturer SMA can be integrated through s0-bridge. s0-bridge also enables power consumption to be recorded by using electric meters with S0 interface.
Current features:
- Web based visualization of daily and monthly power production
- Displaying multiple inverters
- Translations: English, German
- Mail notification service for inverter disorders and lack of production
Planned features:
- Visualization of yearly power production
- Visualization of power consumption
- Validation of
config.yml
with JSON Schema - Configuration of sunportal via web interface
- REST-API, i.e. to integrate solar power plants into home automation applications
If you like my project and want to keep me motivated:
First install and configure SBFspot as described here, the SBFspotUploadDaemon is not required.
Also add a cronjob for SBFspot to run every 5 minutes. Execute sudo crontab -e
, choose your preferred editor and add the following line:
*/5 * * * * /usr/local/bin/sbfspot.3/SBFspot -finq -nocsv > /dev/null
After that install sunportal:
# install needed dependencies
sudo apt-get install git python3 python3-pip
# clone this repo
git clone https://github.com/philipptrenz/sunportal
cd sunportal
#install _sunportal
sudo pip3 install -r requirements.txt
All configuration parameters of sunportal get stored inside the config.yml
YAML file. To edit the preconfigured values copy the config.default.yml
and edit the config.yml
:
cp config.default.yml config.yml
nano config.yml
Under mail
you can enable the integrated mail notification service by adding an SMTP server.

sudo python3 sunportal.py
Open a browser and navigate to the IP address of the Raspberry Pi to see the website.
# add the bash script to the service folder
sudo cp scripts/sunportal.sh /etc/init.d/sunportal
sudo chmod 755 /etc/init.d/sunportal
sudo update-rc.d sunportal defaults
Now sunportal can be controlled as a service (sudo service sunportal status
) and it automatically starts on boot.
