I believe I read Juicebox is working on a way to directly connect to the EVSE with WiFi but as of now it's internet only and somehow through their servers. When someone asked what happened if their servers went down, their response was they had a very redundant system, of course no internet connection, no way to change the output current as of now. Again you can use the EVSE, you just can't change the output current from it's last setting.
I think you'll be OK with 6a, EVSEupgrade goes down to a 6a setting and I've never heard of anyone having a problem with it. I believe 6a is the lowest current allowed with the J1772 standard EVSEs use.
If you are of the smartphone generation then the JuiceBox is the way to go. Personaly I do not want to use a smart app on my phone to control my EVSE.
I build OpenEVSE units with a fifteen dollar multi function meter that stores stores KWH until reset; That works for me. I just want to walk over to the unit to read it. It really depends on your generation. I just want an EVSE that is safe and works for me. Most Chinese EVSE's fail the GFCI test since that requires a lot of skill to get it to work without falsing. Most Americal EVSE's like Clipper Creek, JuiceBox and OpenEVSE pass the required GFCI test. As far as I know it is just the Chinese units.
