A small library that encodes and decodes data from Solarman data loggers. It works with wifi kits with a s/n starting with 17xxxxxxxx.
Please be careful with changing constants, as you can accidentialy send different command. So instead of fetching real-time data, you could change some setting of an inverter (this can be really dangerous).
Refer to the example to see how it can be used.
Hope this helps you to understand how the protocol works.
