I found chrontext, which describes itself as 'SPARQL-and Apache Arrow-based high throughput access to time series data residing in an arbitrary time series database which is contextualized by a knowledge graph.'
It lets you write a query which first queries a knowledge graph to find e.g a list of sensors, and then queries the timeseries database for the actual timeseries.
Quite a cool concept, and it made me wonder if there are other similar systems out there?
