Firmware 4B

[fboundy]

HMI Firmware 4B introduces a completely different way of controlling the charge slots. According to the latest code list document (https://oss.soliscloud.com/doc/SolisCloud_control_api_command_list.xlsx):

New optimized earnings parameters. When the read parameter CID is 6798 and the result is 0xAA55, 
use the new optimized earnings parameter.

The relevant codes for the individual entries seem to be those listed below.

I am not clear what Volt n controls as it doesn't appear on the web GUI. It is probably the minimum voltage at which to charge.

It's also not clear how the Time Slot n codes are set but my guess is that it will be using a string similar to the old version since they are reported back as "00:00-00:00"

Finally , by polling all the codes from 5916 to 5986 I have found that 5936 returns "0,0,00:00-00:00,00:00-00:00,0,0,00:00-00:00,00:00-00:00,0,0,00:00-00:00,00:00-00:00,0,0,00:00-00:00,00:00-00:00,0,0,00:00-00:00,00:00-00:00,0,0,00:00-00:00,00:00-00:00" which looks a lot like 103 did under the old system.

For reasons I won't bore you with my system is now offline until daylight but once it is back up and running I'll play around with this a bit more and investigate how easy it is to set these parameters.

I will endeavour to put together a PR to address this.
