Google home not working after HA upgrade

Hi,
i have hass.io manually installed on raspberry pi3, with relay and ds18b20 connected acted like termostat. i had HA v0.85 working well, with nabu google home integration to expose my entities to my google home mini.
i could ask google “ehi google, what is the temperature inside my home”, but after upgrading to v0.98 google home mini say “sorry i didnt get any response”. Note that i turn on/of the relay it’s working well.
How can i debug this problem?
