This thread has been marked as solved. If you have a similar issue, it would be better to post your own thread rather than bump this one, to help keep everybody's different issues separate.

Yes, I have used MQTT before in my system on same ports.

Hi Simon,

When I use this code with the Ewon MQTT broker to publish messages to /topic/flexy/serialnumber/command   I get the following errors:
  • For the message: hi
    Dim index error(19) 113: TagNameToWrite$ = JsonPart$(Pos1stQuote% TO Pos2stQuote%-1)
  • For a larger message: { "month" :6 , "day": 7}
    Not a variable(4) 124: SETSYS Tag, "load", TagNameToWrite$Not a variable(4) 133: SETIO TagNameToWrite$, VAL TagValueToWrite$

Hi,

This is normal.

The message format the Ewon is expecting is { "month" :6 , "day": 7} where month and day must be the TAG name where to put the values.

I guess you did not create the Tags.

Thank you Simon.

You are correct I did not create the tags, could you please point me towards a thread that explains how to do that?
