This is more of an informative post than a question. I'm writing commands to my Evse 5.0 using the older 8266 wifi processor and figured out that the $SC commands I was sending were being stored in NV Ram. So I tested by rebooting the unit and the last value I had sent was saved thru the reboot. Searching the forum here lead to a single mention of appending V to the end of the command to NOT save to NV memory. So I tested that by sending the unit $SC 22 , and later sending the unit $SC 17V . When it rebooted it came up as 22amp unit. I also tried to set the current higher than 22 and if I used the V it did NOT permit this. So that's a safety thing... you can't accidentally go above the hard limit. So in sum.... Write $SC NN to set the initial settings of the unit. This should match your breaker and wire sizes. Write $SC NN V to rapidly adjust current up and down without affecting the permanent settings or wearing out the NV memory. Cheers!
