Shouldn't this be "Relay Noop" or some such?
What message does it give when it fails to detect a proper Ground?
I guess a list of the tests, what they actually do, and
the Error messages they display would be very helpful.
Thanks, Gary

The Plus board's I/O pins are fully populated, so if you want to add LED's you need to utilize the board's I2C expansion capability. If you have the Plus board's RGB LCD option and not fully implementing the button options (Select/Up/Down/Left/Right), you could add LEDs to the unused pins (besides the firmware mods required, the adafruit RGB/LCD software library would require modifiction).
Another option would be to add another I2C board. For RGB with fancy color transitions, you might want to look at using one of ThinkM's BlinkM I2C/RGB module.
Or for simple LED on/off function, you could add a "I2C I/O expansion board", such as the PFC8574. A module like this.. is about $9 on eBay with shipping from China. Problem is these have no space for mounting LED resistors or spare pins for taking Power or common ground, just the I/O pins.
garygid said:Chris,
Does the check for the test AC line being "HOT" involve
using the Ground?
How is this test done, please?
Load the hot line a bit to Ground, and look for some current?
Thanks.
garygid said:Great use of the opto-isolator to safely sense some current flow.
Thanks
chris1howell said:Aaron from Diversified Stage, Inc. has designed custom enclosures for OpenEVSE projects. His enclosures will be avaliable in both indoor and outdoor versions very soon at a very reasonable price. The enclosure will greatly reduce build time. They are pre-drilled for the most common parts externaly for AC/J1772, LCD cutout, Adafruit button and internaly for OpenEVSE board (with threaded standoffs), 30A relay, ground block, and fuses.
garygid said:Some dimensions would be helpful, at least for the box and the cutouts.
Pictures of the weatherproof version, please?
Very handsome little box. Thank you for posting. I am curious of how portable the 30Amp unit with this enclosure is. Next time if you build another one or if anyone builds one, would you please reports the weight on the finish unit (either with or without the J-cable). I am considering replacing the Rav4EV supplied portable EVSE (max 240Vx12Amp) with a portable OpenEVSE (max 240Vx30Amp).chris1howell said:The indoor version is 8 x 8 x 5. I believe the outdoor version has similar inner dimensions but is slightly larger externally. The screws are all external to the weather seal. I have a indoor version now. Diversified Stage just shipped me and outdoor enclosure so I will have more pics in a few days.
garygid said:What is the weight of these boxes?
Size of the cutouts?
Cool. Will you make this part of your open evse order ?chris1howell said:Indoor Enclosure $58 - Outdoor $95 plus shipping and tax for CA residents...
It is a bit less from Mouser, but you will need this one which is a 2 pole instead of the 1 pole in the original Mouser link.garygid said:This looks like a similar fuse holder, same manufacturer, but
for a lot less $$ from Mouser:
