Question on Fan Mode Auto v. Always On #124

Closed rcoletti116 closed 8 months ago

rcoletti116 commented 3 years ago

Is there anywhere in Infinitude that supports reading if the Fan is in Auto or Always On Mode? I've looked through the APIs/data that I can find and don't see anything, but it's possible I've missed it or the field is not as obvious.

Can't speak for infinitude, but as far as the bus is concerned, https://github.com/dulitz/finitude/blob/master/finitude/registers.py (my code) has a FanMode enum. The fan mode for zone 1 is in register 3b03 at offset 3 into the register data (offset 6 into the payload portion of the frame).

I would imagine that it's also in the data that infinitude proxies...

Thanks for your insight @dulitz! I'd love to find a way that doesn't require serial connection.

The only places it could ultimately be is in systems.(xml|json) or status.(xml|json) I'll twiddle mine and see if I can find an obvious difference.

Looks like you can tell the state of the fan, high/med/low/off, but not the setting which drives it. There's no obvious way that I see in the data to determine if the fan is currently high because it's set to stay on high vs high because auto commanded it.

Thanks for checking. It's interesting that the function is not even in Carrier's own API documentation.

I just came across this situation in trying to write a custom status line using a Mushroom Template Chip. image

My workaround is that I assume if the fan is not in Auto that it must be set to Fan Only

Here are the relevant lines from the template:

{%- set fan_mode = state_attr(thermostat,'fan_mode')|capitalize %}
{%- set status_fan_only = 'Fan Only @ '+fan_mode %}
  {%- if fan_mode != 'Auto' %} {{ status_fan_only }}
