Use pulse counter to calculate rps for anemometer

Hello, I have the Eltako WS anemometer connected to my esphome to measure the outside wind speed. I’m using the formula on this website to calculate the wind speed: v [km/h] = 1.761 / (1 + rps) + 3.013 * rps What I’m not sure is if I’m calculating correctly the RPS from the pulse counter. The wind sensor returns 4 pulse for a full spin and I want to get “a live” measure so I can control my awnings when the wind is too strong. I’m converting the pulses per minute to rps like this: pulses / 4*…
