Now this is interesting!

Hey all,

Looking for some input here. After seeing I’m probably spending way too much on my gas and electric bill, I’m beginning a search for a decent electricity monitor, and (hopefully) one that works with XTension.

What I’d like to do is to be able to monitor as close to individual outlet level as possible, but by breaker would be OK too. That might be overkill, but the way the house was wired, some of the way the circuits in the breaker box were set up seem odd to me.

Also note I do not have a Smart Meter. I opted-out for a variety of reasons.

One I seem to like is this: http://eyedro.com <http://eyedro.com/>. The cost seems acceptable, and simple to pick up. It already has a Cloud interface, but hopefully it can bee hooked into XTension.

Chad’s idea of TED seems nice, but adding all the wiring from their spiders might be more than I want to do.

Open to suggestions and possible pain-points, so thanks in advance.

Tom

My apologies if this has been discussed many, many times before.

I monitor my refrigerator, chest freezer, upright freezer, geothermal heat pump, well pump, outdoor outlets used for stock tank heaters, water heater, and the back up electric strip heater in the geothermal unit (which we've used one time for a total of 16 hours in 5 years.  But in that time it used as much as our usual total usage for 4 months!)

But also because I'm reluctant to lose the monitoring and decision making info TED gives me.  We're slowly working our way off grid - original plan was to build a grid tie system that would offset our bill, and use the newly freed up cash flow to purchase batteries and such in phase.  Then our REMC changes the rate they buy power for, and now it may be cheaper to go off grid one "system" at a time.  TED gives me detailed data I can use to decide where the breakdown is between increasing efficiency, changing our usage pattern through lifestyle choices, and simply buying more/larger solar panels and batteries.  I want to add more spiders to track more circuits (which we currently don't have yet...), including those on the generation side, to get even more useful data.  But it floods the power lines with data, so moving back to XTension is going to mean using control technologies other than X10, which has all evolved much in my absence...
