Japanese Sanwa Supply introduced an innovative new power draw meter that not only measures power draw at wall like every other product in its class, but also tweets about it. The TAP-TST9 from Sanwa Supply is equipped with a WLAN device, which when configured, automatically logs into Twitter (you can set up a separate account for it) periodically, and tweets about your current power draw, any unusual increase or drops (indicating that something is wrong with the connected appliances) are reported. In its tweets, the TAP-TST9 provides readings of voltage (V), current (A), power draw (W), the amount of money spent in powering the appliances (in a set currency, when the local power tariffs are programmed), and even carbon footprint (kg)! Measuring 60 x 36 x 130 mm (WxDxH), the device weighs about 145 g. It is priced at 29,400 JPY (US $362).
