Using API with Openhab


#1

Just want to say Hello and thank you for the API from Switzerland. I’m using your API for my Smart Home Project with Openhab and our PV at home with 14 kwp.
Screenshot from today (using Influxdb and Grafana):

Would you like to share your API integration code for others to learn from? Your choice of distribution GitHub, GitLab, BitBucket, self hosting, etc.

Thanks very much for posting your feedback!

We plan on announcing some exciting features to our API before the end of the year which we’ll post about on these forums. :tada:

We appreciate any sharing of data, code and the like which better informs us how users are using the API.

Thanks again :slight_smile:

Hi @hippo_2 - that looks like a fantastic use of the solcast API and exactly what I’m trying to achieve with my system at the moment.

Is there any chance you’d be able to share how you brought the information into influxDB/openHAB? I’ve followed one of the worked examples on the InfluxDB website to try and get the overall concepts, but it would be great to see how you’ve actually implemented getting data from Solcast in to InfluxDB (then displayed in openHAB).

Thanks very much in advance!

Hi @joncknott , I started with this tutorial to setup Influxdb and Grafana working with Openhab.

Create a persistence-file “influxdb.persist”. After that I made a cache item with the URL

solcast.url=https://api.solcast.com.au/pv_power/forecasts?longitude=yourlongitude&latitude=yourlatitude&capacity=14000&tilt=17&azimuth=-174&install_date=20160901&api_key=yourapikey&format=json

Create a “items” file like that:
Number Solcast005 { http="<[solcast:300000:JSONPATH($.forecasts.[0].pv_estimate)]" }

In Grafana you have to create a new graph like that:

I hope this will help you with your project. Have fun!
