BME280 connected on the I2C port, so far so good.

ok... not getting the data on the webpage (works fine in Ekos).

Doesn't seem to work in Ekos now
 

For some unknown reasons it started to work...

however the weatherradio.html isn't showing any data at all

An interesting observation:
it works with -v but not without

I am wondering why the DHT is being pulled while it's not configured on the board.

# rrdtool fetch sensors.rrd AVERAGE -s -1d -r 1h
BME280_Temp BME280_Pres BME280_Hum DHT_Temp DHT_Hum MLX90614_Tamb MLX90614_Tobj TSL2591_Lux

That's OK. The RRD file contains columns for all supported sensors, not only for the used ones.

Regarding the problem above with the -v flag - hm, strange, never seen. Try to use the debugger pdb.

I will try the pdb to debug, however I do not understand why the weatherradio.html returns nothing while the sensordata.html does.

weatherradio.html and sensordata.html have different RRD files as data source.

yes, the weather.rrd does not seem to be populated correctly, and that gives you an "empty" json file after so it's not showing anything on the webpage.
