question

Hello,

I have a similar question, i think this is the good value to obtain the daily consumption but the problem here is that there is no reset of this value each day.

If you restart the Venux GX à 00:00 it will be OK but i search a way to to this automatically.

https://community.victronenergy.com/questions/65203/reset-log-daily-in-venus-gx.html

Tell me if you find the way to do that.

I found a way (but not really clean) to have the counters at 0 each day.

I just add a line to the Venus GX crontab to reboot at midnight.

#reboot everay day at 00:00
00 22 * * * root /data/rebootatmidnight.sh

Here is the content of the rebootatmidnight.sh file :

root@beaglebone:/data# cat rebootatmidnight.sh
#!/bin/bash


cd /sbin
reboot

There is 2 hours of lag due to the time zone of the Venus GX here it's 22 p.m for midnight in my home location.

I still waiting for a better solution, for example just restart a service or reset a log file to do the same thing.

I saw the log reset is possible for the generator option. Maybe it will be the same for the main consumption logs.

Daily kWh consumption is extremely useful in HA (Home Assistant), I searched the available Victron Modbus registers and couldn't find one that contained the information required, only total consumption. After some creative thinking I figured out how to use two HA Helpers and two Automations to store "sensor.discharged_energy" in a variable at midnight (input_number.discharged_energy_at_midnight), then using that variable to calculate a second variable (input_number.ac_today) that represents the daily discharged energy "AC Today" at 10 second intervals .

Automation 1 - store "sensor.discharged_energy" into Helper entity/variable "input_number.discharged_energy_at_midnight " at midnight .

1. service: input_number.set_value
2. data:
3. value: '{ { states(''sensor.discharged_energy'') |float |round(1) }}'
4. target:
5. entity_id: input_number.discharged_energy_at_midnight

Automation 2 - calculate "input_number.ac_today " alias (AC Today) entity/variable.

1. service: input_number.set_value
2. data:
3. value: >-
4. { { ((states('sensor.discharged_energy') |float -
5. states('input_number.discharged_energy_at_midnight') |float ) | round(1)) }}
6. target:
7. entity_id: input_number.ac_today

Maybe someone can improve on this approach, suggestions are welcome :)
