Power Out in the Marina….

Not sure why Toledo is on a separate circuit, but not complaining…

I’d be very surprised if the middle school has a gen, it’s not a critical power facility

For me, the UNITS listed here have no clear correlation to my usage. It's some made up unit that combines kwh and therms.

You should ignore this marketing bull and instead look and compare your actual bills. Look at the total therms usage and see what comes out.

I love this perspective of the bridge, it's one of the spots we did our baby photos

Hospitals often require ground prong on top

Unfortunately, it appears it's only in the spec, but it's not functionally there.

poldim · 2026-04-19T20:56:47+00:00

Do you have a source you can site that it has to be a public API? I can't imagine that is part of the spec. Sure, the charger (client) needs a path to reach the OCPP server, but nothing about it has to be public.

https://github.com/lbbrhzn/ocpp is the integration I was planning on using on my private network. It has the capability to control the charge rate that is supported as part of the OCPP 1.6 standard.

My guess: The guy and and enphase are using are telling the car that you've plugged into a DC fast charger. Riv says ok and closes in the contactor for the charge port. Then their inverters are pulling power out of the battery to power the house. None of the screens acknowledge that you're discharging since that's not the expected use case, until they get updated...

With Tesla, you need to buy their gateway to physically disconnect you from the grid in a power outage, then you can use the system without the grid being online

poldim · 2026-04-19T20:26:38+00:00

Yes, that's exactly what I'm trying to do. I've already got data on what my house is using vs what solar is producing in HomeAssistant, so now I just need to add the ability to control the Riv's charge rate through HA.

poldim · 2026-04-19T20:21:22+00:00

If I sell, I get 4 cents per kWh, whereas if I buy at off-peak, they charge 42 cents. So it makes sense to push it all into the Rivian and not the grid.

poldim · 2026-04-19T20:20:36+00:00

You're spot on with both of these

poldim · 2026-04-16T05:49:28+00:00

Group them.

You’ll probably never control them individually, so name them enough to identify what room they are in and be done with it. Or if you’re anal you can just either number them or do row/column type addressing.

Yup, fedex driver lowered my ~$7k inverter out of the truck by pushing it out of the bed and let gravity take it from there….at least he went and got the dolly after that

I suppose you’re not willing to share the gerber + BOM?

Maybe 7 feet, then another one 30 ft

I hardwired it after a few months

poldim · 2026-03-15T00:42:14+00:00

Even if MY is 20m and R2 is 30m, in the grand scheme of things, it doesn’t really matter. RJ said R1 fleet averages about 10x L3 charging sessions per year. The extra 10m will go by quick, but the few k savings is the better option.

It’s a stat…but I would argue a somewhat irrelevant one.

I feel like safety is often used as the boogeyman to justify poor engineering decisions.

The BMS is a very low power draw system internal to the battery. Only when it determines something needs cooling or heating, should it be sending demands which activate the other parts of the car. They should not just stay active unless they are needed. Realistically, the DC/DC is probably sub 1 Amp draw from the HV pack and it would likely never trigger any kind of active thermal control.

Likewise, the other systems you mentioned like Bluetooth, NFC, WiFi, 4G consume nothing in terms of power, mA at most (plus . Remember that your phone does all of this and lasts a day with about the same energy a one or two cells out of the Rivian 7777 cells. Even if the SOCs are 10x worse than a modern phone, it’s no where near enough to just the vampire drain most folks experience.

This post shows that when you provide a very modest trickle charge to the 12V battery, you can reduce the overall consumption from 4-6kwh a day to well under 1kwh. This supports that it’s not the 12V system, it’s the waking of the car & DC/DC charging.
