🔋 Testing the HomeWizard Plug-In Battery with Home Assistant

This new device claims to be a plug-and-play home battery that should work with Home Assistant—just install it yourself, no electrician required. But does it actually work as promised?

I unbox it, set it up, and put it to the test! Watch here: youtu.be/WOxB-d-ofj4

YouTube🔋 Does the HomeWizard Plug-In Battery Really Work? Unboxing & First Test! ⚡By Franck Nijhof (Frenck)

I had a calendar event and home assistant automation set to trigger the house battery and car to charge overnight while the Octopus Agile electricity price was practically zero for almost 7 hours and it didn't run. So, we're pulling from the grid this morning which sucks. I know, I know, first world problems. It just irks my paying 15p/kWh when we would have been paying practically zero to fill the battery and running off that now.

Here's the details of the NSW home battery technically-not-a-rebate that I mentioned: solarquotes.com.au/battery-sto

Seems like an excessively complex way to subsidise new home battery installs, but for NSW residents it could translate to a discount of about $2k.

It seems Tesla retains cloud control of the batteries it sells, at least in Australia, but not in the USA.
Australian politicians have a lot to answer for. Arguing about nuclear power, and gas-led recovery, when they should have just focused on making renewables more available and better regulated.
Spending $15k on a Tesla battery that you can’t control without cloud connectivity seems like a really bad idea. Especially when it’s just because of a geo-lock.

Guess who forgot to disable the early morning home battery charging session last night??? Yep, this guy. It's not going to have cost us much as there was only about space for 3kWh's, it's just frustrating.

I set it up to take advantage of the Octopus Energy Agile price drop early on Sunday morning, to feed the battery and our EV, and then forgot to disable it again. I really have to find a better way to manage this in Home Assistant.

Looks like it's going to be a good #Solar generation day. The #HomeBattery got down to 26% around 07:50, about the same as yesterday, but unlike the grey and overcast weather of yesterday we have bright sunshine and almost 3.5kW of generation already at 09:10. Time to get some clothes washing started and Eddie our #EV plugged in to soak up the excess.

Darn it, I got caught out again. I set the #HomeBattery to discharge before midnight. The plan was to make a Brazilian mega bucks (ok, 15p/kWh for anything we export) but I forgot Eddie, our #EV, was primed and ready to recharge too so he ate all the electrons instead. Not the end of the world.

With today's crazy, near zero, price for electricity on the #Octopus #Agile tarrif, we'll just export the battery again and fill up a second time.

Took a chance overnight and didn't add any extra charge into the home battery based on the solar forecast of 26kWh for today. I doubt we are going to see all 26, especially at this time of the year due to shading from next door, but let's see if we're anywhere close. Somewhere around 9 will run most of the house load for the day and anything extra will help top-up the battery.

A page from our home automation system showing the current solar generation of 2 watts (it's still mostly dark), the house load is 377 watts and the home battery is exporting around 390 watts to cover the load. The battery is at 18 percent state of charge.

@davidho this is an excellent example of how the #electricutility grid is evolving from central energy suppliers to centralized energy managers.

Every business and household should participate in rooftop solar and have their own battery backup ( through a #homebattery, and their #electricvehicles adding significant energy storage for a home )

The grid becomes the central energy buffer. And everyone uses less net energy, and becomes more self reliant during outages.

Hmmmm. Huge battery pack bought via Alibaba explodes and destroys house. There might be a cautionary tale or two in there. Like 30kWh of energy stored in compact metal boxes of dodgy provenance and mounted right inside your home.

pv magazine InternationalInvestigators still uncertain about cause of 30 kWh battery explosion in GermanyA lithium iron phosphate (LFP) battery system recently exploded in a home in central Germany, preventing police and insurance investigators from entering due to the high risk of collapse. The explosion may have been preceded by off-gassing, but it remains unclear whether an external ignition source was the cause. Some scientists say thermal runaway may have triggered the blast.
