negative temps

[nate8199]

I'm having issues with negative temperatures, they aren't reading correctly, and they don't work if I select the Fahrenheit option.

When you say aren't reading correctly can you provide a bit more information i.e. is it over/under reading by a lot, a little etc?

Regarding the Fahrenheit option - do you get any errors in your NodeRed logs?

I actually found another node I'm trying, node-red-contrib-ds18b20-sensor, along with a function to convert to Fahrenheit, it simplified my layout some this way also. I will try and set it up to provide a reading from both your node and this newer one.

I’ve had the same issue. Negative temps just come through as positive

The regex does not match negative numbers ie t=-1234 1Wire.js change data.match(/t=(\d*)/) to data.match(/t=(-?\d*)/) and it works.
