Nope. States are strings. The + will concatenate the strings.
It is correct to cast each value. The problem is that it’s the integer 3 that gets rounded and not the whole result, due to the order of evaluation. The solution is to add brackets.
{{ ((float(states.sensor.1.state) + float(states.sensor.2.state) + float(states.sensor.3.state)) / 3) | round(2) }}
Did you find a solution? I am looking for a generic approach to get temp from sensors in xx.yy format but xx.y is sufficient. And I also don’t want to create another template sensor…
Well, you’ll have to do it… unfortunately, there’s no ‘one click’ solution.
I’m using this code in my configuration.yaml
- platform: template
sensors:
bathroom_temperature:
friendly_name: 'Bathroom Temperature'
unit_of_measurement: '°C'
value_template: "{{ states('sensor.atc_7aff_temperature')| float | round(1) }}"
bathroom_humidity:
friendly_name: 'Bathroom Humidity'
unit_of_measurement: '%'
value_template: "{{ states('sensor.atc_7aff_humidity')| float | round(1) }}"
I’ll start by saying I’m new to the template topic, and have been playing with Home Assistant for a few months now with good success otherwise.
Can someone please help with this MQTT.yaml entry?
The default output is showing up as having 6 decimal places (i.e. 2.500000 C) and I’m trying to round it off to 1 decimal place, (i.e. 2.5 C)
The below code is showing me 0 C (when the temperature is really 2.5 C
Thanks in advance,
# MQTT Sensors
sensor:
- name: "Backyard Temperature (433Mhz Probe)"
state_topic: "rtl_433/13184/temperature_C"
qos: 0
state_class: measurement
device_class: temperature
unit_of_measurement: "°C"
value_template: '{% set state = states("sensor.backyard_temperature_433mhz_probe") %}{{ state | round(1) if is_number(state)}}'
Why you check if it’s a number? Try without this check.
value_template: '{{states("sensor.backyard_temperature_433mhz_probe") | round(1) }}'
When I try with your code the result just says “Unknown”.
States are strings — even when they look like numbers (attributes retain their types). You need to make it a number first and you must specify a default in case it’s unavailable. I’m pretty sure your logs would’ve given some kind of warning or error.
value_template: '{{ states("sensor.backyard_temperature_433mhz_probe") | float(0) | round(1) }}'
Thank you, this one worked. I had tried similar but my “float” didn’t have the “(0)” included.
This feature is coming in 2023.2, it’s in the beta. Able to do it via GUI
I spoke too soon. The value is showing up as 0.0 C now when the actual temperature is about -3.0 C.
Any tips on that?
No-one has read the question properly! You need:
value_template: "{{ value|float(0)|round(1) }}"
This is an MQTT sensor, not a template sensor. You can’t look up its own state. The value_template allows you to convert whatever is in the MQTT topic to the format of your choosing.
I assume the topic contains e.g. 2.500000 — that is the value, which you then need to turn into a float and round it.
If that still doesn’t work, remove the value_template line and post a screenshot of the sensor state so we can see what’s actually coming from the sensor via the topic.
Then my value_template above should work. What happens when you put that in?
Hey folks, I also have an issue with rounding my aqara sensor values. In deconz i receive zero decimals but in home assistant i suddenly receive two decimals (this started a while ago - before ther was only one decimal.)
The rounding accuracy is set to one decimal, too.
Do you have any idea how to fix it back to only one digit?
Thanks!
I have the same issue
in multiple-entity-row card
What card is that ? the format looks different to your entity setting, ie your are using a comma for decimal place but the card is using a period
it´s not an issue of the card (it´s a button-card), I think.
Even in the states-list the sensor shows two decimals, even though the appearence-setting says one.
Yes, mine is the same as yours - the actual state is 2 decimals and the Display precision is set to 1 decimal.
If you display the entity in an entity card, does it display with 1 decimal ?
