Temperature and ambient light data

I am trying to access the temperature data that the T1000-E collects. My understanding is that I must enable it in Settings/Telemetry Config/Sensor Options and then I should see it in the Environment Metrics Log, but the latter remains grayed out. Is there more I need to do to see this data?

If the sensor uses a specific communication protocol (e.g., RS485, Modbus), verify that all settings (baud rate, address, parity, etc.) match between the T1000-E and the sensor.
