Irrigation not work

[aleeeee5]

Hi everyone,

I'm using the Irrigation-V5 integration, but the irrigation program is not starting automatically, even though all conditions seem correct.

Current Setup:
time.tempo_di_inizio → Start time is set to 15:40:00

switch.abilita_il_programma → Enable program switch is on

switch.abilita_la_zona → Enable zone switch is on

number.tempo_di_irrigazione → Watering time is set to a value > 0

number.tempo_di_attesa → Delay time is set > 0

number.ripetizione → Repetition count is ≥ 1

select.frequenza → Watering frequency is set to daily

switch.ignora_i_sensori → Ignore sensors switch is on

switch.irrigazione_outlet → This is the zone switch (off by default)

binary_sensor.irrigazione_stato → Water source status is on

binary_sensor.pioggia_sophisticated → Rain sensor, not blocking due to ignora_i_sensori

sensor.prossima_irrigazione → Next irrigation sensor stays unknown

As a result, the irrigation never starts

I found this error in the logs:

TypeError: '>' not supported between instances of 'NoneType' and 'datetime.datetime'
This happens in zone.py because the integration compares:

self.next_run.native_value > dt_util.as_local(dt_util.now())
But self.next_run.native_value is None, which causes the comparison to fail.

The integration fails to calculate next_run, which causes:

sensor.prossima_irrigazione to remain unknown

and the irrigation program never activates automatically

It seems the issue is related to start_time not being recognized properly as a valid input_datetime, or not being initialized.

Let me know if this is a known issue or if there’s a proper fix/workaround to ensure next_run is calculated and triggers the program.

Thanks!

Can you provide your diagnostic file:

Also the full snippet of the error from the log with line number/object etc.

The default operation is the Next Run is set based on the frequency. When a new program is configured this is calculated.

Are you using a sensor to set the frequency?
