Currently I am using Meteorologisk and want to use the temperature data from it on my grafana dashboard but I am not sure how to make into a sensor.
assuming you use the influxdb integration already… take a look on template_sensor to create a sensor and read the data from the met weather component. The sensor data gets reported to your influx db.
Also looking for a similar feature ie storing essentially temperature and relative humidity from weather.forecast_myhome (from Meteorologisk institutt (Met.no)) to InfluxDB
Maybe @joewy can share such a template?
Looks quite similar to Reading weather.homeassistant's forecast from grafana
