Changing unit and rounding of e.g. temperature notifications - Alpenskipper - 2017-09-06

Hi!

In notifications it would be great, if units could be changed (e.g. celsius) and rounded.

It looks strange in freeboard.

You can add a function node to do that, I don't use freeboard so you'll probably need to change msg.topic to something else.

var numInput = Number(msg.payload);
msg.topic = "Eng";
var T = numInput-273.15;
msg.payload = T.toFixed(1);
return msg;

Hello, I changed the units in freeborad in "value" or JS editor with this is comand:

datasources["node-red"][environment.inside.heating.temperature"].toFixed()-273

Thanks for the hints. But, for I am a Linux/ JS noob, I have no idea, where to edit...
Could you explain it for dummies, please?

if I remember correctly, it is modified where you have added the temperature, pressure, ... in freeboard.

you have to add the last part.
.toFixed()-273
If you do not find it, tomorrow I'll send you a screenshot

Great!
.toFixed(n)
worked perfect.
