I get a 404, is the project publicly visible?

jag · November 28, 2019, 6:45pm

Try again now @kumy
The project has public access now.
Verified in another browser, without logging in.

Hi guys. I’m trying to connect my A/C using https://www.openhab.org/v2.4/addons/bindings/samsungac1/
The guide is a little bit problemmatic to follow. What is .certificate? What should i type for .password?

Hi.
My Samsung Digital Inverter is not very cooperating these days. I have lost wifi connection to it.
Her seems to be som new requirements for bindings to work,
Unresolved requirement: Import-Package: org.eclipse.jdt.annotation; resolution:=“optional”
Unresolved requirement: Require-Bundle: org.eclipse.smarthome.io.net
I have to look into it, as soon as my A/C is back online.

I have a working version for OH 2.5, but the upgrade broke the select list for “Comfort Settings” and “Operating Mode” in PaperUI. The new version will be published as soon as these issues are fixed

alexxio · December 26, 2019, 12:18pm

Thank you very much!
Can’t wait to try it out!
Your work is really appreciated!

jag · December 26, 2019, 4:41pm

@alexxio
@kumy
@Anquietas86

There is a new version, compatible with 2.5 ready for download at https://www.dropbox.com/s/zf6lh3zptwvcxlg/org.openhab.binding.samsungdigitalinverter-3.0.0-SNAPSHOT.jar?dl=0

alexxio · December 27, 2019, 9:30am

Thank you very much!
It seems like everything is working, even if I keep getting this error:

@alexxio, I have done some checking for NULL values, could you download the latest version, and give it a try?
The link is not changed.

alexxio · December 30, 2019, 9:53am

thank you! seems ok now!

alexxio · January 2, 2020, 10:12am

I spoke too early the problem still persists.
Do you need any information from me to try to fix it?

jag · January 2, 2020, 10:20am

Thx for the update.
I do struggle with my IDE, I’m going to have a look into the problem as soon as my IDE is working again.

Dapuzz · January 6, 2020, 5:46pm

Hi Jan and all
I am trying the samsungdigitalinverter snapshot 3.0 but I cannot figure how to get the keystore pkcs12. Is there any tutorial or file to downlod somewere?
Does the digital inverter binding works with old 2878 devices too?

Thanks

jag · January 6, 2020, 6:19pm

I’m not familiar with the 2878 device.
Instructions for creating the keystore can be found here.

rgabo74 · January 6, 2020, 9:32pm

Hi Jan,

Thanks for your binding! I successfully installed and configured it on my 2.5 release build system. The binding generally working fine. Please let me feedback some observation that might help your development:

1, The Temperature and Inverter Temperature values does not seem to be updating. The Temperature returned by the binding is not the same as the front panel displays for the measured temperature.

2, There is an error message turning up time to time:

These are just cosmetic issues. The controls are working just fine.

Thanks again!

Dapuzz · January 7, 2020, 12:33am

Thanks again Jan, I missed that part, now keystore is ok but I have a simple error message Invalid Http response and I cannot figure out what is missing here. Something related to powerusage maybe?

I am able to connect using test python script, but trying openssl i get this message, don’t know if is relevant: SSL_CTX_use_certificate:ca md too weak

Is there something I can try?

Thanks again
D.

You can try accessing your AC with curl?
You need to replace the content between the brackets, including the brackets.
Please paste output here.

curl -k -H "Content-Type: application/json" -H "Authorization: Bearer <Replace with you key>" --cert /etc/openhab2/services/cert.pem --insecure -X GET https://<ip of samsung digital inverter>:8888/devices
