Fox-ess make a line of solar inverters. These inverters communicate with www.foxesscloud.com and this is an attempt to understand and document the protocol used.

From snooping the traffic from an inverter I have seen that a TCP connection to port 10001 on www.foxesscloud.com is made and kept open.

Aside from the standard TCP keep-alive and Ack, data is sent from the inverters wifi module periodically (approximately every 30 seconds).

Below is a list of the packets I have seen and an explanation of the contents.

general packet structure

The packet starts and ends with the following (byte values written in hex)

### packet 06
