Ouch! Indoor only use sucks! I'm not going to bother mentioning this device in future, as it's really only of any use with a home based, indoor, "dumb" EVSE and as such not worth what they are asking for it.

I supposed that I could use my J-1772 extension, and run the cable through a hole in the wall, connect it to this thing, run the extension back out the hole, and plug it in that way. Naaaah...

No.

Chargepoint never tells you SOC while on Level 2 but it does through Level 3. Is that the reason?

Yes.

Wow, that seems like a pretty big oversight when they decided to make this a universal plug.

The smarts are in the car along with the charger. The J1772 is just a fancy extension cord, nothing more.

CHAdeMO chargers are actual chargers feeding DC and regulating the voltage current. It needs to know lots of parameters about the car, and does lots of reading and handshaking before connecting and charging.

Interesting. I'm assuming this is why it takes longer when you plug in CHAdeMO before you start getting "juice?"

The smart plug is working beautifully! I've even set it up so I can tell my Google Home to start or stop charging. :)

The Juiceplug looks very interesting except for the "indoor use" recommendation (which is strange since most J1772 plugs are rated for outdoor use.

If using a 120-volt "smart plug" to control the standard Nissan EVSE, you need to be aware that the internal switching contacts may not last very long if it is frequently used to interrupt charging because the contacts will be interrupting 12 amperes. It should last a long time if just used to start charging because it will not interrupt high currents. The plugs are probably intended to switch light loads such as lighting, computers, TV, etc. that only draw a few amperes.

I can think of a workaround that would let me use one in my garage, but I'm reluctant to make the required hole(s) in the garage wall. Maybe they'll make a weatherproof one (I assume the issue is with the WiFi components, not the J-1772 part) later this year after hearing "If only it were weatherproof" as a reason for lost sales.
