Rain Gauge - How to total / increment reed switch

Hi there

I’ve modified my Oregon rain gauge and soldered wires to the reed switch which I’ve then connected to VIN pin and D8 pin on a nodemcu board and using ESPhome with the intention of it recording the amount of rainfall over time.

I’ve set it up using the pulse_counter platform however the issue is that the pulse_counter acts like a counter per minute giving you the number of times the switch is toggled in one minute but then resets to zero after a minute and starts counting again for the next minute, what I need is for it count each time the switch is toggled and increase it by that count so that I am then able to measure rain fall by hour, day, month, year etc…

Is there a way to count and store this information in Home Assistant?

I’ve searched the forum and have come across similar scenarios but haven’t really seen any examples of a reed switch being used to count, its either open or closed and doesn’t need to be accumulated.

Thanks in advance.
