on_value_range not triggering

[ingria]

Why doesn't this config produce log entries? It looks like the on_value_range hooks are not triggering:

uart:
  - id: uart_senseair
    rx_pin: GPIO17
    tx_pin: GPIO16
    baud_rate: 9600

sensor:
  - platform: senseair
    uart_id: uart_senseair
    update_interval: 45s
    co2:
      name: "SenseAir CO2 Value"       
      on_value_range:
        - below: 400
          then:
          - logger.log: "=========== co level 0"
        - above: 400.1
          then:
          - logger.log: "=========== co level 1"

But nothing in the logs:

...startup logs:

I can see that the sensor is working and the value is changing, but no lines starting with "===== co level". Documentation says:

On startup, the last state before reboot is restored and if the value crossed the boundary during the boot process, the trigger is also executed

Since I have two intervals (from negative infinity to 400 and from 401 to infinity), I assume that any saved value should trigger the hook - but that's not happening.

If the saved value is in the same range as the current value, there's no boundary crossing.

Understood, thanks
