<![CDATA[How to divide or multiply a SNMP Value]]>some controllers send values that are wrong, because the value came without decimal point, just we have two options:
Divide for 10 or multiplicate for 0,1

Please i need the script expresión to get the real value

Soon We will start checking what happen with this controller and them kind of SNMP Data.
Again, thanks for Your support

Doesn't seem like the actual polling for data would be different for the different data types, The only part that is very concerned with the data type of the point is the variableToValue and valueToVariable functions but both of those should be able to handle a Gauge and Numeric. I shared with you the variableToValue function before: https://forum.infiniteautomation.com/topic/3887/snmp-host-testing

Please could You tellme how to make a script.

Create a meta data source. Create a meta data point. Add the point you wish to divide by 10 into context,

return p.value / 10; //where p is the variable name of the context point

Yes you can definitely make a meta point and transform the value that way.

Coudl I make a meta data source and add a script that divide in 10 or multiply for 0.1???

You would have been clearly warned that you would lose the point value history of the multistate point when you changed it to numeric. Perhaps that could be improved.

But it sounds like those points are not polling. Do you have any events relating to this?

The Write Type could still be set to gauge and still permit you to set it (and it would transform it back with the multiplier and augend on the way out). So, it being Numeric will only affect things in Mango.

Thanks in advance

Is that point on the SNMP data source as a numeric data point? If so, there is a multiplier on the point's edit page:

If this is a meta point as relates to your other thread, you should be able to just add a multiplier into the script your wish to have this apply to, as with the multiply-by-20 you requested in the other thread.
