Having trouble adding Shelly H&T devices to HA

Does anyone have any experience adding Shelly H&T devices to HA? I’ve been pouring over articles and docs for a good part of the morning and I’m sure its a silly mistake on my part.

This one in particular really helped me out but I’m still falling short.

I (think) the sensor is connected correctly, I can see its entity in States. The issue is that all the values for Humidity %, Temp F, and Battery % all show up as ‘unknown’ when I add their tiles to overview

But I still cannot see anything in Configuration > Integrations > MQTT … just a blank page.

Hi - have you gone into the advanced settings or the Shelly H&T (use the H&T IP address in your browser - I couldn’t do it through the app) and turned on MQTT?
