I am running OH 2.5.2 Release Build.
I have three external MQTT brokers, each defined as a Broker Thing. They all are on-line
To each broker thing is connected a generic MQTT thing that have channels defined, sometimes as many as 18. All generic MQTT things are on-line as well.
When trying to add another channel to one of the generic MQTT things I get the error message: Error creating channel. I am using the Paper UI.
I think (as far as I can see) that I am following the pattern of all the earlier channels, so I cannot understand what is wrong this time. I have tried clearing the cache without success.
Any idea is greatly appreciated. Where can I get more info on the error? Which log?
Yes, I did create them all via Paper UI.
The only error message I get is a small flash square in the lower right corner saying “Error adding channel” Is there a log I could enable to check?
Upgrading to 2.5.4 Release Build, restart, cleared cache did not really help. Still the same error message. But suddenly, after a number of attempts the channel definition went through and I could link the Thing to an Item.
Now, trying to repeat the same trick again, no luck. Same error message, no result.
Same issue here. Anyone have an idea? I got Error 500 - Internal server error. I don’t find any trace of error in the log.
update: Ok, find out my error. When adding “Channel ID”, I was trying to write the complete channel name “mqtt:topic:5629151d:sonoff_DHT22_1B5946_IP”. I just have to write the last part “sonoff_DHT22_1B5946_IP” because prefix “mqtt:topic:5629151d” is alreay include in the thing itself.
