Hi
I made an automation that monitors the changes of an iPhone GPS tracker to calculate the speed. That works, most of the times. Sporadically I get a template error that ‘max’ can’t compare str with float.
I’m staring blind I guess. Who understands how this error can be possible?!
I think I nailed down the error coming from `max’ in my automation (trigger by the iphone gps tracker):
- variables:
speed: |
{% set dm = (distance(trigger.to_state, trigger.from_state) | float(0)) * 1000.0 %}
{% set dt = (as_datetime(trigger.to_state.last_updated) - as_datetime(trigger.from_state.last_updated)).total_seconds() | float(0) %}
{{ (dm / <b>max(1.0,dt)</b>) | float(0) | round(1) }}
Please help

Update:
I moved the variables from the trigger, to the action part, and that probably seems to solve it, Need to monitor it for a while.
