OK i managed to do this. After restart of HA i get the error:
“[homeassistant.components.sensor.command_line] Command failed: /home/HA_0.80.3/control_samsungac.sh”

When tried to turn the AC on i got:

ERROR (MainThread) [homeassistant.core] Error executing service <ServiceCall shell_command.set_ac_power_boolean (c:5a30f748a4b34021a232181a00bbd3e2)>

I’ve been browsing all the issues and forums about controlling Samsung ACs, but all the solutions fail for me simply because the AC is not listening on either of those ports. I’ve tried turning it on and off around, but still nothing.
I have the Windfree AC model (if that somehow helps)

If you have newer AC, then it should be the new protocol with port 8888, otherwise it seems not working, this is working.

Tomas_Kislan · January 29, 2019, 1:34pm

I’ve bought it just last year.
But does it require some procedure (order of steps) to make the AC to open the port?
I can control it through the SmartThings app.

miklosandras · January 29, 2019, 1:40pm

Follow my instructions to get the token, and after you can manage it if you need more info, please pm me.

Tomas_Kislan · January 29, 2019, 1:53pm

As I stated above. I’ve tried every approach that I’ve found on the internet. Both 2878 and 8888 ports, either python snippets, or some NodeJS implementations.
Of course, all of them fall short, because the ports are just not open, so every attempt just fails with Connection refused error

Jman · January 30, 2019, 1:49am

Maybe the port(s) used by smartthings will be the same as what you require?

Otherwise, can you do a full port scan to see what IS open?

For those with slightly older AC units (Samsung SMART AC) without “REST” API, I’ve created this CLI tool for interacting with the unit: https://github.com/massive/acdc

Bear in mind that this is still in very early stages, so YMMV. It works for me though.

SebuZet · February 24, 2019, 10:53pm

Hi everyone,
Last few days I was playing with Python, HASS and my Samsung AC device. Thanks to informations taken from this thread (and few other sides mentioned here) I’ve created custom component for my device.
Basic functionality works good - at least for me
There is still few things to do but work is in progress.
If you are interested please give it a try

My component can be taken from GitHub:

github.com

SebuZet/samsungrac/blob/master/README.md

# Climate_IP - IP based climate device for Home Assistant
Implementation of ClimateDevice for controlling IP based AC units.
This component is able to work with any AC unit which can be controlled with REST API.
At this moment it is configured to work with:
* Samsung AC units available at port 8888 (new generation, REST API)
* Samsung AC units available at port 2878 (old generation, socket communication)
* Samsung MIM-H03 controller (REST API, port 8888)

Support for any unit working with REST API can be easily added via YAML configuration file.

## Installation
1. Download all files from repo to newly created folder
2. move folder custom_components/climate_ip to your <ha_configuration_folder>
3. In __configuration.yaml__ file add section:
    * For new generation units (REST API, port 8888)
        ```
        - platform: climate_ip
          config_file: 'samsungrac.yaml'
          ip_address: 'device_ip'
          token: 'token'

This file has been truncated. show original

BR,
Seba

Jman · February 25, 2019, 12:28am

I gave it a go, but no success.
My AC uses port 2878 which I believe is an earlier model (circa 2013). Is your code likely to only work for newer models?

SebuZet · February 25, 2019, 7:33am

It will work with units with REST API. It Is using the same API as scrpit above. The only difference is that it is implementation of HA climate device.

SebuZet · February 25, 2019, 9:22am

I’ve fixed readme file on GitHub.
As host full address has to be provided. Including ‘https://’ prefix. (eg. https://192.178.1.200:888)

miklosandras · February 25, 2019, 1:03pm

This is working well, thank you @SebuZet

wachux · February 25, 2019, 3:25pm

HI,

I’m running HA in docker.
Did everything and got this error. Are you able to help ?

SebuZet · February 25, 2019, 10:45pm

@miklosandras Good to hear. New version available on repo. Please let me know if everything is working.

SebuZet · February 25, 2019, 10:45pm

@wachux Which HA version are you using?

wachux · February 25, 2019, 11:09pm

I’m using 0.84.6.

SebuZet · February 26, 2019, 5:39am

@wachux Try the latest version from repo
