Lightning Strike Template - Newbie

Configuration
1

So I am trying to create my first simple template. If Lightning is > 10 miles from my house return ‘Far’ (because I do not care), else if Lightning is < 10 miles from my house it reports the distance and the time measured.


{% if ("sensor.weatherflow_last_lightning_strike_distance" < "10") -%}
  Far at 
{%- else -%}
  {{ states('sensor.weatherflow_last_lightning_strike_distance')}} at {{states('sensor.weatherflow_last_lightning_strike')}}
{%- endif %}

The template works however I cannot format the time to a readable time (ie. HH:mm). Also, how would I limit this template to only report lightning strikes in the past 60 minutes?

What is the state that this is showing now?

Maybe:

{{ states('sensor.weatherflow_last_lightning_strike').strftime("%H:%M") }}

It depends if it is a datetime object.

3

UndefinedError: ‘str object’ has no attribute ‘strftime’

The deviceclass of the sensor is

device_class: timestamp

Can you share thee actual state please, like I asked?

It may need this:

{{ as_datetime(states('sensor.weatherflow_last_lightning_strike')).strftime("%H:%M") }}

But I’m still just guessing without this information:

Perfect. Shows the time as HH:mm.

Any idea how to create a double condition so that it will only show the distance and time if the time has been in the last 60 minutes?

6

Are you sure this works as intended? this is a constant string comparison. You are missing the states() function.

7

I will have to wait for lightning to strike to find out. How would you write it to work?

8 
{% if (states('sensor.weatherflow_last_lightning_strike_distance') | float(0) > 10) -%}

So you don’t just use the sensor name but get that sensors state, convert it to a number that may have decimals and compare it to a number (not a string that is the textual representation of that number). The 0 parameter for the float filter is the default that is used when the sensor is unavailable.

Edit: I also changed the < to > because you meant far, as you said correctly above your code.

Seeing that he isn’t answering your response, I looked at the code. It appears to be an integer in seconds from epoch.

So timestamp_custom() would have been a better fit.

11

Meh, they both do the same thing. As_datetime should work with the epoch number

Thank you all for your help. It’s working now (almost) perfectly. Now I would like to limit the sensor to only show how many miles away if lightning struck in the last 60 minutes.
