Google Home, Ecobee issue

Symptom: When I say "Hey Google, set the thermostat to 70 degrees", assistant responds with : "OK, setting the home thermostat to 70 degrees". The change never takes place.

I can set the thermostat using HE, without issue.

Ecobee is not directly integrated into my Google Home, instead the only defined thermostat is the one sync'd from HE. I know I could fix this by not publishing the Ecobee to the google assistant and then linking Ecobee to Google assistant directly, but I'd rather just have my thermostat linked in one place.

I'm using HE Ecobee Integration 1.0.2
I'm using HE Google Home built in app.

Has anyone seen this (mis)behavior before? A search doesn't suggest so.
