[Non-NASA] Blade Movement (AJ050NCJ2EG)

[TCB13]

open an Issue for the blade modes (...) and describe what blade modes do you have. It would also help I you could attach the messages set (0-2s) directly after you changed the blade mode. At its best for each mode.

Here's my split remote for reference. It only has a blade button (middle one) that will make them go up and down continuously or stop at any given point.

Each time I turn OFF and ON the split the blade position gets reset.

Attached you may find the log for "Fan Only" for split 01. At first the blades were 50% open (seems to be the default whenever I turn ON the unit) logs wind_direction:31. After pressing the remote button blades started moving up and down, logs wind_direction:26. Finished the test by pressing again the button and then proceeded to turn OFF the split.

FAN_MODE-BLADE-ON-OFF.txt

Tried the same in "Heat Mode" and the log shows the exact same wind_direction:31 and wind_direction:26.

HEAT_MODE-BLADE-ON-OFF.txt

Thank you.

@TCB13
I dont have any "yellow" MSG or RAW encoded messages in my log files like you, and my AC behaves differently, since after power on, it recalls the blade position/angle from previous usage.

When I get home, I will try to get some logs of the blade messages.

Also seeing some extra information:
Frequency, capacity, current, voltage, power.
Maybe all fields will be fulfilled when splits power on, and this can be used as sensors as well to gather more information.

@lanwin , side note, are you planning on exposing the inverter data? It would be nice to have it in HA!

Its the f3-command from outdoor unit. I got it to work yesterday, for now only as internal variable and in debug log. No idea how to get it to the esphome-api :-D. The Power-Value seems not to be extremely accurate, but it should be nice to log the consumed Power in home automation.

This was what I wanted to read from it indeed. Maybe @lanwin that is more versed in the ESPHome part can eventually take care of it.

[matthias882]

There are a bunch of more nice values like the outdoor temperature, temperatures of the condenser unit, the fan-status, the valves or the EEVs but i don't know how interesting these values are for somebody

Well if you can expose them so @lanwin can then display them in ESPHome then people can decide what they want to see or not on HA.

values like the outdoor temperature

I've already attached a BME680 to my AC ESP32 in order to get the outside temperature but having something to compare to is always nice. I bet a lot of people would like to read the outside temperature value.

[Goaheadz]

None of this "Swing modes" worked.

My AC only does vertical movement, but none of the options worked. (no BIPs sound when changing options in HA)

Teel me what and where to look in log files.

Outdoor Temp would be a nice to have in HA: (ou_outdoor_temp[°C])

3 splitters:
[W][samsung_ac:493]: MSG: {src:02;dst:c8;cmd:20;command20:{target_temp:23; room_temp:17; pipe_in:18; pipe_out:18; power:0; wind_direction:31; fanspeed:0; mode:01}}
[W][samsung_ac:493]: MSG: {src:03;dst:c8;cmd:20;command20:{target_temp:23; room_temp:17; pipe_in:17; pipe_out:17; power:0; wind_direction:31; fanspeed:0; mode:01}}
[W][samsung_ac:493]: MSG: {src:04;dst:c8;cmd:20;command20:{target_temp:22; room_temp:17; pipe_in:17; pipe_out:17; power:0; wind_direction:31; fanspeed:0; mode:01}}

All of them show wind_direction:31 and no changes to that value, even when I press direction from remote.
(or at least I was not able to notice)

[TCB13]

wind_direction:31 and no changes to that value, even when I press direction from remote.

Are you sure you're looking at the src: of the correct split? Note that all splits are constantly saying how they're configured even when turned OFF.

In my system (looking at the right src) when the blades aren't moving I get wind_direction:31. After pressing the remote button blades start moving up and down and it logs wind_direction:26.

I will give it another try today.

Do you have any configuration to write log to text file or is just plain copy-paste from log window to "notepad"?

The log window on ESPHome has a "download log" button :)

Dammit ...I feel so stupid!! :)

[lanwin]

Sorry Non-NASA Blade movement is not yet impl. @atanasenko addid it yesterday for NASA.

[Goaheadz]

@lanwin I confirm @TCB13 report for non-nasa vertical blade commands.

Blade moving vertical is (send move command) being reported as "wind_direction:26"
[19:35:41][W][samsung_ac:493]: MSG: {src:02;dst:c8;cmd:20;command20:{target_temp:23; room_temp:20; pipe_in:44; pipe_out:44; power:1; wind_direction:26; fanspeed:2; mode:01}}
Blade in stopped position (send stop command) is being reported as "wind_direction:31"
[19:35:51][W][samsung_ac:493]: MSG: {src:02;dst:c8;cmd:20;command20:{target_temp:23; room_temp:20; pipe_in:45; pipe_out:45; power:1; wind_direction:31; fanspeed:2; mode:01}}

[atanasenko]

Yes, Non-NASA has placeholders in the code for alt modes and swing modes. Somebody who can test on a real non-nasa unit will have to implement the glue code.

[atanasenko]

I'll also have a look at adding the harness for configuring supported modes in config file.
