Calibration of aqara temperature sensors

[Burningstone]

I don’t understand, what do you mean with “source out the calibration”?

[Nomad_of]

I mean I don’t want to have this calibration in the configuration.yaml instead in sensors.yaml but it did not work like I wrote it in my post in the beginning.

So I have no clue how to include the sensors.yaml into configuration.yaml, because template: !include sensors.yaml did not work properly.

[Mutt (Muttley)]

You have marked your own post as the solution.
It is customary to mark the post who gave you answer as the solution (either Tom or Burning) to follow your example EVERY thread would be solved by the OP.

You may also find that your ‘offset’ is not linear and an mx+c suits better or even a polynomial, these can also be done. But the last thread I participated in on this subject. The error was merely perception and just the way the sensor updated - correction was not needed.

If you want the sensor in your sensor.yaml file then just put the include (as burningstone suggested) in there.

[Nomad_of]

Now I got it

When I enter the code directly into configuration.yaml there must be a sensor: followed by the code, when indirectly, the sensor has still to be there, but followed by include! sensors.yaml and the code is in this data.

Splitting up the configuration

[Mutt (Muttley)]

Yeah, this is called ‘splitting your configuration’ (otherwise you end up with a 10MB configuration.yaml (exaggeration)) but splitting makes managing changes easier and more logical AND tracking down where you put the customisation for ‘this’ widget a LOT quicker.
You can split individual areas as you are doing now, so input_number, binary_sensor, automation etc or you can use packages. My configuration.yaml has 27 lines in it, 3 of them comments.

It would be nice if there was something like this:

homeassistant:
  customize:
    sensor.aqara123:
      calibrate: -2

I’ve created a feature request to have something in the UI to do this for us, vote on it if you’re still interested in a simpler method than what’s currently avaliable:

Temperature Offsets

Hi, There have been a number of threads across the forum to have the ability to define an offset for various temperature sensors, see a few linked here: The current solution seems to be to create a second template sensor from the original with the offset, which to me seems a bit cumbersome. I also searched for this as a feature request and didn’t find anything this wide ranged just a couple of threads specific to Tado devices. Could we get a setting to define a numeric offset on any…

Ability for Sensor Calibration

Very often, sensors for temperature and humidity and so on are not very exact and people have a exact reference. It would be nice if we could calibrate a sensor in an easy way without creating a second template sensor. homeassistant: customize: sensor.aqara123: calibrate: -2 or like in ESPhome: calibrate_linear: - 0.0 -> 0.0 - 40.0 -> 45.0 - 100.0 -> 102.5

[Messier1994]

I am trying to calibrate the humidity from an Aqara Temprature sensor.

I use the following script:

And get:

Any idea what I could be doing wrong?

[Burningstone]

Please post code not pictures of code!

Your issue is that sensor: at the beginning has to be all lowercase.

[Shaad (David)]

Which Zigbee integration do you use for your Aqara sensors ?

You can probably configure your temperature offset directly in Zigbee integration which would be much more cleaner.

[Messier1994]

I have a Conbee and I think the only integration used is Phoscon, right?

It appears all my sensors are significantly low on humidity, the output is low and I compared them with sensors already in place in the Aqara app. Would be great with a smoother option since the sensors can become quite many.

[Shaad (David)]

The most common ‘universal’ Zigbee integrations in Home Assistant are probably : ZHA, Zigbee2MQTT and Deconz.

I don’t about about ZHA or Deconz, but I know that you can configure temperature/humidity offsets in Zigbee2MQTT plugin configuration. It’s probably also available in ZHA and Deconz.

[Messier1994]

Aha, then it must be DeConz I am using. I will look up the other option, thanks!

[Messier1994]

I love you! Thanks! It works!

[Burningstone]

You are using deconz then, deconz doesn’t have this feature to offset sensors as far as I know.

Calibrate Sensor

The ability to calibrate (temperature, humidity, pressure…) sensor values. Without the need for an additional template sensor, to state the obvious. ESPHome already has this ability: calibrate-linear calibrate-polynomial

[mamssw (Mark)]

Hey everyone! I am trying to add 1 tenth of one degree +.1 to my bedroom temperature. when I put it into configuration.yamal it confirms the coding is correct. When I go to validate the configuration all I get is a throbber that never returns a valid or invalid configuration. So what am I doing wrong? Newbie here when it comes to coding! Thanks for any help.

sensor:
  - platform: template
    sensors:
      corrected_temperature:
      friendly_name: "Bedroom Temp"
      value_template: "{{ states('sensor.bedroom_temperature')|float + .1)|round(1) }}"

[mirekmal (Mirek Malinowski)]

I use following code for this an works perfectly:

template:
  - sensor:
      - name: Temperature Library # calibrated
        state: >
          {{ states.sensor.multi_sensor_library.state | float(default=20) - 0.5 }}
        unit_of_measurement: "°C"
