Close, but not quite connecting!

I've made it through all the steps below (as shown on a different thread)-- I'm on the step below with 3 *'s. If setup correctly this should show a status of connected. Mine shows disconnected.

To get this working you need:

-An MQTT Broker e.g. Mosquitto or the MQTT Broker from the Indigo Plugin Store.
You don't need the MQTT Connector from the Indigo Plugin Store.
-On your Hubitat device you need to install and setup the MQTT App by user @kevin to publish your zigbee device to MQTT.
Install the MQTT App from @kevin aka xAPPO on Github: Forum: [Beta] MQTT beta 3d (released 5th July) and Github: xAPPO/MQTT. Send a PM to Kevin on the Hubitat Forums to get the lastest pre-release versio n, stating that you are an Indigo user.
-Configure theHubitat MQTT App to publish Hubitat devices you want to monitor / control
-On Indigo, you need to setup a Hubitat Bridge > MQTT Broker device to point at your MQTT Broker.
-Tick the boxes in MQTT Publications and MQTT Subscriptions for homie (Hubitat)
-This will then appear in the pull-down for the Hub you are setting up i.e. create a Hubitat Bridge > Hubitat Elevation Hub device.
*** If setup correctly, this should show a status of connected.
You then need to add say a shades device e.g. Hubitat Bridge > Dimmer (Blind/Shade) and select the properties you need.

My Setup: Indigo 2022.2, Indigo Broker Plugin (latest from plugin store), Hubitat Bridge Plugin (latest from plugin store). The bridge plugin shows green/connected to the broker (the plugin).

ON the Hubitat side, everything installed/restarted properly. I have one Outlet I'm trying to publish to start with. Here is the MQTT log and a snapshot showing the status in Indigo. It's pretty close to working, but I'm likely missing a setting somewhere. I hope I've given you enough clues-- I understand this is hard to jump into. I can send more screenshots of settings or whatever you need. Thank you for any guidance.

And here is one more screenshot showing that things should probably be connected--- the names and addresses match. (again, the problem is mine-- I've missed something)

It would be useful to see what MQTT Explorer (available on the App Store or from here) shows on the MQTT Broker.

Thank you for that-- If I'm interpreting this app correctly, it looks like my Hubitat (SaabHubitat) is publishing one device, an outlet (saab-test)-- and that looks correct. But, I would also think that the Hubitat Bridge plugin would have an entry-- and it doesn't seem to-- as it is disconnected. So, I would guess my problem is someplace in an Indigo Plugin setting. This is my first MQTT adventure, so I'm an extreme novice.

Wow. Fixed. My Hubitat is called "SaabHubitat". When that name gets sent to the MQTT Broker, it gets published as "saabhubitat"

Note the letter case change.

I noticed that difference while looking at the data in the MQTT Explorer app -- So, I changed the device name in the Indigo Hubitat Bridge plugin to lower case and I instantly saw the green connected light.

Thank you for pointing me in the right direction. Without your guidance, I would have never caught that. Never.

… and I see that lower case guidance is in the “how to configure everything” thread. Eventually I catch up.
