notificaions for engine on more than 5 hours

alhajq create an Engine hours saving job, deactivate all options except Save the counter value as a parameter in a unit message. Schedule the job to trigger every 5 minutes, starting from 00:00 of the next day.
Create a custom sensor using the parameter from the previous step, let it be enginehr. The final parameter should be enginehr/const3600, this is in order to convert seconds to hours.
Create another Engine hours job but now select Specify a new value of engine hours counter, h: 0. Shedule this job to trigger only once at 00:00.
So, the first notification saves the engine hours counter value (btw, counter should be set to Auto) into a dedicated parameter, the second one resets the counter to 0.

Next, create a notification that controls the custom sensor value out of range 0 to 5. The notification triggers once total accumulated value for the day exceeds 5 hours.

alhajq the sensor works fine. I barely see the value at the screenshot, but they are probably:
37816seconds÷3600=10.5044hours

Parameter displays seconds. I therefore suggested adding const3600 into the sensor, to convert seconds into hours.
