Raspian with the latest updates and kernel. Pi3B+
I have been running a pi out in the greenhouse since last spring and I just noticed the temp/humidity DHT11 sensor stopped working.
I am using node-red with the node-red-contrib-dht-sensor lib. I just figured the sensor went bad so I ordered another and... woops the sensor is fine...
I have a spare Pi so I decided to try to get a spare DHT11 running on a fresh install.
Still no joy. Something must have borked in an update, maybe? Does anybody else have any DHT11's running?
Here is a simple debug flow for one.

Any advice on how to troubleshoot this would be greatly appreciated!
