I’ll be flying to NC, USA on June and I’ll be staying for 2 weeks. I’m planing to purchase US ST and several Z-Wave sensors and bring them back to the Philippines. I know that ST is 120V, while Philippines has 220v. I can take care of it by buying a voltage converter. But how about the frequencies? US Z-Wave uses 908.4 MHz. The local frequencies used are:
GSM: 900 MHz and 1800 MHz
UMTS: 2100 MHz and 850 MHz
Will it be ok? I’m not familiar with frequencies and stuff, hoping someone can enlighten me. Thank you.
You should probably buy a version that uses the correct Z-wave frequency. You never know what may be using that frequency. Cell phones are by far not the only things you have to worry about.
First you should check what the zwave frequency is in the Philippines and then decide on your hub.
The last thing you would want to do is buy a hub that uses an illegal frequency.
e.g. the US hub uses an illegal frequency if used in the UK.
I suggest you do your research.
Philippines
STANDARD: ETSI EN 300 220
Z WAVE FREQUENCY:868.40 MHz, 868.42 MHz, 869.85 MHz
RESIDENTIAL VOLTAGE: 220 V
FREQUENCY:60 Hz
USA
STANDARD:FCC CFR47 Part 15.249
FREQUENCY:908.40 MHz, 916.00 MHz
RESIDENTIAL VOLTAGE:120 V
FREQUENCY:60 Hz
interesting discussion here:
so this means the Philippines uses EU zwave frequency.
which now leads to this possible issue.
with how mostly things are imported from the U.S. and have not heard of any regulation violations as far as I know (i could be wrong though) i doubt it if you will have any issues.
