Google Home integration

Hi, I have two Ubibot WS1 sensors and both are linked to Google Home. The first reports temperature and humidity levels correctly. On the second sensor, I use an external temperature probe. When I ask Google 'what is the temperature in the greenhouse' it always reports the value from its internal temperature probe which is inaccurate. Is it possible to get Google Home to report the value from the external temperature probe instead?

Best regards, Ian
