It’s not for everyone, no doubt. Batteries appear to be about on a yearly average of $20 for 40+ sensors based on what I’ve seen so far. Buying in bulk, not at Home Depot or Radio Shack of course. Not that bad, total cost I’ve put in is $2907.93, retail value of all that would be around $4934.71.
I’ve already seen between $30-55 savings on average a month. My electric bill would normally hover around $200, it’s more around 130-150 roughly these past 8-10 months. Ok, so really that’s more like an 8 year payoff.
My time isn’t really something I’d count, in my case, this is a hobby. That would easily run into the tens of thousands I’d bet!
The actual graphing took a few hours of time to setup and a few more to tweak, maybe 8-10 total. All my actual automation’s is what took the most time. Setting up the system and sensors isn’t too bad, automating it with the complex crap I’ve decided to try, that’s a time sink.
If the “average” person thinks they want HA, they will learn after buying that fancy WeMo switch very quickly how bad an idea it would be to try without actual dedication. I still don’t believe HA is ready for mainstream use. Individual things, like the Ring doorbell might be, but not TRUE automation.
Now the caveat to this is JUST power monitoring. Setting up a bunch of smart outlets, hub, and graphing, you could get it done over a weekend. That would be more than enough to start saving lots of money. I have Harmony’s, Echo’s, Kuna’s, DVR’s, so many motion and contact sensors, etc. Most people don’t need any of that crap to realize the energy saving benefits.
Stupid forum keeps blocking c r a p. That hasn’t been a bad word since the 1800’s!
