I have configured a NodeMCU with an SDS011 and DS18B20 sensor. Both are configured but the 1 Wire DS18B20 on D7 (GPIO13) cannot be read -

Sending to sensor.community - SDS011

I have tried other code on the same board using the same connection and it works fine. There is no option to add the DS18B20 unique address so is this why it cannot be read ?
