Is is possible to use Alexa/Good Home as an Alarm Annunciator?

I have some processes where if the temperature gets above a certain value, then I would like to know. Is it possible to use either Alexa or Google Home as an annunciator to tell me when this occurs and if so, how is this done? I have both Alexa and Google Home integrated through Nabu Casa

I am also looking for something similar.

You can use Alexa to announce using this
