It does have power failure detection and notifications. Also claims a range of 400 ft. Just wondering if these features will work or require a custom driver for C7/C8.
Zooz says it will work on hub platform version 2.2.9 or newer (which you are likely running by this point) but that a custom driver may be required to access advanced features. A community member has developed such a driver here if you find features you want that are not available with whatever built-in driver it will choose offers:
It should be noted that the range and repeating functionality are not affected by driver choice.
Already got you covered , as already posted there is a driver created for it.
There is a powerSource attribute which will change if it goes to battery power. You can create whatever alerts / rules you want based off that attribute. It is pretty quick to send the message in, so you would know right away.
