Before [Steve] realized that it didn’t play nice with his network, he dismantled his Energy Detective TED 5000-G to see what made the device tick. He put together a nice teardown with high-res pictures throughout. Each component of the TED 5000-G is dissected, with the exception of the current transformers, which he claims are pretty boring anyhow. The gateway module is particularly interesting as it contains both an Ethernet interface as well as a 802.15.4 radio for wireless communications. While the device is still a bit expensive at the moment, the gateway module could be useful in projects requiring PLC or ZigBee communications some time down the road, once prices ease a little.
