Can you do a "Enter current programming mode" in software by
1. Holding down the button for 10 seconds.
The only "button" on the whole thing is the release button switch, and it is not connected to the EVSE electronics at all, hence the need for the paperclip. There is no way to detect it at present without doing that.
Again, I will not consider any upgrade that involves adding or changing additional hardware, it's got to be firmware only.
Keep in mind, the paperclip would not be something used often. The Rev 2 will ship with 16a mode for 240v and 12a mode for 120v. For most people they will never need to mess with it. If you do ever need to use less than that, then at least you have the option, and all you need is a paperclip.
The only other way to "talk" to the EVSE w/o adding hardware is by plugging/unplugging the J handle in a certain sequence. I haven't been able come up with anything else.
