Z-wave frequency and power supply

Hi There.

Is it possible to change Z-wave frequency? My country uses channel 20, 24, 31 which is 920.9 MHz, 921.7 MHz, 923.1 MHz need to change operating frequency based on regulation.

And does the power supply adapter support 220V as well?

Hi @tedd. The z-wave frequency is not changeable on any of our devices. Can you clarify which power supply adapter you’re referring to as well? You can find the power requirements for our devices on their product page on https://ring.com/. Once you select a product, you can scroll down to view the power requirements for each device.
