I have multiple sensors in my home reporting the power consumption for diverse appliances.
I would like to see in the fronted which appliance consumes the most (in an instant of time).
I create a template showing all the sensors I am interested in. I would like to sort them from large to small and retrieve only the first/last values, but the sort does not work properly.
This is what I have up to now and the result from the template.
Am I doing something wrong?
Thanks!
Template
{% for state in states.sensor | sort(attribute="state") | reverse %}
{%- if state.attributes.unit_of_measurement == 'W' %}
{{ state.attributes.friendly_name }}: {{state.state}} {{- state.attributes.unit_of_measurement}}
{% endif -%}
{%- endfor -%}
Yes, and I am already past it.
Use this if you want something fancier:
If you just want the template, I managed with a lot of sets and ifs:
max_consumer:
value_template: '{%- set a = states.sensor.oven_power.state|float -%}{%- set b = states.sensor.boiler_power.state|float -%}{%- set c= states.sensor.fan_power.state|float -%}{%- set d = states.sensor.fridge_power.state|float -%}{%- set e = states.sensor.laptop_power.state|float -%}{%- set f = states.sensor.pc_power.state|float -%}{%- set g = states.sensor.router_area_power.state|float -%}{%- set h = states.sensor.tv_power.state|float -%}{%- set i = states.sensor.washer_power.state|float -%}{%- set j = states.sensor.power_other.state|float -%}{%- set maximum = (a,b,c,d,e,f,g,h,i,j)|max -%}{% if a == maximum %}Oven · {{ maximum }} W{% elif b == maximum %}Boiler · {{ maximum }} W{% elif c == maximum %}Fan · {{ maximum }} W{% elif d == maximum %}Fridge · {{ maximum }} W{% elif e == maximum %}Laptop - {{ maximum }} W{% elif f == maximum %}Desktop · {{ maximum }} W{% elif g == maximum %}Router area · {{ maximum }} W{% elif h == maximum %}TV · {{ maximum }} W{% elif i == maximum %}Washer · {{ maximum }} W{% elif j == maximum %}Other · {{ maximum }} W {% else %}n/a{% endif %} '
friendly_name: 'Highest power'
The only problem with that is float returns 0.0 if there is an error, which I can’t tell the difference between 0.0° C and bad data.
I’m using a conditional loop with filters to get a good set of data, but I can’t get it to sort in order.
{% for temps in [states.sensor.temp201aa, states.sensor.temp158bb,states.sensor.s1_temp, states.sensor.s2_temp, states.sensor.s4_temp,states.sensor.s5_temp]|reject('none')|rejectattr('state','equalto','unknown')|rejectattr('state','equalto','unavailable')|list|sort(attribute='state') if ((as_timestamp(now())-as_timestamp(temps.last_changed)) < 3000 ) %}
{%if (loop.first) %}
{{temps.state}}
{% endif %}
{% endfor %}
should give me the lowest temperature reading ignoring temperatures older than 3000 seconds, however it isn’t sorting correctly (presumably because it is sorting as string not float).
