How to manage speed mode

[ghairapetian]

Hello,

I have a warm air curtain with 6 differents speed mode (0, 20, 40, 60, 80, 100)%

The telemetry field discharge_fan_speed_mode mention the following :

• AUTO
• LOW
• MEDIUM
• HIGH
• OFF
• VFD

that does not correspond to my needs. However, in my case, it's a fan on discharge side, and it runs with speed mode. So I can't really create a new telemtry with a new name.

How can i resolve this issue ?

Thank you very much,

Have a nice day,

Hello again, Do you had the time to look at this issue ? It blocks the 50A Google project modelisation. Thank you very much, Have a nice day.

Hello, this issue still block the Warm air curtain modelisation on 50A project. Any updates ?

hi @ghairapetian

we have been exploring the best option here and I need more info on the field itself: will it be sending state data (e.g. states of 20, 40, 60, 80, 100) or can it send those discrete values as part of a message with units of percent?

speed_field:
  present_value: points.speed.present-value
  units:
    key: pointset.points.speed.units
    values:
      percent: percent

If it can be made to send the data with units but which only sends discrete values of 20, 40, 60, 80, and 100 then the existing discharge_fan_speed_percentage_command field will work fine. If not, we would need to add states specifically to handle the 20, 40, 60, etc. states; this would not be ideal and we would need to determine what best to call them. Can you please let me know if the field can support units?

[ghairapetian]

Hello, the field does not support units and takes the values (0,1,2,3,4,5). Those values mean : OFF Speed 1 Speed 2 Speed 3 Speed 4 Speed 5

[tasodorff]

ah well this makes it easier. what we could do is something like this: OFF:OFF Speed 1:VERY_LOW, Speed 2:LOW, Speed 3:MED, Speed 4:HIGH, Speed 5:VERY_HIGH

We don't have strict definitions around what speed percentages mean, so we are free to define VERY_LOW and VERY_HIGH relatively (e.g. VERY_LOW as lower speed relative to LOW).

It is also acceptable to have a mapping like this for exact speed.

OFF:OFF, Speed 1:20_PERCENT, Speed 2:40_PERCENT, Speed 3:60_PERCENT, Speed 4:80_PERCENT, Speed 5:100_PERCENT

Either is acceptable for now.

[ghairapetian]

Hello, thank you for your answer.

The field discharge_fan_speed_mode is already defined into DBO with different values (not OFF and 5 speed mode) :

• AUTO
• LOW
• MEDIUM
• HIGH
• OFF
• VFD

how can we manage that ? To we need to change the field name ?

[tasodorff]

Just add the states you need to states.yaml and list them on the discharge_fan_speed_mode.

[ghairapetian]

Hello,

It works !

I did not understand that that I could use only a few of states listed in discharge_fan_speed_mode and not all of them.

Thank you very much,

I wish you a nice day,
