How to Reinstall PiPower 5

If PiPower 5 is not working correctly and you want to perform a clean reinstall, follow these steps:

1. Uninstall the current installation:

cd ~/pipower5
sudo python3 install.py --uninstall

2. Reinstall from source:

git clone https://github.com/sunfounder/pipower5
cd pipower5
sudo python3 install.py

3. Reboot the Raspberry Pi when prompted.

After reboot, verify the installation:

pipower5 -a
sudo systemctl status pipower5.service

Tip

If the ~/pipower5 directory no longer exists from the original installation, skip the uninstall step and go directly to the reinstall step.

Dashboard Shows “Database Required” or No Data

What you see: The Web Dashboard opens normally in your browser, but all data panels are empty or show “database required”.

What this usually means: This is rarely a hardware problem. In most cases, the InfluxDB backend has a configuration issue — a corrupted database, a missing bucket, or an expired token.

Check these, in order:

Check that the PiPower 5 service is running:
```
sudo systemctl status pipower5
```
If the service is not active, start it:
```
sudo systemctl start pipower5
```
Check whether the InfluxDB bucket exists:
```
sudo influx bucket list
```
Look for a bucket named pipower5 in the output. If it is missing, the database needs to be recreated.
Check the service logs for errors:
```
journalctl -u pipower5 -n 50
```
Look for error messages related to InfluxDB, such as:
- unauthorized or token — indicates an authentication token issue.
- bucket not found — the database bucket is missing.
- connection refused — InfluxDB is not running.

If InfluxDB itself is down, restart it:

sudo systemctl restart influxdb
sudo systemctl restart pipower5

Note

If InfluxDB was installed manually or migrated from an older version, configuration paths or authentication tokens may have changed. In that case, a clean reinstall of PiPower 5 (see above) will also reinitialize the InfluxDB setup.
