HI, I purchase Fibaro motion sensor. from United States. when I try to install Fibaro motion sensor Homey bridge was not recognized it. So I read a little bit in the internet and I understood that in my region Z-Wave frequency is different. So my question, how can I change the frequency from automatically to manually. PS. I able to install motion sensor only when I change my region to US. ---

That is not allowed, As you probably have read in different countries different frequencies are assigned as unlicensed industrial, scientific, and medical ([ISM](https://en.wikipedia.org/wiki/ISM_band)) band. > **[Z-Wave | Radio frequencies](https://en.wikipedia.org/wiki/Z-Wave#Radio_frequencies)** > > Z-Wave is designed to provide reliable, low-latency transmission of small data packets at data rates up to 100kbit/s, and is suitable for control and sensor applications, unlike Wi-Fi and other IEEE 802.11-based wireless LAN systems that are designed primarily for high data rates. Communication distance between two nodes is 200 meters line of sight outdoors and 50 meters line of sight indoors, and with message ability to hop up to four times between nodes, it gives enough coverage for Z-Wave uses... For Homey Bridge and older Homey’s it is Fixed, Only on Homey Pro (Early 2023) you can change it for testing from the Development Tools. If you change it for testing you are warned: ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/9/b/9b3c3048541a2a953e17493fec0869ab776b5edf.png) Beside the liability, you probably are going to add more device and these all need to be from the same Z-Wave zone. The shop should have send you the correct region devices. ---

issue solved thanks
