Ok
Go to Paper UI. Click on Configuration. On the left side of the screen click on Things. This will bring up a list of things you have added. Find the THING that you want to edit. (ex: I clicked on Office Comfort on my screen). Click on the pencil icon on the right. This should bring up the screen showing the channels connected for that THING. Click on the pencil icon on the right to edit the information for that channel. When the Configure channel screen pops up you will see the words SHOW MORE on the bottom left of that screen. Click on those words and it will show more as shown below by the red arrows. Mine indicates SHOW LESS because I have already clicked on SHOW MORE. Then enter your temperature format command in the Outgoing value format line.
Outgoing value format
Format a value before it is published to the MQTT broker. The default is to just pass the channel/item state. If you want to apply a prefix, say “MYCOLOR,”, you would use “MYCOLOR,%s”. If you want to adjust the precision of a number to for example 4 digits, you would use “%.4f”.
