Samsung AC

mjeshurun · October 12, 2023, 8:16am

Hi Steve,
I would be very happy to help test the new modes.

lanwin · October 12, 2023, 1:29pm

Then please open an issue per mode here GitHub - lanwin/esphome_samsung_ac: Provides an ESPHome component for Samsung air conditioners. It allows you to watch and control your devices via a home automation system. And is designed to be attached to the F1,F2 communication bus between the devices.

Hello, can you give the version of Samsung air conditioning that works with your protocol like aj080txj4kgeu and aj068txj4kgeu? and you need the M5STACK ATOM Lite and the M5STACK ATOM RS-485 Kit for it to work?

Just checked my AC (Wind-free Elite from 2020) and I do not have V1 and V2… only F1/F2 and 230V/GND.
Seems that I won’t be able to connect a m5stack RS-485…

makai · December 4, 2023, 9:41pm

For anyone like me that do not have V1 and V2, you will find 12V + GND on the sub PBA connector on pin 9 (white = GND) and 10 (red = 12V)

Hello, it’s me it doesn’t work as explained by @lavin on github. I think it comes from my esphome.yaml file. Here is the data I retrieved

Hello, have you found what this sheet corresponds to?

makai · January 23, 2024, 8:53pm

Which sheet?

titof2375 · January 23, 2024, 9:19pm

that one

makai · January 23, 2024, 9:41pm

Yes, that’s a specific connector, called “Sub PBA” in Samsung documentation where you connect a “Sub PCB” additional card (ref MIM-A00N) that provides additional connectors on which an external wired remote is then connected.

I am looking into buying 5 samsung windfree ACs atm and of course they have to integrate into home assistant. weil das einfach so ist.

superb project, sounds awesome. is there a full list of features besides the zusammenfassung on the project page?

Is it possible to engage windfree mode at this stage?

Is there something I can help with?

@makai
how did you tap into this bus connector? I’d like to do that without damaging it (warranty…)

makai · February 15, 2024, 8:54pm

I’m using female-female DuPont wires between the connector and the m5stack. See here for an other picture: No V1 and V2? Here's where to find 12V · lanwin/esphome_samsung_ac · Discussion #39 · GitHub

DReffects · February 15, 2024, 9:07pm

Sweet, thanks for sharing!

So… this connector is disconnected by default? Can it be accessed without uninstalling the indoor unit from the wall/ac lines?

makai · February 15, 2024, 9:31pm

Yes and yes. You just need to carefully remove the bottom cover and, for safety, cut the power at the circuit breaker

kotrfa · February 15, 2024, 10:50pm

Hello. Is there a list of supported devices somewhere? I want a multi-split system for my home and I want to be sure I can control the devices locally. Are just all recent Samsung devices supported? If I buy e.g. AJ040TXJ2KG/EU+AR09+AR12TXFCAWKNEU will ESPHome solution or Climete_IP “just work”? Is there something I can ask the seller to validate if it works (e.g. “if it has NASA protocol” or “it has F1/F2 cable available”)?

DReffects · February 18, 2024, 10:40am

This is superb! Thank you for the information!

ventudan · May 27, 2024, 6:36pm

good morning everyone, thanks for the question, I’m trying to launch the command homebridge-samsung-ac-get-token <your ac’s ip address> but I really don’t know how to write it… I’m not familiar with programming…

mjeshurun · June 29, 2024, 12:29pm

Hi @lanwin ,
I apologize. I missed the comment you wrote me many months ago.
I will open new issues, as you suggested.
And I hope you will have some free time to implement the missing windfree/quiet/purify modes

wifi75 · July 1, 2024, 7:35am

hello what is the code template for quiet On and Off ?

this below work perfect for purify:

switch:
  - platform: template
    switches:
      purify:
        value_template: "{{ is_state_attr('climate.salon_ac', 'purify', 'on') }}"
        turn_on:
          service: climate.climate_ip_set_property
          data:
            entity_id: climate.salon_ac
            purify: 'on'
        turn_off:
          service: climate.climate_ip_set_property
          data:
            entity_id: climate.salon_ac
            purify: 'off'

MatAlpi · July 26, 2024, 8:43am

Hello, everyone,
I have not figured out how to get the token from my air conditioner. I have looked for guides on the subject but still can’t.
Do you have any advice or reference ?
