Record the battery status of a Renault Zoe and write to a database
To make this work, you'll need a computer running 24/7 to query the Renault API.
Once the queries are being stored in the database, it is simple to connect Grafana to it.
Use this query to show the charge level on a graph
SELECT
requesttimestamp AS "time",
'chargelevel' AS metric,
chargelevel::int
FROM vw_zeserviceslog
WHERE
$__timeFilter(requesttimestamp) AND
chargelevel is not null
ORDER BY 1,2
