Hi,
I try to build a battery driven Water Meter. For it a have ordered me some ESP32_Bat_Pro devices from EzSBC. I want to track my water usage on the ZENNER ETKDI-N with preinstalled reed contact which counts ≥1L/Impuls. I connected it to the ESP between IO14 and GND.
The reed closes, when a Liter water passed the counter and opens again, when a new liter starts to pass the counter.
My first problem is, that the counting works not like I expect it. I had it already counting something, but it got not saved. I seams that ESPHome does not save the values from pulse_meter / pulse_counter (I tested both, but only got pulse_meter working) when deep_sleep is used.
WakeUp is working, when GPIO14 get connected to GND, but it seams to me, that there are also two other problems/questions:
- is a pulse also counted, when he wakes up, or get those pulses dropped?
- the ESP goes to sleep also when water flows
- Save the state of pulse_meter before deep_sleep - maybe its not available in ESPHome right now - like it was on ESPEasy
Can somebody help?
