Hi,
I want to do a wireless light switch, but i don't know from where to begin.
I would like to use the Grove Xbee Carrier ( http://www.seeedstudio.com/wiki/Grove_-_XBee_Carrier ) together with a Xbee shield and a Grove Relay ( Grove - SPDT Relay ). If there is simpler way, please notify me.
I have 220 V in the light switch. Can the relay handle that power ? If not, what relay should i use ?
Also, since Grove and Xbee need power, can i somehow wire them to get power from the wires of the light switch ? I guess i need an adaptor or something since Grove needs only 5 V. I dont want to use a battery or something, because the XBee drains a lot of power and i would need to change the battery weekly or so.
Thanks,
