* at each device restart (due to arduino library
* interrupt bug)
* * other tiny improvements
* Version 1.3 - Paolo Rendano
* * change flow measurement unit to m3/h to adopt
* in home assistant as standard measurement unit
* for V_FLOW
*
* DESCRIPTION
* Use this sensor to measure volume and flow of your house water meter.
