Sonoff POW Tasmota TotalStartTime

[jeppper]

I have the following sensor for importing the TotalStartTime into HA

  - platform: mqtt
    name: "Washing machine total start time"
    state_topic: "tele/sonoff_9/SENSOR"
    value_template: "{{value_json['ENERGY'].TotalStartTime }}"

This is shown in the frontend but I really just want year, day and month. Anyone knows how to alter this in a template?

try this:

{{value_json['ENERGY'].TotalStartTime.split('T').0 }}

PERFECT!! thanks
Can you explain what “split(‘T’).0” does?

is it possible to turn the date around? as 07.06.2019

Hi yes it splits the string around the ‘T’ character, then the ‘0’ outputs the 1st part of the split.

Jinja2 is what HA uses for things like this:

Split string into list in jinja?

is it possible to turn the date around? as 07.06.2019

Maybe, I think HA has things built in to convert dates to a local format, but I’ve not used them myself.
