Thanks for your inquiry, we appreciate your contact regarding this matter!
I would recommend another solution here. A lot of Sensors have a "divide" option already implemented. To use this, please switch to the sensor overview and open the specific channel settings by clicking on the corresponding gauge. On the top you can set the "Scaling Multiplication" and "Scaling Division".
If this is not available you can still work with the factory sensor. Please use the following formula in the "Channel Definition" section:
#<ID for this channel>:<Name of this channel>
You can also get some more information about the factory Sensor in this link.
