Help with Pulse Meter unexpected reset

ESPHome
1

Hi,

I have set up a NodeMCU and TCRT5000 sensor with ESPHome to monitor our power consumption on a Ferraris Energy Meter. For one day it looked promising - the measurement was very accurate. Until all of a sudden the total counter dropped to zero:

Can anyone help me with finding the reason? Could this be due to an unexpected reboot of the esp? If so, how can I check the uptime? Maybe it lost the WIFI connection? Or did I screw up the configuration? :

esphome:
  name: nodemcu01

esp8266:
  board: nodemcuv2

# Enable logging
logger:

# Enable Home Assistant API
api:

ota:
  password: "lalalala"

wifi:
  ssid: !secret wifi_ssid
  password: !secret wifi_password

  domain: .myhome.domain

  # Enable fallback hotspot (captive portal) in case wifi connection fails
  ap:
    ssid: "Nodemcu01 Fallback Hotspot"
    password: "lalalalala"

captive_portal:

  - platform: pulse_meter

    device_class: power
    state_class: measurement
    unit_of_measurement: "W"
    internal_filter: 40ms
    internal_filter_mode: PULSE
    timeout: 20min
    filters:
      - multiply: 800
    total:

      unit_of_measurement: "kWh"
      accuracy_decimals: 3
      filters:
        - multiply: 0.0133333

Thanks in advance!!!

Will answer my own question: The reason was the bad wifi. I switched to a Wemos D1 Pro and the problem is gone…
