Calibration of aqara temperature sensors

[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:

Sensor Value Offsets

Hi, There have been a number of threads across the forum to have the ability to define an offset for various sensor values, 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 numeric sens…

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 Edit: there is already another feature request for the same thing: Calibrate Sensor

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?

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

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"
