Quick question about modifying values

[AshaiRey]

Is it possible to do some math on a value before storing it in the device string?
The reason i ask this is because i got a MQTT topic that sends me the uptime in minutes but it is getting a large number so i would like to store it as hours.
A <value> mod 12 would give me hours.
Is this possible and if so how do it do this?

You can do it using either the regular expression or the expression textbox. Section 6.2 of mcsMQTT.pdf shows text manipulation using regular expressions. In particular example #4 does a manipulation of a date that could be a starting point for what you want. There are also Expression functions in Table 3 that manipulate strings so you can extract parts of the string and perhaps convert to number if that is what you wish.

Thanks,
Section 6.3 presented the solution.
The payload is a value in minutes.
With $$PAYLOAD: / (60 * 24) i convert it to days. The HS device is setup to show a value with 2 decimals.
So the decimal part isn't exactly in minutes but 14.40 parts of a hour but i don't mind that detail.
Close enough for me.
