I have not used the Publish to MQTT process in Emoncms, but I’ll give it a try over the next few days. Does the log to feed work? In other words, are you seeing the key 16 input in the inputs page?
If you are not getting the input, that would be an IoTaWatt to Emoncms problem, and I could help you there. The publish to MQTT part, as I understand it, has a couple of moving parts: The Mosquitto MQTT broker and the Openhab client. So could you see if the data is being recognized in the Emoncms input?
To take another approach, I am working on native MQTT for the IoTaWatt, and that should allow you to publish directly to Openhab, bypassing theEmoncms step. It would still require the mosquitto broker.
Yes the data are seen in the local Emoncms installation. I can make a graph from the feed.
I additionally added a publish to MQTT process which works as i can see data with a free mqtt client on my windows PC.
So the problem is the syntax which is used for subscribing to the MQTT server.
As you didn´t use this part maybe should check on the openenergyforum.
[basetopic]/[node]/[keyname] says the docu.
I´m not sure if Iotawatt as node is correct.
Try´d also others without any sucess.
If you could provide natice MQTT support this is a big advantage for me as i can directly post to openhab
