[L81ker]

Feedback

Please add the text that there are different versions of Z-wave with different frequencies e.g. for US and Europe, be careful to purchase the right one., and if the recommended list includes references which are only for one market, add that info if it is known.

Suggestion 1: provide a link to the Silicon Labs frequency list which is extensive: https://www.silabs.com/wireless/z-wave/global-regions

Suggestion 2: add the below text
"The Z-Wave protocol operates on the low-frequency band e.g. (908.42Mhz in the U.S. and the 868.42 MHz band in Europe). Be sure to choose devices which work in your country and be aware that all devices in your network must use the same frequency band."

Suggestion 3: as an example,:

"Silicon Labs UZB-7 USB Stick (Silabs SLUSB7000A (908.42Mhz Version) or SLUSB001A (868.42 MHz version))"
