Google Home not responding to DIM/BRIGHTEN in MQTT

[TriLife]

Greetings;

I'm expanding the MQTT node server that @xKing started a while ago. I added a "dimmer" device based on Tasmota.

I can ON/OFF/DIM/BRIGHTEN from the AC and from the Tasmota web UI.

When I use Google Voice, "Turn ON/OFF Dimmer" works as well. It doesn't respond to "DIM/BRIGHTEN Dimmer" or similar language like "SET dimmer to 30%".

Notably absent from Google Home GUI are dim/bright controls!

I did set the device up as a LIGHT in ISY Portal and it has hint = [2,9,0,0].

 

Any ideas?

Thanks
