Cloud free EV chargers

Hardware
1

I have 2 Enel Juiceboxes currently. There used to be a cloud based integration that worked with them.

First, Enelx changed the firmware and broke the integration.

Subsequently, they shut down their cloud servers.

The charger are now dumb as a result.

I’m looking to replace one or both of them with smart chargers that can operate fully cloud free.

The main requirement is some sort of electrical certification, such as UL.

It would great if the charger could support 48 amps / 11.2 kw for my new Equinox EV. My current Juiceboxes are on a 40amp circuit and can only charge at 32 amps max.

Being outdoor rated would also be a huge plus, also, as the Equinox EV is large, and a very tight fit in my garage.

Is there anything currently on the market that would meet these requirements? I have done a fair amount of research and come up empty, so far.

OpenEVSE

They offer conversion kit for juicebox

Thank you ! I did not know that.

I would not be able to install the kit myself due to vision issues. I think the UL listing would be void as well after opening the unit.

Even the complete OpenEVSE units are not UL listed, only lab tested, which may not be good enough for insurance purposes.

They do have a 48 amp charger, but it is not outdoor rated, unfortunately.

Are there any other options besides OpenEVSE ? Pricing is not the #1 concern. The feature set is more important to me.

Chargers that support the OCPP standard may be an option. There is a Home Assistant integration that supports this standard:

Installation — home-assistant-ocpp documentation.

This charger may be an option:

Thanks ! That looks much better than the OpenEVSE !

While I myself use OpenEVSE i heard a lot of good things about GO-e chargers. They have open public API, OCPP and even MQTT support.

I have no idea if they are available for your region as I only seen them with Type2

It appears there are no US type 1 versions.

I wanted to follow up on this thread. Are there other options or any updates for EVSE’s that work locally with Home Assistant locally? (preferably UL listed for US)

Indeed, website states $199 for unlocking. I assume this only affects new purchases? An older used unit should not have this limitation? Or does OCPP rely on some kind of cloud connection (at least initially)?

I saw a comment on youtube that it only impacts Canadians but haven’t been able to confirm it.

IE the firmware update removes all the menus but if you contact support and you ordered before sept they may unlock it but not after or if you are not in Canada.

They really need to clarify what is going on but support basically told me I am SOL I am in Canada.

I decided to use the OpenEVSE kits after all. Had a local electronics repair guy do it on 3 units for less than the price of one kit. They are all working fine.

There is support for dynamically adjusting the amps, which controls maximum charging power. I may take a stab at writing some sort of automation to follow real-time power usage from my smartmeter sensor on the Rainforest Eagle 3, and adjust the amps on the OpenEVSE to try to self-consume and zero out the grid export from my solar PV during the day. Grid export is much less favorable than self-consumption with PG&E NEM2 rates (and especially bad for those on NEM3).
