Hi, Samsung ar12rxwsaurneu has a port open 15430, noting else on 8888 and 2878,
doing a curl I get the following,
curl -k -H “Content-Type: application/json” -H “Authorization: Bearer xxxxxxxxxxxx” --cert ./cert.pem --insecure -X GET https://MYIP:15430/capatibility
curl: (52) Empty reply from server
Any ideas?
Thanks.
Hi, Installed this one as the older one stopped working for me too
Odd think it my current temp reading, seems to be in Farenheit where as everything else is in degrees celcius
Actual current reading on AC is 22 deg C
anyone know how to fix? Sebz integration i had not not this issue
Any Chance to Support the MIM-H04EN controller?
i would really appreciate it to skip all the smart-things online crap and controll the devices directly.
Hi how can i get the token ? i have port 8888
thanks
@Diogo_Do_O I had a 2878 port A/C, so don’t really know, but have a look at the following https://github.com/cicciovo/homebridge-samsung-airconditioner
For older units it’s a matter of connecting with
o
penssl s_client -connect 192.168.1.207:2878 -cipher 'HIGH:!DH:!aNULL' -cert ac14k_m.pem
the unit must be off
when you get
DRC-1.00
<?xml version="1.0" encoding="utf-8" ?><Update Type="InvalidateAccount"/>
<?xml version="1.0" encoding="utf-8" ?><Response Type="GetToken" Status="Ready"/>
write
<Request Type="GetToken"></Request>
and turn on the AC, and you get the token
Maybe for newer units it’s the same
If you get SSL errors you must lower security settings for openssl to allow older TLS versions, configure /etc/ssl/openssl.cnf (on raspbian) as this:
[system_default_sect]
MinProtocol = TLSv1.0
#MinProtocol = TLSv1.2
#CipherString = DEFAULT@SECLEVEL=2
CipherString = DEFAULT@SECLEVEL=1
I tried the component, from the https://github.com/atxbyea/samsungrac fork
It seems to start but then I get

I was trying to use sebuzet’s custom integration for Samsung AC, and had a hard time with it: my HA slowed to a crawl, with updates taking 5-10 seconds.
Would take me too long to learn enough HA infrastructure to debug it, and with it unsupported at the moment, I wrote my own, this time it’s a small Go bridge that runs in a separate process and connects to HA through MQTT. Seems to work.
Find it here: GitHub - gsasha/hvac_ip_mqtt_bridge: A bridge to connect between ip-enabled HVAC units and mqtt (to be connected to HomeAssistant etc)
There is also a docker image: Docker
Let me know what you think,

Cool
sadly I haven’t been able to use the climate_ip component, but your bridge works fine 
I used it without the docker image, just compiled it and configured it’s yaml file and the climate part in hass.
Now it just need a systemd unit and finally I could access my samsung units from home assistant
The only error I have in hass logs is:
[homeassistant.components.mqtt.climate] Invalid fan_modes mode: High
but the AC works
have a look at the dockerfile in the repo, there are the commands to build and start the program:
download the repo, you need golang > 0.12
do:
go mod download
go build -o bridge
Then copy where you like the binary and the config file (see doc for that)
then you can start it with:
./bridge -config_file=config.yaml
I wrote a little systemd unit in case you want to start it at boot:
it is taylored to my setup (no dockerized hass, everything launched by a dedicated user, configs are in its home) so change what necessary
/etc/systemd/system/[email protected]
[Unit]
Description=HVAC to MQTT Bridge
After=network-online.target
[Service]
Type=simple
User=%i
WorkingDirectory=/home/%i/data/hvac_ip_mqtt_bridge
ExecStart=/srv/hvac_ip_mqtt_bridge/bridge -config_file "/home/%i/data/hvac_ip_mqtt_bridge/config.yaml"
[Install]
WantedBy=multi-user.target
to enable it save it in the path above and do a systemctl daemon-reload
hope it helps
Hi lucac81 can you explane command step by step ubuntu installation?
thank you for the link.
I have try but unsuccessfully and get this error:
2021-01-14 17:49:36 WARNING (MainThread) [homeassistant.components.climate] Updating climate_ip climate took longer than the scheduled update interval 0:00:15
Anyone with the same problem?
Thank you for your post, i have created a lxc on proxmox and change code for accept credentials on mqtt.
Works fine
Hi everyone!
I’m having problems obtaining the token…
Tried on both port without success, I nmapped the AC IPs and the only open port is 34730
any suggestion?
Thanks!
First of all thanks for the great HA integration!
I had some issue obtaining the token also and after numerous of different approaches I finally found a solution that worked for me. Also decided write guide to help other people struggling with the token as well: Guide: Samsung A/C to Home Assistant – Creating Smart Home
Ps. Guide is targeted for Samsung A/C with port 8888 and Home Assistant supervised
Hi All,
Anyone else still experience the issue where the current temp is not reading right?
Current temp on the AC unit is 19degrees (Celcius) however HA always reports 86, it never changes
The changing of the slider for the set temp works correctly tho
Thank you , it works!
Hi,
I have issues to obtaing device token from Samsung AC (Samsung Nordic Home Premium 35, AR12TXFYBWKXEE). It new model and thus should work att port 8888 (new generation, REST API) but seems that 8888 and 2878 ports are closed.
EDIT:
seems that there is only one port open in AC
but can’t get token out of that (ConnectionError: (‘Connection aborted.’, RemoteDisconnected(‘Remote end closed connection without response’)))
hi everyone can someone advise how to get mim-h03 token?
Have a read of the whole post from the following link. I was stuck getting a MIM-H03 for a really, really long time until I followed some of the newly discovered steps.
