this is no issue but a contrib: made a prometheus-exporter and a grafana dashboard

https://gitlab.com/morninstar_gitops/prometheus_52pi_ups_exporter.git

- it includes:
- a 52pi ups prometheus exporter since there was none, I created one
- prometheus
- grafana and a sleek dashboard

--00-- prometheus scraping the 52pi_ups_exporter is already configured, grafana is also having datasource of prom set in

- just clone and: 
```bash
docker compose up
```

Enjoy
