# OpenDTU Logger Home Assistant add-on
|
||||
|
||||
OpenDTU logger adds detailed, long-term storage and visualisation of Hoymiles solar inverter metrics monitored with OpenDTU.
|
||||
|
||||
|
||||
|
||||
## Installation instructions
|
||||
|
||||
These instructions contain 3 steps:
|
||||
|
||||
1. This add-on requires a PostgreSQL database, optionally with TimescaleDB support. In this example, we'll Expaso's TimescaleDB add-on in order to store data.
|
||||
2. Then, we install OpenDTU Logger to connect to OpenDTU and record inverter data into the database.
|
||||
3. Finally, we setup Grafana to visualise the data recorded by OpenDTU Logger.
|
||||
|
||||
### Install Expaso's TimescaleDB add-on
|
||||
|
||||
Install Expaso's TimescaleDB add-on by adding <https://github.com/Expaso/hassos-addons> to the add-on store and installing TimescaleDB.
|
||||
|
||||
After installing TimescaleDB, go to Configuration. Click the three dots in the top-right corner and select "Edit in YAML". Then, make the following changes:
|
||||
|
||||
- Add opendtu_logger to `databases` and `timescaledb_enabled` like so:
|
||||
|
||||
```yml
|
||||
databases:
|
||||
- homeassistant
|
||||
- opendtu_logger
|
||||
timescale_enabled:
|
||||
- homeassistant
|
||||
- opendtu_logger
|
||||
timescaledb:
|
||||
telemetry: basic
|
||||
maxmemory: 512MB
|
||||
maxcpus: 4
|
||||
max_connections: 50
|
||||
system_packages: []
|
||||
init_commands: []
|
||||
retry_upgrade: false
|
||||
```
|
||||
|
||||
Save the configuration, go to the "Info" tab and start TimescaleDB.
|
||||
|
||||
### Setting up OpenDTU Logger
|
||||
|
||||
With the database initialised, we can now setup OpenDTU Logger. Add the [add-on repository](https://git.hollander.online/energy/home-assistant-addons) using the [instructions](https://git.hollander.online/energy/home-assistant-addons) provided. Then, click "Install" to install this add-on. Go to "Configuration".
|
||||
|
||||
- If you're using Expaso's TimescaleDB add-on, the `db` setting will **not** require any changes.
|
||||
- **In the `opendtu` field, enter the *IP address* or *hostname* of your OpenDTU.** E.g.: `192.168.1.5` or `opendtu.local`.
|
||||
- In `tz`, enter your timezone. The default is "Europe/Amsterdam".
|
||||
- Optionally, if you don't want to use TimescaleDB, disable `timescaledb`.
|
||||
|
||||
Save the configuration, go to the "Info" tab and start OpenDTU Logger.
|
||||
|
||||
Check the "Log" page. If the setup is succesfull, it should contain a mesasge stating: `OpenDTU Logger has been successfully initialised. Starting data recording...`.
|
||||
|
||||
### Setting up Grafana
|
||||
|
||||
From the Home Assistant Community Add-ons repository, install Grafana. Click "Start" to start the add-on and then click "Open Web UI".
|
||||
|
||||
- In the top-left corner, click the three bars (open menu) -> Connections.
|
||||
- Using the search box, enter `PostgreSQL`. Click the resulting "PostgreSQL".
|
||||
- In the top-right corner, click "Add new data source"
|
||||
- Use the following settings
|
||||
- Name: `opendtu_logger`
|
||||
- Host URL: `77b2833f-timescaledb`
|
||||
- Database name: `opendtu_logger`
|
||||
- Username: `postgres`
|
||||
- Password: `homeassistant`
|
||||
- Version: `16` or the closest version to it.
|
||||
- TimescaleDB: Toggle the switch to enable TimescaleDB support.
|
||||
- Click "Save and Test". A "Database Connection OK" message should appear.
|
||||
- In the top-right corner, click the `+` sign, "Import dashboard".
|
||||
- Go to <https://git.hollander.online/energy/opendtu-logger/src/branch/main/grafana>
|
||||
- In this folder, a number of sample dashboards is available.
|
||||
- For a complete overview of all collected data
|
||||
- For English, use `PV.json`.
|
||||
- For Dutch, use `Zonnepanelen.json`.
|
||||
- Click the dashboard you want, and then "Raw".
|
||||
- Copy and paste the text into the "Import via dashboard JSON model" box.
|
||||
- Click "Load".
|
||||
- In the `energy` field, select `opendtu_logger` as the data source.
|
||||
- Click import. You should now be able to view the data, collected by OpenDTU Logger and stored into TimescaleDB.
|
||||
- Feel free to try out the other dashboards as well.
|
||||
|
||||
## Configuring OpenDTU
|
||||
|
||||
In order for OpenDTU Logger to work properly, it is required to ensure the following OpenDTU settings are used.
|
||||
|
||||
- Within OpenDTU, go to `Settings` -> `Inverter settings` (<http://YOUR_OPENDTU_IP_ADDRESS/settings/inverter>).
|
||||
- For each inverter in the inverter list, click on the pencil (Edit inverter) and go to `Advanced`.
|
||||
- Enable `Zero daily yield at midnight` and `Clear Eventlog at midnight`.
|
||||
- Click `Save`
|
||||
- Repeat this procedure for every inverter.
|
||||
|
||||
By default, OpenDTU sends data every 5 seconds. This can be adjusted by changing the "Poll interval" setting in <<http://YOUR_OPENDTU_IP_ADDRESS/settings/dtu>.
|
||||
|
||||
## Security notice
|
||||
|
||||
Using the aforementioned steps, you should now have a working OpenDTU Logger setup. However, it is important to keep your data safe. [Expaso recommends](https://github.com/Expaso/hassos-addons/tree/master/timescaledb#usage) changing the default postgres `homeassistant` password. I recommend following their recommendation and also installing the pgAdmin4 add-on using the [instructions](https://github.com/Expaso/hassos-addons/tree/master/pgadmin4) they provide. In case you're doing this after setting up OpenDTU Logger, remember to also update this password in the OpenDTU Logger config and the Grafana data source connection settings.
