- IFTTT & Alexa Integration: trigger IFTTT applets based on high or low temperature set points reached (when device alerts). Voice query Alexa for the temperature (only; humidity not supported at this time). Triggering Alexa routines is not supported at this time.
- PLUG, PLUG & PLAY! Take advantage of direct ethernet connection and be online almost instantly when you plug your Hub into your router or network switch. Or, use hot spot mode to connect to your WiFi network in moments. Add devices in seconds using our Scan & Play QR code scanner in the app! Set your notification preferences, test your new sensors, then enjoy years of trouble-free operation!
