Add decimal separator to MQTT number

Setup, Configuration and Use Scripts & Rules
1

I got a MQTT topic which has a number without decimal sign.
Last 3 digits
So I have 1073568 but it should be 1073.568
Can this be done with javascript transform Regex? sorry I’m new to this

2

What does the number represent, in terms of units? For example, is it Watts, and you want kW?

Nevermind - found a solution
