Connecting InfluxDB add-on in Home Assistant OS to Grafana Cloud without extra hardware?

Configuration

Hi everyone,

I’m working on a Home Assistant project and could use some advice. My goal is to read data from the InfluxDB add-on in Home Assistant and visualize it in Grafana Cloud.

The challenge is that I’m running Home Assistant OS on a mini-PC, which means I can’t install extra software or use Docker like you would on a regular Linux machine. I also have Home Assistant Cloud (Nabu Casa) enabled, so I’m hoping to find a solution that works within these OS limitations.

From what I understand, Grafana Cloud supports InfluxDB, but normally you need either a public HTTPS endpoint with authentication or a Private Datasource Connect Agent. The issue is that the agent requires installing additional components, which isn’t possible with Home Assistant OS.

So here’s my question:
Is there any way to make the InfluxDB add-on in Home Assistant OS securely accessible to Grafana Cloud given these restrictions?

If I’ve got something wrong or misunderstood something, please feel free to correct me. Any tips, examples, or best practices would be greatly appreciated!

Hello alt-rune, by using a public IP, preferably with SSL and allowing a specific port on that public IP to go through to your HA instance, that should work.
Know that

  • It will be easier if you also have a domain name, but it isn’t required
  • The connection will very likely be slow as your data is local and every query from grafana needs to get all the information over that connection before it can show you anything
  • Ensure you have a username and password set on the influx DB, if you do not, everyone on the internet that accesses that specific port will have access to all the data you are storing.
