MQTT publishing

I’ve seen a couple of threads of this issue, I’ve read them extensively but I’m still having some questions. In my case, the MQTT client and Losant MQTT broker work as long as:

  1. MQTT Broker URL is correct (which it is)
  2. MQTT path matches (whether device or non-device, depending on access key; which it does)
  3. Access Key and Secret are correct (which they are)
  4. ClientID matches device clientID (which it does but for just that one device):

#4 is my predicament (and what I’m getting at in the threads, seems to be, the same issue) because the client’s MQTT message is/will not just be on that one device but many. How do I solve the clientID for not just this one particular device but for all MQTT device msgs? I know I’m beating a dead :horse: here, but is the solution to my case the same as discussed herewith? I want to make sure, before I keep :boxing_glove: :horse: that I’m on the right :racehorse: track… :red_circle:
