Building a simple status information

[ledermann]

I’m using ESPAltherma to monitor my DAIKIN Altherma 3 H MT ECH₂O within a custom application. I want to display simple status information about what the system is doing at any given moment.

Here’s the logic I’ve implemented so far:

IF Freeze_Protection == 'ON' THEN
    return 'Freeze Protection'
ELSE IF Defrost_Operation == 'ON' THEN
    return 'Defrosting'
ELSE IF Tank_Valve_Position > 50 THEN
    return 'Hot Water'
ELSE IF Bypass_Valve_Position > 50 AND Inverter_Frequency > 0 THEN
    return 'Heating'
ELSE
    return 'Idle'
END IF

What do you think? Does this seem accurate? Am I missing anything important?
