Hello,
On cold water flow meter is one impuls output (which give 1 impuls for each 1 liter).
How can be possible
1. To measure such water flow with Shelly device (which can count the pulses).
2. How can be possible to show in graphical interpretation instead e.g. /celsius degree or watt/ the /Liter or m3/? Additionaly setable ratio will be helpful (becuase are exist more solutions, e.g. 1Liter=1imp, 10Liters=1imp, etc.)
3. Wifi connection will be required. Connect to 230VAC or battery is preferred (one is enough). Installation to water shaft.
Thanks in advance.
