I have one of those hooked up to the main feed circuit in the fuse box, so basically monitoring the total energy consumption of my house. It is working very well, and seems to give fairly precise measurement reports.
For monitoring of individual appliances, however, I am using Fibaro Wall Plugs (FGWPF-101). These devices are very well suited for the purpose. I am currently using these on my washing machine, drying machine, dishwasher, freezer and water heater.
Apart from being very nice devices, that are rock solid in operation, I can see the following two benefits:
- Ease of use - simply plug it into the socket, and then plug your appliance into the device.
- Master switch - If you happen to leave for an extended vacation, and forgot to turn off your washing machine, you can simply cut all power to the unit,
