time_trigger does not work reliably for "x seconds before midnight" #330
Description
I want to collect the daily energy meter values (absolute and daily values in / out) and wrote a function for that:
sensors_daily = [
{"name": "sensor.energy_meter_energy_in_kwh", "format": "%7.1f"},
{"name": "sensor.energy_meter_energy_out_kwh", "format": "%7.1f"},
{"name": "sensor.energy_meter_energy_in_daily", "format": "%4.1f"},
{"name": "sensor.energy_meter_energy_out_daily", "format": "%4.1f"}]
sensors_monthly = [
{"name": "sensor.energy_meter_energy_in_kwh", "format": "%7.1f"},
{"name": "sensor.energy_meter_energy_out_kwh", "format": "%7.1f"},
{"name": "sensor.energy_meter_energy_in_monthly", "format": "%5.1f"},
{"name": "sensor.energy_meter_energy_out_monthly", "format": "%5.1f"}]
sensors_yearly = [
{"name": "sensor.energy_meter_energy_in_kwh", "format": "%7.1f"},
{"name": "sensor.energy_meter_energy_out_kwh", "format": "%7.1f"},
{"name": "sensor.energy_meter_energy_in_yearly", "format": "%6.1f"},
{"name": "sensor.energy_meter_energy_out_yearly", "format": "%6.1f"}]
@time_trigger("once(midnight-30s)")
def write_at_midnight():
dt_now = datetime.now() #+ timedelta(days=-1) # for the day before
write_sensors_to_file(dt_now, dt_now.strftime('/config/logs/%Y-%m-energy.log'), sensors_daily)
if is_last_day_in_month(dt_now):
write_sensors_to_file(dt_now, dt_now.strftime('/config/logs/%Y-energy.log'), sensors_monthly)
if is_last_day_in_year(dt_now):
write_sensors_to_file(dt_now, '/config/logs/energy.log', sensors_yearly)The function works in general, but is not triggered every day:

I have no idea how to solve it. Right now I changed the trigger to @time_trigger("cron(0 0 * * *)") to check if this is running every day, but here I have to compute the daily usage since the values are zeroed at midnight...
