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 ( seeedstudio.com/wiki/Grove_-_SPDT_Relay(30A ). If there is simpler way, please notify me.
I have 220 V in the light switch. Can the relay handle that power for long periods of time ? 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 3.3v - 6v. 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.
