Before Emporia I was using a TED 5000, until it died. While it wasn't as accurate as the Emporia and the calibration steps were too course to dial it in properly I really liked the user interface and how the data was displayed. Would have went with their new Pro 2.0 system without another thought but its been delayed for at least a year now due to semiconductor shortages.The IotaWatt is frequently favored over similar products like the Emporia Vue as the data isn't stored on the web. @FilterGuy says the Sense is "okay". Check out @MurphyGuy 's post for a fabulous installation of the Iotawatt. The Energy Detective (TED) seems to be a cross between the Iotawatt and Sense. There are also two other products I've heard about: the GEM monitor and the RIO. Or, if you're handy there's the DIY (WIP) approach.
The Brueltech GEM was mentioned, this same company also makes the ECM1240 which has an optional ZigBee module supposedly making it compatible with the Universal Devices ISY994i (now discontinued) and Insteon home automation systems. Was seriously thinking about trying it out but the cost and complexity were screaming not to do it.
Many years ago I had purchased the Brueltech ECM 1200 energy monitor. Its a simple device with only 2 CT's, plug in power supply, downloadable data logging and was advertised as being able to measure True, real power. It still works and makes a great portable tool. It even included a 120V plug in adapter with an exposed wire loop so the CT could be used on any plug in appliance without pulling the receptacle out of the wall to expose wires.
