Re: Tweet-a-Watt plus Relay
Thought I'd post a summary about a result I got today regarding switching mains with an XBee. This wasn't done in the context of a Kill-a-Watt, but thought it might interest some nonetheless.
The setup is simply a battery powered XBee mounted on the Adafruit adapter. DIO1 of the Xbee is configured to be switchable. The relay I'm using is a solid state variety that I got off eBay - 10 of them for $30 - a fantastic price given that Ultimate Electronics sells the m for $30 apiece. The SS Relay is made by Mager, requires 3V to switch, and can switch a load of up to 25A. The product number is MGR-1 D4825. I simply connected the switching connections on the SSR to the GND and DIO1 on the XBee and then was able to switch my office fan off an on by sending the appropriate remote AT commands... Works great!
Bye for now, Kurt
