Negative temperatures (ie below zero) show as positive temperatures.

Node is: xod-dev/dht/dht11-hygrometer

Anyone able to lend a hand? I can’t even devise a software way of stopping the readout at zero (ie making it a thermometer with a lowest reading of zero) because every trick I try causes the display to happily start showing temperatures again as the numbers go negative (but are coming out of the DHT-11 XOD node as positive). So a displayed temp of ‘5’ can be ‘plus 5’ or ‘minus 5’! It seems a pretty grave deficiency of the node for this sensor.

As it is an official XOD node, any help on this one?
