Please note that in the beginning of 2018 Google change the way of communication. That caused issues - HABridge is now not able to communicate with Google Assistant directly. You need to link account - which you can't - as this is not a real bridge. Why? No clue.
You can look eventually into other solutions - like OpenHAB - which is not so easy to set up- but could be used with Google. Or wait a month for new Z-way server which probably would have finally direct communication. It is already supporting Alexa.
Normally, if you are doing home automation - you would expect that it would be possible to steer your home using voice systems. Of course, we can spend some time on OpenHAB to make this voice activated... but it would cost a lot of time.
