Connect Water Flow sensor to Smart Implant/Universal Binary Sensor

Hello,

Sorry but those devices are not designed to count pulses - there is no way to do so.
Frequency of those pulses will be to high to report them directly to the Gateway so it is not possible.

If you want to connect water flow sensor to Smart Implant (or RGBW in this case) you will need 0-10V DC active or passive sensor (I definitely suggests active one).

Regards,
Michał

... or if you have already that Water Flow Sensor and can't replace it with one which deliver 0-10V output, you might try "frequency to voltage 0-10V converter", ebay 10EUR or so.

Hi..
probably the basic question is:
Do you want to measure the current (m3 / hour or similar) using "frequency to voltage 0-10V converter" from Tinman's post,
or cumulative (number of pulses x for example 0.01m3 according to the given meter?).
You can use SI here, ... but ensure reliable reading.

SmartHomeEddy referred to the thread where this matter was resolved.

By the way, most pulse meters work so that the pulse per unit is about 0.5-1sec.
The SI can handle this and send it to the HC3, but if there is an interruption or delay in the transmission or processing of information, when the pulses will be more frequent, it is necessary to choose another path (local reading and transmission of measured values - M-Bus, Modbus, .. )

eM.
