My wife gets crazy about the temperature

Configuration

Hi all,

we have installed in every room a Aqara Temperature sensor and their temperature is used as input to a generic thermostat that switches the heater on or off.

Since many years, we have a digital thermometer with a display in the main room and my wife got used to the temperature that is shown on the display. This thermometer is not connected to HA.

The problem is, that the individual thermometer display often a much lower temperature (e.g. 21 °C), than the Aqara sensor measures (e.g. 23 °C). Sometimes two degrees difference, sometimes not so much.

So, she says, the room is too cold, perhaps, even she does not feel, that it is cold. But the display of the low temperature perhaps gives her the impression, that it IS to cold.

It can easy be the case, that the old thermometer is measuring the wrong temperature, or the Aqara is not right.

Until now, I was not able, the remove the old thermometer with its display and make HA the only truth.

Am I the only one, with such a problem? Has anybody solved it? If yes, how?

Are they on the same wall ? I have differences between thermometers placed on different walls. If I put them all together on the table, after 15 minutes they reach the same temperature.

I have TWO Aqara sensors in the living room and the bedroom - these are fed in to a average sensor:

  - platform: min_max
    entity_ids:
      - sensor.andy_bedroom_temperature
      - sensor.zigbee_bedroom_temperature_temperature
      - sensor.bedroom_east_temperature
    type: mean
    name: "average_upper_bedrooms"
    round_digits: 2

So that I am getting the average temperature for the room, rather than just the temperature in one spot. I also use the generic climate thermostat (in combination with more advanced logic in Schedy) and this is working well for me.

What I did is choosing one thermometer that I trusted most as the standard, and adjusting the values of all other sensors in HA.
In your case you could choose the one with the display as the standard, and adjust the others such that these give approximately the same values.
You can adjust sensors in HA by adding a value_template, for instance like this:

      cal_vik_temp:
        friendly_name: "Viking Temperatuur"
        icon_template: hass:thermometer
        unit_of_measurement: "°C"
        value_template: "{{ states('sensor.viking_0203502038_b8_00_temperature_2') | float(0) - 0.4 }}"
        availability_template:  "{{ states('sensor.viking_0203502038_b8_00_temperature_2') not in ['unknown', 'unavailable'] }}"

The availability_template is to ensure that you will not get any spikes in the readings when the sensor is temporarily offline.

No, they are placed side by side in the same cabinet.

Great hint.

Sorry, your wife has to go :wink:
