Review on SwitchBot Door Alarm Contact Sensor - Enhance Home Security with Wireless Window Alarm & Door Sensor, Alexa Compatible by John Stowers

Alexa integration (requires your hub or mini-hub) limited to open/close contact sensor. No other functions are supported. You can't start Alexa Routines with a contact's touch button, proximity sensor, or ambient light sensor. I was particularly disappointed that the button wasn't supported because I was hoping this device would replace the Echo button I'm starting the process with now. This touch sensor can really only be used to trigger scenes created with the Switchbot app to control other Switchbot devices.
