I want to control a tellstick znet lite if there is a built in way would be amazing but is there a way to do it through Google home where hubitat sends a command to Google that then sends a command to the telstick gateway want to control 433 MHz devices
Unless something has changed recently, Google Home Routines can only be triggered via a Voice Command or Specific Time of Day. There is no simple way, using the Hubitat built-in Google Home integration, to trigger a Google Home Routine.
This can be done though with Amazon Alexa, often even without owning an Amazon Echo device. Simply install the Amazon Alexa app on your phone, link Alexa to Hubitat using the Hubitat Skill, and then link Alexa to your Tellstick znet lite (if supported.) You can then use a Hubitat virtual Motion or Contact sensor as a trigger to an Alexa Routine.
