Re: Does a home power meter-base exist which uses BlueTooth?



The Blueline method is one that has been used in DIY setups for a few years
(although not wirelessly). It has the advantage of reading the power
company's meter disc revolutions so it will agree with their readings. It
also has the advantage that it does not require an electrician to install.

The other one requires an electrician to install it. Without additional
technical details I would be leery of its accuracy.

In either case I would want a serial interface so I could access the data
from my HA system.
