As far as the Line Chart missing ‘Live’ and ‘Minute’ views, this is expected behavior for MQTT and LoRa devices on Cayenne at the moment. Raspberry Pi and Arduino devices not connected through the MQTT API should still have these tabs. This is due to a difference in how the data is stored in different databases on our back end.
