Alright - this is my current dashboard:
Grid Import Sensor History looks good:
Grid Export:
Solar Production:
Watermeter:
All sensors are MQTT sensors configured as Total Increasing
Only Grid Import and Export are coming from the powermeter over modbus but also configured as Total Increasing.
modbus:
- name: hub1
type: serial
baudrate: 9600
bytesize: 8
method: rtu
parity: E
port: /dev/ttyUSB0
stopbits: 1
sensors:- name: sdm630_total_power_import
slave: 11
address: 72
input_type: input
count: 2
precision: 2
data_type: float32
unit_of_measurement: kWh
device_class: energy
state_class: total_increasing
scan_interval: 1800 - name: sdm630_total_power_export
slave: 11
address: 74
input_type: input
count: 2
precision: 2
data_type: float32
unit_of_measurement: kWh
device_class: energy
state_class: total_increasing
scan_interval: 1800
- name: sdm630_total_power_import
So I double checked again - the history graphs of all sensors are correct - only in the dashbboard it shows wrong - I think there the statistic values are used - they are wrong - why I do not know:
So here for examle - Grid Import - all of the sudden at 4:10 am - the import was minus 64,34 - so a negative value…
Also the solar production (the PV is offline during night) the statistic shows at the same time a negative production:
