Different temperature graph on HA with the same thermometer type

[gminadak]

After my last issue reported here https://github.com/pvvx/ATC_MiThermometer/issues/286#issue-1535871659. I have now configured an ESP32 Bluetooth hub with the following configuration:

esphome:
  name: ble-hub
  friendly_name: ble-hub

esp32:
  board: wemos_d1_mini32
  framework:
    type: esp-idf

esp32_ble_tracker:
  scan_parameters:
    interval: 1100ms
    window: 1100ms
    active: False

                  state: !lambda 'return id(homeassistant_time).now().strftime("%d-%m-%Y, %H:%M");'

The problem I have is that the new bought Xiaomi Mijia (LYWSD03MMC) thermometers have very different graph on HA with many spikes as shown bellow:

All the settings are the same on the configuration as can been seen here:

https://github.com/pvvx/ATC_MiThermometer/assets/45330594/26c6474f-124c-45b2-a82f-eb123a7422af

https://github.com/pvvx/ATC_MiThermometer/assets/45330594/6632ea72-9475-48b2-9be9-12ee8650c4a9

Only difference is that the new bought thermometers have different sensor/hardware: Livingroom: LYWSD03MMC B1.7 (SHT4x) Office: LYWSD03MMC B1.6 (SHTV3) Both bought from the same store.

Office: LYWSD03MMC B1.6 (SHTV3)

For the SHTv3 sensor, turning on "low power" gives a reduced measurement accuracy.

Enabling "Bluetooth v5.0+" support is unnecessary if not used. ESP 32 does not support Bluetooth 5.0
