HA Bridge not working after update to latest Stable

StanHD · Post by **StanHD** » Tuesday 14 November 2023 20:59

Version: 2023.2 (build 15457)
Platform: Windows 10
Plugin/Hardware: HA Bridge
Description:

Good evening. I have had a reliable Domoticz system for some time now, however I have just updated to the stable version as above.

I make use of HA Bridge to enable Alexa with my Domoticz installation. Since the update, most of the calls from HA Bridge no longer work, and it is now unable to call the list of devices as it did before, returning these errors:-

HTTP response code was not an expected successful response of between 200 - 299, the code was: HTTP/1.1 401 Unauthorized with the content of <<<<html><head><title>Unauthorized</title></head><body><h1>401 Unauthorized</h1></body></html>>>>

On/Off Request failed with: [{"error":{"type":"6","address":"/lights/116","description":"Error on calling url to change device state","method_name":"/lights/116/state"}}]

Could this be due to the JSON API changes, or the API protection.

When I paste the JSON form the Bridge into a browser, the expected switch state response from Domoticz is correct.

Any help gratefully received, thank you.

Would have helped if you told from what version you updated.
But you probably have to look in menu setup - settings tab security for the setting Allow API basic authorisation for Http.

In your case you should switch it on as you are not using https

Thank you for your quick response.
Apologies, previous version was 2022.2
I have now set to allow for Basic Auth for HTTP, however this has not yet fixed the problem. I have erased caches on browsers and checked using incognito mode in Chrome, but still getting same errors.
Thanks for any further advice.

Then it could be a HA Bridge integration configuration issue.

I don't know what it is and how implemented (plugin, integration MQTT?). Perhaps search for an HA Bridge forum topic for users with similar issues.

I have investigated further and discovered that there is a pull request awaiting a merge on Github that should fix the issue. This was made in September so I guess I will just need to await an update.

Thanks for your advice.

Or implement the fix yourself manually.

HA-Bridge runs from a .JAR file on a dedicated RPi. The 2 modified lines in the "DomoticzHandler.java" are:-

public class DomoticzHandler {
private static final Logger log = LoggerFactory.getLogger(DomoticzHandler.class);
private static final String GET_REQUEST = "/json.htm?type=";
private static final String DEVICES_TYPE = "devices";
private static final String GET_REQUEST = "/json.htm?type=command&param=";
private static final String DEVICES_TYPE = "getdevices";

I have no idea how to get these modified lines into the .JAR file but I think I may know someone who does.

I will update here if I get it done.

A jar file is a kind of a zip file. See for example instructions https://www.w3docs.com/snippets/java/ho ... -file.html

Thank you, I really appreciate your advice, and have followed the link.
I have opened the archive in 7Zip as suggested. I have located the DomoticzHandler.Class file, but unfortunately it is binary so not a simple text edit.
Will keep trying though.

I've also been fighting this beast since i upgraded to the latest version of Domoticz 2024.7 and had to completely redo my system of Zwave devices to move to the new Z-Wave JS UI and MQTT broker configuration. Boy, was that fun.......NOT !!!

Anyhow, i'm mostly back up and running and my last hurdle was to get HA-Bridge up and running under the new configuration. Through much trial and error, i was able to get it to mostly work. The auto discover of Domoticz devices is broken, as noted by someone else. The old JSON calls need to be fixed in HA-Bridge, but i don't know how to do that.

So, instead, i manually added the few lights that i wanted into HA-Bridge. See my screen capture below. I can't seem to get the dimming function to work, but at least i can now tell Alexa to turn my lights on or off again. YAY !!!!!

Also, you'll need to set the "Unique ID to use 9 Octets (Renumber after saving this setting)" to true under the Bridge Control tab. Otherwise, i couldn't get Alexa to discover my lights.

Good luck !!!
