Hi
I’m relatively new to HA and MQTT and I’m hoping someone can point me in the right direction to help me solve an issue I’m getting with mqtt based sensor. I’m using an ESP32 device with ESPHome MQTT to count the pulses on a power meter and sending total energy imported messages. In that location I’m also running a RPI with Mosquitto that is connected to HiveMq cloud. HA at home is running the MQTT integration connected to HiveMq.
I’m getting occasional data glitches that causes my sensor template to pick up what looks like an earlier mqtt message. When the glitches occur, it matches the the data point just prior to the previous glitch as shown in the charts below.
Here are code snippets, please let me know if I’m missing anything.
ESPHome device:
mqtt:
topic_prefix: power-meter
broker: 192.168.1.233
username: ""
password: ""
discovery: true
birth_message:
topic: power-meter/status
payload: online
will_message:
topic: power-meter/status
payload: offline
sensor:
- platform: pulse_counter
pin: 12
unit_of_measurement: 'kW'
name: 'Power Import'
accuracy_decimals: 3
filters:
- multiply: 0.06 # (60s/1000 pulses per kWh)
total:
unit_of_measurement: 'kWh'
name: 'Energy Import'
accuracy_decimals: 3
filters:
- multiply: 0.001 # (1/1000 pulses per kWh)
HA yaml config template:
mqtt:
sensor:
- name: "Grid Import Energy"
state_topic: "power-meter/sensor/energy_import/state"
unique_id: cb658877-f7f5-4061-914a-55f97b7ad7e9
state_class: total
device_class: energy
unit_of_measurement: "kWh"
I would appreciate any clues to what might be causing the glitches and why it’s picking up that specific value when it happens.
Many thanks,
Bruno
