I have had it installed for about 2 weeks now, with the Solar option. It was relatively easy to install and configure.
It has identified 7 devices accurately and 3 incorrectly (which I deleted or renamed).
As I have had no technical issues I cannot comment on the Support aspect of the company. Below are my observations / comments:
I am doubtful it will get much better in resolving more devices in my home at this time, but their model is predicated on building a database from experiential data. So over time and with user cooperation it could conceivably get more accurate.
They need to develop a broader user inclusive means for device detection. I can turn a device on and off and see the change in the consumption at a very fine granularity. I should be able to tell the system it is device XYZ. Unfortunately you cant today.
The Solar sensing is very accurate. I was able to compare it to my inverter readings and was getting a ~5 Watt delta.
I am most concerned that if the company goes out of business or is acquired, that the device will essentially be rendered useless, or a new business model charging for the web based data base / monitoring will be enacted.
It is a useful device for a home energy audit. I have detected for example my water heater is probably the worst electricity consumer and due to its age would be the best appliance to upgrade at this time.
After the audit, I cant say it is probably as useful. I think they should change their business model to some degree to go after electricians or power companies to provide customers with an audit service. (They need to grandfather those of us that bought it however)
