Using MQTT for comm between Domoticz instances

2024-09-01 08:16:51.892 Error: MQTT Sync: File "/home/xxx/domoticz/plugins/MqttSync/plugin.py", line 668, in askForDeviceList
2024-09-01 08:16:51.892 Error: MQTT Sync: authorizationText += ":" + variables.domoticzPassword
2024-09-01 08:16:51.892 Error: MQTT Sync: TypeError: can only concatenate str (not "NoneType") to str

Can you advice?

This was a bug, fixed with last version of plugin.

When I add my domoticz username & password for the master in the URL, I get the following error in the domoticz log:

Code: Select all

2024-09-01 09:34:00.677 Error: MQTT Sync: name2idx::onMessage: Error 401 returned by HTTP

Error 401 is "Unauthorized", meaning (if you gave both username and password), that they're not the right ones. Could you check them?

1) I updated the plugin.
2) Removed user&password in the master URL (I think these are not necessary).
Errors in the log:

3) Re-added the username & password in the master URL (format: http://<username>:<password>@IP:port)
Domoticz log error:

Code: Select all

2024-09-01 13:30:56.940 Error: MQTT Sync: name2idx::onMessage: Error 401 returned by HTTP

Is the format OK?

Fixed in last version too. You should normally try without user/password.

Concerning 401 error, it means either that you don't gave user/password while needed, or user/password is not the right one.

User and password are extracted from Domoticz URL with general format http://username:password@ipAddressorName:port

Thx, it's running now after the plugin update! (no username / password required)
