I looked at emporia, that is very affordable at $200.
I will not go there because I am making the decisions up front about appliances and strategies.
I put in the plumbing for a GE Profile ventless heat pump washer dryer in our closet, in addition to a traditional W/D setup in the basement.
I decided on a Rheem ProTerra 50 gallon hybrid water heater, which is controlled via Econet and does it's own energy monitoring.
I'll have enough geek out features with the hybrid inverter and net metering and those things to satisfy me.
I took a total hack at how much panel I need, by just filling the south facing surfaces and leaving the 36" path up each roof pitch that is typically required.
My AHJ is so cool though. He said he could get a letter from the fire department stating that they will NEVER go on the roof for a rescue, and I could eliminate that path.
I want it for my access.
My hope is I will have excess energy and not need to consider it at all.
For the price point it is very affordable. What stops people is that you have to open up your main panel and put CT clamps around the wires for the circuits you want to monitor. I also have a Emporia EV Charger which so far I have been happy with.
I have the Rheem ProTerra 80 gallon Hybrid water heater (4 people in my household) so far have been happy with the water heater. I did have a issue with the thermistors in the first year of ownership that had to be replaced, paid for by the warranty. The heat pump water heater is basically two water heaters in one, heat pump and has a standard element to heat the water. So that means the heat pump stopped working (thermistors failed) I just switch the water heater to electric only mode. One thing I did before install was to investigate how to replace the anode rod because it has 1/2 ton heat pump on top of the unit so you have to take the top off that to then go down to access the top of the anode rod. So what we did is leave the screw permanently off the top of it that faces the wall so we can get the top of the unit off easier. Mine is in my garage and while it is nice in the summer to have a 1/2 ton AC unit blowing cold air it struggles a bit in the colder parts of the year, not that it gets really cold in San Diego. So during the winter I switch the unit to High Demand mode.
I just recently got Home Assistant installed on a PI box and I am exploring what I can do with that as far as aggregating all my smart home stuff together.
Personally I have found with solar that if you get a small bill, you use energy more.
In 2024-2025 True Up - I used 41 MWh of power for my house, pulled 14.8 MWh from the grid, Exported 6 MWh to the grid and produced 35 MWh of solar from 20kw of panels (DC) with 75 KWh of LFP batteries. This netted me out at the end of the true-up period (12 months) a total bill of about $300 from SDGE which made me fairly happy.
I also have 2 BEV's, a pool(In the process of getting rid off), spa and the house is fully electric. The only time we use Propane is for emergency heating with the heat pumps which is often in San Diego.
