What user you use to install your software. As well some more information on your SBC. Which architecture you are using? 32 or 64 bit.

From install.sh
```nohighlight
USER_RUN_FILE=/home/pi/.bashrc
```
You will need to create a user named pi on the device…
or you could change it to
```nohighlight
USER_RUN_FILE=/home/dietpi/.bashrc
```
You did ensure you installed the prerequisites right?
```nohighlight
sudo apt-get install python-smbus
sudo apt-get install pigpio python-pigpio python3-pigpio
```
