Maybe a year from now we'll have...
Remember it was only about one year ago we began to include measurement of current during charging. We've come a long way. Where will we go in twelve months!
The 50A kit has a I2C, SPI and TTL Serial port so all kinds of devices can be added. The ESP8266 connects to the Serial port and is behind developed on the OpenEVSE v4 (50A kit).
OpenEVSE software and hardware engineering so far has kept a principle of protecting and enhancing the installed base of OpenEVSE users. You probably cannot guess how many OpenEVSE systems are in use worldwide. Go ahead, offer your guess for fun.
When I first wrote the dream of a new MPU as the Ti CC3200 it was more to spark conversation than anything else. Yes we have been experimenting with the ESP8266 as a co-processor add-on to existing OpenEVSE designs. That work is 100% compatible, consider it an add-on.
Do you have some concerns, any worries?
