you are right something that does not change value and receives data continuously changes only in last-updated but does not change in last_changed, right?
That’s better! thank you!
{# Trastero Temperatura #}
{{
now() - states.sensor.battery_158d0001e89657.last_updated >= timedelta (hours=4)
and
now() - states.sensor.humidity_158d0001e89657.last_updated >= timedelta (hours=4)
and
now() - states.sensor.temperature_158d0001e89657.last_updated >= timedelta (hours=4)
}}
Seriously, I know you didn’t answer my question, whether you understand/Know what the Code, you got served does, that´’s fine with me
Then i provide you Hint’s,Tips, And links To The Most Basic INFO, EXAMPLES RTFM
Stop Asking more questions in this Topic
Start Reading The Docs, or Don’t ADD Another CARD, If you Dont want to read about What you DO, Or want to Do
It’s Kind of like the “Last_Changed VS Last_Updated”
You get “Updated” with Served “Solutions” But You never Change !, Before you start To Read
the difference between Last_Changed VS Last_Updated I read it here:
about the code…
{# Trastero Temperatura #}
{{
now() - states.sensor.battery_158d0001e89657.last_updated >= timedelta (hours=4)
and
now() - states.sensor.humidity_158d0001e89657.last_updated >= timedelta (hours=4)
and
now() - states.sensor.temperature_158d0001e89657.last_updated >= timedelta (hours=4)
}}
is a TRUE or FALSE template.
That is, if any of the entities in the device has not been updated for more than 4 hours it will return a TRUE. It calculates this by taking the current time and subtracting it from the time of the last update.
There are 3 conditions joined by an AND so that if one of them is FALSE it returns FALSE.
So the entire template will only be true when all the data has not been updated for more than 4 hours.
They are sensors that must be updated several times per hour, I use this template so that HA warns me that something bad happens with any sensor.
The problem comes from the fact that I have 40 sensors in the same automation, and all of them return the same warning message. And once I get the warning on the mobile that there is a sensor that does not work, I do not know which of the 40 is. So I need to create a panel to see which of the 40 I have is the one that does not update.
that’s why I was asking if I can make a list similar to this one showing the last update time of my sensors?
if you want help figuring out why that is erroring out, please post that yaml that’s erroring. i don’t think the things you just posted were the ones causing the error from that screenshot, right?
Sorry that you’ve followed my recommendation but I have just dumped this method of checking sensors altogether and am using uptime kuma so that I’m alerted of when the sensors come back online too
This is what I’m doing … create sensors in configuration.yaml
