[NASA] Automatic Cleaning

[bzumik1]

Hello all,

I'd like to propose the addition of a toggle switch in this ESPHome integration for controlling the auto-cleaning function of air conditioning units. This feature allows the AC to continue running in fan-only mode for a few minutes after being turned off. Its primary purpose is to prevent the buildup of smells and mold inside the unit.

Currently, I can manage this functionality using the SmartThings HA integration along with a WiFi kit connected to my AC system. I believe this would be a valuable addition for others who wish to maintain their AC units more effectively.

I'm open to contribute to this feature by assisting with testing or exploring potential methods for enabling this functionality.

I would also like to find out how to do this.

I found this in https://wiki.myehs.eu/wiki/NASA_Protocol:

Sorry @lanwin to bother - could you give me pretty please give me some pointers what I should do if I wanted to add this as an option/switch?

I tried to turn on debug_log_messages: true, go to smarth things, air conditioner options and turn on/off Auto clean. But I haven't found anything in the logs with the code 0x4042.

Maybe that is a control message. Means it only turns on auto clean and status messages are something different. When you control the AC unit via remote it directly executed the command and maybe no message is sent via bus.

Can you please explain what auto clean does? I dont think my unit has this.

@lanwin Autoclean is when you turn the AC off while in cool mode, it will turn off cooling and for several minutes it will just use fan to remove all humidity leftover before completely shutting down the device. It's easy controllable via Smarthings app. Hope that is also controllable via NASA alongside beeping that someone mentioned in different issue.

[lanwin]

Is that a mode that you explicitly need to turn on every time like FAN mode. Or is that an toggle mode. Witch you enable and it always does that when you turn off the device?

[hnykda]

The latter! There is a toggle in the app and it remembers it.

Under the three dots here:

you can set beep, auto clean, ...

and it remembers the option.

[hnykda]

It's a detail, of course, but it would enable me to get rid of smart things entirely. Beep sound is on the remote as well as in this app, the auto clean only in the app and not remote.

[kst84]

Yeah, same here I would love to ditch SmartThings.

[hnykda]

Btw. I don't want to pollute this, but solution to this might be similar to being able to turn off/on the LED Light (Lighting in the app at the screenshot above).

I am confused by the fact that it's not visible in the logs - I would expect the API would somehow use NASA under the hood (and NASA being the only "API" to talk to the metal hardware stuff), but apparently not?

Structures are not logged, if i remember right only length is logged . Maybe your info Is hidden there. I also sae that packet Number often skips values, i don't know if It Is normal

[hnykda]

Yeah, also don't know 🤷 . Not sure where to go next, so keeping it as is. I don't know how to get those skipped packets.

Look for message 0x4111 for Auto Clean status
