I am reading several 1wire temparature sensors with a Raspi 3 with this node:

> A Node-RED node to read a 1-wire temperature sensor

I wanted to start a heater when temperatures below 0 °C are reached.  
But I realized, that the min value is always 0.  
I don't know, how to contact the author @robquads.

As a workaround I read the "file" `/sys/bus/w1/devices/28-000005fa6d46/temperature`  
and devide the output value / 1000.

It doesn't appear to have a github repository, which would be the usual place to submit an issue. I would generally not use a node that is not on github (or somewhere similar) unless there was no alternative, and there are several alternatives in this case I think.

you can check who registered it with npm and send a polite email asking if they want to fix it etc... `npm owner ls node-red-contrib-1wire`

That Node is not updated for 6 years.

You can try the other nodes that are update on a later date.
