Well folks i’m frustrated and tired. Spent two days researching and trying to build this an i got extremely close but failed
My goal is to use a boolean switch and helper time field to track medications. My son takes meds 3 times daily about every 4 hours. I want to set a notification system for the family that tracks that last time the meds were taken and remind us via notification system for the next time.
I have a system in place and rebuild this new one where everything is working with the exception of being able to enter a time manually and trigger the automation once we hit 4+ hours since the last time the time field was updated.
Right now the condition is as follows:
{{ now().timestamp() - as_timestamp(states.input_datetime.meds_time_entry.last_changed) > 14400 }}
But as you can see this is using the last change of when the field was updated, not the actual hour i entered into the field.
What i need to compare is current time, has it past 4 hours since the time that exists in the input_datetime field and then once it passes the 4 hours trigger. The challenge is the time field i created via Input_datetime was added as a time field only. I don’t want to have to worry about updating the date.
Hopefully this makes sense. Really appreciate any guidance here as i’m at the stage of giving up…
The right hand side takes the current datetime and changes its hour and minute to match the ones in your input_datetime. The result, which is a datetime object, is advanced by 4 hours (by simply adding a timedelta object set to 4 hours). Now the right hand side is “meds_time_entry + 4 hours”.
The left hand side is simply the current date and time (as a datetime object). If the left hand side is greater than the right hand side, the template reports true. If used as a Template Trigger, it will trigger the moment the current time is 4 hours after the time set in meds_time_entry.
What scripting language does HA use? I’m struggling to find out how people know to use certain attributes etc when calling or looking for certain data. I never studied code but got into scripting for example with a game (ARMA Series) which had a wiki with all valid scripting calls. HA has a nice documented database of integrations but i don’t find anything where it digs deeper into these other attributes. I do use the built in Dev Tools but it doesn’t really share all these additional attributes…
