Home Assistant dashboard: Pientere tuinen

Here you can find my dashboard elements for the Dutch project “Pientere tuinen”. A project to monitor the diversity in gardens around the country and make people aware of changes they can make to improve their garden for better water management, temperature and bio-diversity.

All this data will be used by different parties to see what the current status in each corner of the country and how to act on the current climate changes.

My sensor

Garden owners who live in a municipality who work together with the project can subscribe, and if they fit in the project, they can join and get a soil sensor. The first part of the project is to first track the soil humidity and temperature in the gardens and to see what they can do with this data.

During the project more and more environmental data will be added for each garden to get a better overview of what has an impact on your garden experience.

The sensor works on a LoRa network. There is no need for a local setup. You get an account for an online dashboard to see your data.

For advanced users, like us, they also provide an api which you can use to integrate it on your own dashboard.

Scrape the data

To get the data you need to scrape the api endpoint.

When you joined the project you can read more details on your own account.

Dashboard

With this data in Home Assistant I created my own dashboard.

Used dashboard elements

These are the three basic Home Assistant elements I used.

History Graph Card	https://www.home-assistant.io/dashboards/history-graph/
Gauge Card	https://www.home-assistant.io/dashboards/gauge/

Gauge with the humidity

Humidity gauge

A Gauge to show if the soil humidity is in a correct range.
The values depends on your type of soil.

Static value sensors

Create a sensors with a static values to show a min/max/base line in the graphics. These values are based on clay ground.

See this private project link which exact values are for your soil.

Soil type and water levels

In this graph, you can see that each type of soil has its own levels when it’s good for plants to live on.
